Low-Dose Oral Minoxidil: Expert Consensus Provide Guidance for Treating Hair Loss
. With large randomized, controlled trials lacking, the guidelines authors and other dermatologists said the paper provides practical pointers that should increase clinicians’ confidence in prescribing LDOM for hair loss.
Comfort and Confidence
Benjamin N. Ungar, MD, director of the Alopecia Center of Excellence at Mount Sinai Icahn School of Medicine, New York City, said he hopes that the guidelines will “make dermatologists in practice more comfortable with the use of low-dose oral minoxidil to treat different kinds of hair loss, and therefore, more patients will benefit.” He was not an author of the paper, which was published online in JAMA Dermatology on November 20, but was asked to comment.
Members of the multidisciplinary Low-Dose Oral Minoxidil Initiation steering committee recruited dermatologists with hair loss expertise from 12 countries. Using a modified four-round Delphi process that required at least 70% agreement, the group of 43 dermatologists crafted 76 consensus statements. “Notably,” said Co-senior author Jennifer Fu, MD, director of the Hair Disorders Clinic at the University of California, San Francisco, “27 items achieved at least 90% consensus after the first two rounds, indicating broad agreement in expert practice.”
Indications for LDOM
At least 90% of experts concurred regarding the appropriateness of LDOM use for androgenetic alopecia (AGA) and age-related thinning and in cases where topical minoxidil proves ineffective or problematic. Additional situations in which LDOM might provide direct benefit involve follicular miniaturization, such as alopecia areata, or hair cycle disruption, such as chemotherapy. The authors also recommended considering LDOM over topical minoxidil when the latter is more expensive and when patients desire enhanced hypertrichosis.
Contraindications and Precautions
Before prescribing LDOM, the authors wrote, clinicians may consult with primary care or cardiology when contraindications (cardiovascular issues, pregnancy/nursing, and potential drug interactions) or precautions (history of tachycardia or arrhythmia, hypotension, or impaired kidney function) exist. Patients with precautions may require blood pressure monitoring, as well as monitoring for adverse effects of treatment. The panel also suggested the latter for all patients at the time of LDOM initiation and dose escalation. The authors advised against routine baseline laboratory and EKG testing in cases without relevant precautions.
Dosing Considerations
Along with systemic adverse event risk and baseline hair loss severity, key dosing considerations include patient age, sex, and whether patients desire hypertrichosis. Consensus on daily doses for adolescent females and males begins at 0.625 mg and 1.25 mg, respectively, and ranges up to 2.5 mg for adolescent females vs 5 mg for adult females and adolescent and adult males.
Presently, said Ungar, many dermatologists — including some who prescribe LDOM — remain uncomfortable even with very low doses, perhaps because of an invalid perception of cardiovascular safety issues including potential hypotension and pericardial effusions. However, recently published data include a review published November 7 in the Journal of the American Academy of Dermatology, which showed no significant effect of LDOM on blood pressure. And in a September Journal of Drugs in Dermatology article the authors found no impact on pericardial effusions in a 100-patient cohort.
Some dermatologists worry about the impact hypertrichosis may have on patients, Ungar added. Although incidence estimates range from 15% to 30%, he said, more than half of his patients experience hypertrichosis. “However, most continue treatment because the beneficial effects outweigh the effect of hypertrichosis.”
Practical Roadmap
Adam Friedman, MD, who was not involved with the publication, applauds its inclusion of pragmatic clinical guidance, which he said consensus papers often lack. “This paper sets a great roadmap for working low-dose oral minoxidil into your clinical practice, Friedman, professor and chair of dermatology at George Washington University, Washington, DC, said in an interview.
Rather than limiting LDOM use to AGA, he said, the paper is most helpful in showing the spectrum of disease states for which the expert panel prescribes LDOM. “We use it as adjunctive therapy for many other things, both scarring and nonscarring hair loss,” he added.
In appropriate clinical contexts, the authors wrote, clinicians may consider combining LDOM with spironolactone or beta-blockers. Friedman said that in his hands, combining LDOM with a 5-alpha reductase inhibitor (5ARI) is “absolutely outstanding.” Minoxidil increases blood flow to the scalp, he explained, while 5ARIs prevent production of dihydrotestosterone, which miniaturizes hair.
Fu said, “We hope these consensus outcomes will be helpful to dermatology colleagues as they consider using LDOM to treat hair loss in their adult and adolescent patient populations. We anticipate that these guidelines will be updated as additional evidence-based data emerges and are encouraged that we are already seeing new publications on this topic.”
Important areas for future research, she noted, include pediatric use of LDOM, the comparative efficacy of topical vs oral minoxidil, the safety of oral minoxidil for patients with a history of allergic contact dermatitis to topical minoxidil, and the use of other off-label forms of minoxidil, such as compounded oral minoxidil and sublingual minoxidil.
The study was funded by the University of California, San Francisco, Department of Dermatology Medical Student Summer Research Fellowship Program. Fu reported personal fees from Pfizer, Eli Lilly and Company, and Sun Pharma outside of the study. The full list of author disclosures can be found in the paper. Ungar and Friedman reported no relevant financial relationships.

Levonorgestrel IUDs Linked to Higher Skin Side Effects
TOPLINE:
, with some differences between the available levonorgestrel IUDs.
METHODOLOGY:
- Researchers reviewed the US Food and Drug Administration (FDA) Adverse Events Reporting System (FAERS) through December 2023 for adverse events associated with levonorgestrel IUDs where IUDs were the only suspected cause, focusing on acne, alopecia, and hirsutism.
- They included 139,348 reports for the levonorgestrel IUDs (Mirena, Liletta, Kyleena, Skyla) and 50,450 reports for the copper IUD (Paragard).
TAKEAWAY:
- Levonorgestrel IUD users showed higher odds of reporting acne (odds ratio [OR], 3.21), alopecia (OR, 5.96), and hirsutism (OR, 15.48; all P < .0001) than copper IUD users.
- The Kyleena 19.5 mg levonorgestrel IUD was associated with the highest odds of acne reports (OR, 3.42), followed by the Mirena 52 mg (OR, 3.40) and Skyla 13.5 mg (OR, 2.30) levonorgestrel IUDs (all P < .0001).
- The Mirena IUD was associated with the highest odds of alopecia and hirsutism reports (OR, 6.62 and 17.43, respectively), followed by the Kyleena (ORs, 2.90 and 8.17, respectively) and Skyla (ORs, 2.69 and 1.48, respectively) IUDs (all P < .0001).
- Reports of acne, alopecia, and hirsutism were not significantly different between the Liletta 52 mg levonorgestrel IUD and the copper IUD.
IN PRACTICE:
“Overall, we identified significant associations between levonorgestrel IUDs and androgenic cutaneous adverse events,” the authors wrote. “Counseling prior to initiation of levonorgestrel IUDs should include information on possible cutaneous AEs including acne, alopecia, and hirsutism to guide contraceptive shared decision making,” they added.
SOURCE:
The study was led by Lydia Cassard, Cleveland Clinic Lerner College of Medicine, Cleveland, Ohio, and was published online November 3 in Journal of the American Academy of Dermatology.
LIMITATIONS:
FAERS database reports could not be verified, and differences in FDA approval dates for IUDs could have influenced reporting rates. Moreover, a lack of data on prior medication use limits the ability to determine if these AEs are a result of changes in androgenic or antiandrogenic medication use. Cutaneous adverse events associated with copper IUDs may have been underreported because of assumptions that a nonhormonal device would not cause these adverse events.
DISCLOSURES:
The authors did not report any funding source or conflict of interests.

Post COVID-19, Long-term Risk for Autoimmune, Autoinflammatory Skin Disorders Increased, Study Finds
In addition, the authors reported that COVID-19 vaccination appears to reduce these risks.
The study was published in JAMA Dermatology.
‘Compelling Evidence’
“This well-executed study by Heo et al provides compelling evidence to support an association between COVID-19 infection and the development of subsequent autoimmune and autoinflammatory skin diseases,” wrote authors led by Lisa M. Arkin, MD, of the Department of Dermatology, University of Wisconsin School of Medicine and Public Health in Madison, in an accompanying editorial.
Using databases from Korea’s National Health Insurance Service and the Korea Disease Control and Prevention Agency, investigators led by Yeon-Woo Heo, MD, a dermatology resident at Yonsei University Wonju College of Medicine, Wonju, Republic of Korea, compared 3.1 million people who had COVID-19 with 3.8 million controls, all with at least 180 days’ follow-up through December 31, 2022.
At a mean follow-up of 287 days in both cohorts, authors found significantly elevated risks for AA and vitiligo (adjusted hazard ratio [aHR], 1.11 for both), AT (aHR, 1.24), Behçet disease (aHR, 1.45), and BP (aHR, 1.62) in the post–COVID-19 cohort. The infection also raised the risk for other conditions such as systemic lupus erythematosus (aHR, 1.14) and Crohn’s disease (aHR, 1.35).
In subgroup analyses, demographic factors were associated with diverse effects: COVID-19 infection was associated with significantly higher odds of developing AA (for both men and women), vitiligo (men), Behçet disease (men and women), Crohn’s disease (men), ulcerative colitis (men), rheumatoid arthritis (men and women), systemic lupus erythematosus (men), ankylosing spondylitis (men), AT (women), and BP (women) than controls.
Those aged under 40 years were more likely to develop AA, primary cicatricial alopecia, Behçet disease, and ulcerative colitis, while those aged 40 years or older were more likely to develop AA, AT, vitiligo, Behçet disease, Crohn’s disease, rheumatoid arthritis, systemic lupus erythematosus, Sjögren’s syndrome, ankylosing spondylitis, and BP.
Additionally, severe COVID-19 requiring intensive care unit admission was associated with a significantly increased risk for autoimmune diseases, including AA, psoriasis, BP, and sarcoidosis. By timeframe, risks for AA, AT, and psoriasis were significantly higher during the initial Delta-dominant period.
Vaccination Effect
Moreover, vaccinated individuals were less likely to develop AA, AT, psoriasis, Behçet disease, and various nondermatologic conditions than were those who were unvaccinated. This finding, wrote Heo and colleagues, “may provide evidence to support the hypothesis that COVID-19 vaccines can help prevent autoimmune diseases.”
“That’s the part we all need to take into our offices tomorrow,” said Brett King, MD, PhD, a Fairfield, Connecticut–based dermatologist in private practice. He was not involved with the study but was asked to comment.
Overall, King said, the study carries two main messages. “The first is that COVID-19 infection increases the likelihood of developing an autoimmune or autoinflammatory disease in a large population.” The second and very important message is that being vaccinated against COVID-19 provides protection against developing an autoimmune or autoinflammatory disease.
“My concern is that the popular media highlights the first part,” said King, “and everybody who develops alopecia areata, vitiligo, or sarcoidosis blames COVID-19. That’s not what this work says.”
The foregoing distinction is especially important during the fall and winter, he added, when people getting influenza vaccines are routinely offered COVID-19 vaccines. “Many patients have said, ‘I got the COVID vaccine and developed alopecia areata 6 months later.’ Nearly everybody who has developed a new or worsening health condition in the last almost 5 years has had the perfect fall guy — the COVID vaccine or infection.”
With virtually all patients asking if they should get an updated COVID-19 vaccine or booster, he added, many report having heard that such vaccines cause AA, vitiligo, or other diseases. “To anchor these conversations in real data and not just anecdotes from a blog or Facebook is very useful,” said King, “and now we have very good data saying that the COVID vaccine is protective against these disorders.”
George Han, MD, PhD, associate professor of dermatology at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell in Hempstead, New York, applauds investigators’ use of a large, robust database but suggests interpreting results cautiously. He was not involved with the study but was asked to comment.
“You could do a large, well-done study,” Han said, “but it could still not necessarily be generalizable. These autoimmune conditions they’re looking at have clear ethnic and racial biases.” Heo and colleagues acknowledged shortcomings including their study population’s monomorphic nature.
Additional issues that limit the study’s impact, said Han, include the difficulty of conceptualizing a 10%-20% increase in conditions that at baseline are rare. And many of the findings reflected natural patterns, he said. For instance, BP more commonly affects older people, COVID-19 notwithstanding.
Han said that for him, the study’s main value going forward is helping to explain a rash of worsening inflammatory skin disease that many dermatologists saw early in the pandemic. “We would regularly see patients who were well controlled with, for example, psoriasis or eczema. But after COVID-19 infection or a vaccine (usually mRNA-type), in some cases they would come in flaring badly.” This happened at least a dozen times during the first year of post-shutdown appointments, he said.
“We’ve seen patients who have flared multiple times — they get the booster, then flare again,” Han added. Similar patterns occurred with pyoderma gangrenosum and other inflammatory skin diseases, he said.
Given the modest effect sizes of the associations reported in the Korean study, Arkin and colleagues wrote in their JAMA Dermatology editorial that surveillance for autoimmune disease is probably not warranted without new examination findings or symptoms. “For certain,” King said, “we should not go hunting for things that aren’t obviously there.”
Rather, Arkin and colleagues wrote, the higher autoimmunity rates seen among the unvaccinated, as well as during the Delta phase (when patients were sicker and hospitalizations were more likely) and in patients requiring intensive care, suggest that “interventions that reduce disease severity could also potentially reduce long-term risk of subsequent autoimmune sequelae.”
Future research addressing whether people with preexisting autoimmune conditions are at greater risk for flares or developing new autoimmune diseases following COVID-19 infection “would help to frame an evidence-based approach for patients with autoimmune disorders who develop COVID-19 infection, including the role for antiviral treatments,” they added.
The study was supported by grants from the Research Program of the Korea Medical Institute, the Korea Health Industry Development Institute, and the National Research Foundation of Korea. Han and King reported no relevant financial relationships. Arkin disclosed receiving research grants to her institution from Amgen and Eli Lilly, personal fees from Sanofi/Regeneron for consulting, and personal consulting fees from Merck outside the submitted work. Another author reported personal consulting fees from Dexcel Pharma and Honeydew outside the submitted work. No other disclosures were reported.

Additionally, severe COVID-19 requiring intensive care unit admission was associated with a significantly increased risk for autoimmune diseases, including AA, psoriasis, BP, and sarcoidosis. By timeframe, risks for AA, AT, and psoriasis were significantly higher during the initial Delta-dominant period.
Vaccination Effect
Moreover, vaccinated individuals were less likely to develop AA, AT, psoriasis, Behçet disease, and various nondermatologic conditions than were those who were unvaccinated. This finding, wrote Heo and colleagues, “may provide evidence to support the hypothesis that COVID-19 vaccines can help prevent autoimmune diseases.”
“That’s the part we all need to take into our offices tomorrow,” said Brett King, MD, PhD, a Fairfield, Connecticut–based dermatologist in private practice. He was not involved with the study but was asked to comment.
Overall, King said, the study carries two main messages. “The first is that COVID-19 infection increases the likelihood of developing an autoimmune or autoinflammatory disease in a large population.” The second and very important message is that being vaccinated against COVID-19 provides protection against developing an autoimmune or autoinflammatory disease.
“My concern is that the popular media highlights the first part,” said King, “and everybody who develops alopecia areata, vitiligo, or sarcoidosis blames COVID-19. That’s not what this work says.”
The foregoing distinction is especially important during the fall and winter, he added, when people getting influenza vaccines are routinely offered COVID-19 vaccines. “Many patients have said, ‘I got the COVID vaccine and developed alopecia areata 6 months later.’ Nearly everybody who has developed a new or worsening health condition in the last almost 5 years has had the perfect fall guy — the COVID vaccine or infection.”
With virtually all patients asking if they should get an updated COVID-19 vaccine or booster, he added, many report having heard that such vaccines cause AA, vitiligo, or other diseases. “To anchor these conversations in real data and not just anecdotes from a blog or Facebook is very useful,” said King, “and now we have very good data saying that the COVID vaccine is protective against these disorders.”
George Han, MD, PhD, associate professor of dermatology at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell in Hempstead, New York, applauds investigators’ use of a large, robust database but suggests interpreting results cautiously. He was not involved with the study but was asked to comment.
“You could do a large, well-done study,” Han said, “but it could still not necessarily be generalizable. These autoimmune conditions they’re looking at have clear ethnic and racial biases.” Heo and colleagues acknowledged shortcomings including their study population’s monomorphic nature.
Additional issues that limit the study’s impact, said Han, include the difficulty of conceptualizing a 10%-20% increase in conditions that at baseline are rare. And many of the findings reflected natural patterns, he said. For instance, BP more commonly affects older people, COVID-19 notwithstanding.
Han said that for him, the study’s main value going forward is helping to explain a rash of worsening inflammatory skin disease that many dermatologists saw early in the pandemic. “We would regularly see patients who were well controlled with, for example, psoriasis or eczema. But after COVID-19 infection or a vaccine (usually mRNA-type), in some cases they would come in flaring badly.” This happened at least a dozen times during the first year of post-shutdown appointments, he said.
“We’ve seen patients who have flared multiple times — they get the booster, then flare again,” Han added. Similar patterns occurred with pyoderma gangrenosum and other inflammatory skin diseases, he said.
Given the modest effect sizes of the associations reported in the Korean study, Arkin and colleagues wrote in their JAMA Dermatology editorial that surveillance for autoimmune disease is probably not warranted without new examination findings or symptoms. “For certain,” King said, “we should not go hunting for things that aren’t obviously there.”
Rather, Arkin and colleagues wrote, the higher autoimmunity rates seen among the unvaccinated, as well as during the Delta phase (when patients were sicker and hospitalizations were more likely) and in patients requiring intensive care, suggest that “interventions that reduce disease severity could also potentially reduce long-term risk of subsequent autoimmune sequelae.”
Future research addressing whether people with preexisting autoimmune conditions are at greater risk for flares or developing new autoimmune diseases following COVID-19 infection “would help to frame an evidence-based approach for patients with autoimmune disorders who develop COVID-19 infection, including the role for antiviral treatments,” they added.
The study was supported by grants from the Research Program of the Korea Medical Institute, the Korea Health Industry Development Institute, and the National Research Foundation of Korea. Han and King reported no relevant financial relationships. Arkin disclosed receiving research grants to her institution from Amgen and Eli Lilly, personal fees from Sanofi/Regeneron for consulting, and personal consulting fees from Merck outside the submitted work. Another author reported personal consulting fees from Dexcel Pharma and Honeydew outside the submitted work. No other disclosures were reported.

In addition, the authors reported that COVID-19 vaccination appears to reduce these risks.

‘Compelling Evidence’
“This well-executed study by Heo et al provides compelling evidence to support an association between COVID-19 infection and the development of subsequent autoimmune and autoinflammatory skin diseases,” wrote authors led by Lisa M. Arkin, MD, of the Department of Dermatology, University of Wisconsin School of Medicine and Public Health in Madison, in an accompanying editorial.
Using databases from Korea’s National Health Insurance Service and the Korea Disease Control and Prevention Agency, investigators led by Yeon-Woo Heo, MD, a dermatology resident at Yonsei University Wonju College of Medicine, Wonju, Republic of Korea, compared 3.1 million people who had COVID-19 with 3.8 million controls, all with at least 180 days’ follow-up through December 31, 2022.
At a mean follow-up of 287 days in both cohorts, authors found significantly elevated risks for AA and vitiligo (adjusted hazard ratio [aHR], 1.11 for both), AT (aHR, 1.24), Behçet disease (aHR, 1.45), and BP (aHR, 1.62) in the post–COVID-19 cohort. The infection also raised the risk for other conditions such as systemic lupus erythematosus (aHR, 1.14) and Crohn’s disease (aHR, 1.35).
In subgroup analyses, demographic factors were associated with diverse effects: COVID-19 infection was associated with significantly higher odds of developing AA (for both men and women), vitiligo (men), Behçet disease (men and women), Crohn’s disease (men), ulcerative colitis (men), rheumatoid arthritis (men and women), systemic lupus erythematosus (men), ankylosing spondylitis (men), AT (women), and BP (women) than controls.
Those aged under 40 years were more likely to develop AA, primary cicatricial alopecia, Behçet disease, and ulcerative colitis, while those aged 40 years or older were more likely to develop AA, AT, vitiligo, Behçet disease, Crohn’s disease, rheumatoid arthritis, systemic lupus erythematosus, Sjögren’s syndrome, ankylosing spondylitis, and BP.

Expert Reviews Options for Revitalizing Dystrophic Nails
LAS VEGAS —
“With the fingernails, we don’t often see onychomycosis, but with toenails, we certainly do,” Tracey C. Vlahovic, DPM, a professor at the Samuel Merritt University College of Podiatric Medicine, Oakland, California, said at the Society of Dermatology Physician Associates (SDPA) 22nd Annual Fall Dermatology Conference. “But toenails are subject to a lot of forces beyond just fungal [infections]. We have the wear and tear of wearing shoes, gait, and other physical activity.”
For example, she continued, some runners develop second-toenail dystrophy “because there’s constant repetitive trauma to the toenail, and [poorly fitting] shoes can contribute to that. Biomechanical issues are a unique consideration when you’re dealing with toenail issues.”
Vlahovic highlighted several options that can help improve the appearance of dystrophic nails as they recover or grow back:
Urea nail preparations: To temporarily soften the nail.
Genadur (hydroxypropyl chitosan): This product “is used mainly for psoriatic nails, but I use it for all different kinds of nail dystrophy,” she said.
DermaNail (acetyl mandelic acid solution): This can be used for brittle nails and fingernails. Vlahovic said she recommends it be used on toenails “in addition to the onychomycosis and other nail dystrophy treatments that I’m doing because it really helps to hydrate the nail unit.”
Kerasal Fungal Nail Renewal (ingredients include propylene glycol, urea, glycerin, and lactic acid): This product is used “for smoothing out the appearance of the nail,” she said.
KeryFlex: Applied in an office setting, this resin-based product restores the appearance of an individual’s natural nails. “It comes in two colors [and] absorbs the shock of what is going on mechanically with the feet,” Vlahovic said. “So, if I’m treating a ballet dancer performing en pointe, or a soccer player, it’s something I can use to protect the nail, but also to make it cosmetically more acceptable.”
NECPro: A nail reconstruction method that involves the use of a composite used mainly by podiatrists, it “helps you not only create a barrier, but to create a natural-looking color that matches your own nail color,” she said.
In Vlahovic’s experience, KeryFlex and NECPro last 6-8 weeks. “You can use nail polish on top of them if you’d like, but they’re basically cosmetic barriers to protect the nail unit,” she said.
Vlahovic has disclosed being a consultant and investigator for Ortho Dermatologics and Sagis Diagnostics.

Study Finds No Significant Effect of Low-Dose Oral Minoxidil on BP
TOPLINE:
but is associated with a slight increase in heart rate and a 5% incidence of hypotensive symptoms.
METHODOLOGY:
- Researchers conducted a systematic review and meta-analysis of 16 studies, which involved 2387 patients with alopecia (60.7% women) who received minoxidil, a vasodilator originally developed as an antihypertensive, at doses of 5 mg or less per day.
- Outcomes included changes in mean arterial pressure, systolic BP, diastolic BP, and heart rate.
- Mean differences were calculated between pretreatment and posttreatment values.
TAKEAWAY:
- Hypotensive symptoms were reported in 5% patients, with no significant hypotensive episodes. About 1.8% patients experienced lightheadedness or syncope, 1.2% experienced dizziness, 0.9% had tachycardia, and 0.8% had palpitations.
- LDOM did not significantly alter systolic BP (mean difference, –0.13; 95% CI, –2.67 to 2.41), diastolic BP (mean difference, –1.25; 95% CI, –3.21 to 0.71), and mean arterial pressure (mean difference, –1.92; 95% CI, –4.00 to 0.17).
- LDOM led to a significant increase in heart rate (mean difference, 2.67 beats/min; 95% CI, 0.34-5.01), a difference the authors wrote would “likely not be clinically significant for most patients.”
- Hypertrichosis was the most common side effect (59.6%) and reason for stopping treatment (accounting for nearly 35% of discontinuations).
IN PRACTICE:
“LDOM appears to be a safe treatment for alopecia with no significant impact on blood pressure,” the authors wrote, noting that the study “addresses gaps in clinical knowledge involving LDOM.” Based on their results, they recommended that BP and heart rate “do not need to be closely monitored in patients without prior cardiovascular risk history.”
SOURCE:
The study was led by Matthew Chen, BS, Stony Brook Dermatology in New York. It was published online in The Journal of the American Academy of Dermatology.
LIMITATIONS:
The studies included had small sample sizes and retrospective designs, which may limit the reliability of the findings. Additional limitations include the absence of control groups, a potential recall bias in adverse effect reporting, and variability in dosing regimens and BP monitoring.
DISCLOSURES:
The authors reported no external funding or conflicts of interest.

Lichen Planus Responds to Treatment with Topical Ruxolitinib in Phase 2 Study
The research, presented at the European Academy of Dermatology and Venereology (EADV) 2024 Congress, involved 64 patients older than 18 years. Ruxolitinib cream (Opzelura) is a topical formulation of a Janus kinase (JAK)1/JAK2 inhibitor, approved by the Food and Drug Administration (FDA) for treating mild to moderate atopic dermatitis and for nonsegmental vitiligo in adults and children aged 12 years or older.
Ruxolitinib cream twice daily resulted in “significant improvements in cutaneous lichen planus disease severity vs vehicle” after 16 weeks of treatment, said the study presenter, Aaron R. Mangold, MD, a dermatologist at Mayo Clinic, Scottsdale, Arizona.
Further improvements were seen during another 16 weeks of additional open-label, as-needed application, he added, and the topical treatment was “generally well tolerated.”
Consequently, “ruxolitinib cream represents a promising potential treatment for cutaneous lichen planus,” Mangold concluded.
Asked to comment on the results, Adam Friedman, MD, Professor and Chair of Dermatology, George Washington University, Washington, DC, who was not involved with the study, said that in keeping with the characterization of lichen planus using the four Ps — purple, polygonal, pruritic, papules — it is “Pretty common, Predictably disabling and disfiguring, and Passed over again and again in the drug development world.”
He said in an interview that this chronic inflammatory skin condition, which affects roughly 2% of the population, also “lacks consensus on work-up and management, likely in part owing to the absence of sizable clinical trial data.”
A recent survey conducted at a meeting indicated that dermatologists “heavily lean on topical therapies for the management of all severity levels,” noted Friedman, one of the survey authors. “Therefore, the phase 2 data presented at EADV is a welcome addition to the mix.”
Phase 2 Study Results
At the meeting, Mangold said that a previous proof-of-concept single-arm study in 12 patients suggested that topical ruxolitinib was highly effective in treating cutaneous lichen planus.
The current phase 2 trial enrolled 64 patients with predominantly cutaneous disease who had an Investigator’s Global Assessment (IGA) score of 3 or 4 and an Itch Numeric Rating Scale (NRS) score of ≥ 4. Their median age was 57 years, and 71.9% were women. Nearly 63% were White, 28.1% were Black, and 6.3% were Asian. The median duration of disease was 4.9 years, and 90.6% had received prior treatment for their lichen planus.
They were randomized to receive 1.5% ruxolitinib cream or a vehicle cream twice daily for 16 weeks, and following a primary endpoint assessment, they were transferred to an open-label extension period, during which they used ruxolitinib cream as needed for another 16 weeks. There was an additional 30-day safety follow-up period.
At week 16, significantly more patients treated with the ruxolitinib cream (50.0%) vs vehicle cream (21.9%) achieved IGA treatment success (the primary endpoint), defined as an IGA score of 0 or 1 with ≥ 2-grade improvement from baseline (odds ratio, 4.04; P = .0129).
In the open-label extension, when all patients used the active cream as needed, the proportion achieving IGA treatment success increased to 60% among the patients originally treated with ruxolitinib cream and 60.9% among those who switched from the vehicle cream.
A similar pattern was seen with Itch NRS scores. At 16 weeks, 57.7% of those treated with the ruxolitinib cream and 19.2% of those given the vehicle cream achieved an Itch NRS score of ≥ 4 (P < .01), rising to 84.2% and 73.3%, respectively, during the open-label extension.
The time to achievement of an Itch NRS of ≥ 4 was also significantly shorter with the ruxolitinib cream than with the vehicle cream (median days, 17 vs 97; hazard ratio, 2.85; P = .0008).
In both treatment groups, Skin Pain NRS scores decreased by a mean of 3.0 with ruxolitinib cream and 1.3 with the vehicle cream at week 16. By the end of the open-label extension, scores dropped by 4.3 among those who continued on active treatment and by 3.5 among those who switched from vehicle to topical ruxolitinib.
There were few treatment-emergent adverse events, with just three ruxolitinib patients affected during the randomized phase of the trial. There was one grade ≥ 3 event considered unrelated to the study drug, and no serious treatment-emergent adverse events were reported.
The most common adverse events during the randomized period were nasopharyngitis, hypertension, and contusion, all experienced by fewer than 10% of patients, whereas sinusitis, increased blood cholesterol levels, and increased blood creatine phosphokinase were most common in the open-label extension, experienced by no more than 5% of patients.
In the interview, Friedman commented that “these data provide hope that one day soon, there will be an FDA-approved, effective, and well-tolerated approach for this condition, validating the patient and supporting the dermatologist with an evidence-based option.”
The study was funded by Incyte. Mangold declared relationships with Argenx, Boehringer Ingelheim, Bristol-Myers Squibb, Clarivate, Incyte Corporation, Janssen, Nuvig Therapeutics, Pfizer, Regeneron Pharmaceuticals, Soligenix, Tourmaline Bio, AbbVie, Corbus, Eli Lilly, Kyowa, Merck, miRagen Therapeutics, Palvella Therapeutics, Priovant Therapeutics, and Adelphi Values. Friedman declared a relationship with Incyte, but it is not related to this topic.

Ruxolitinib cream (Opzelura) is a topical formulation of a Janus kinase (JAK)1/JAK2 inhibitor, approved by the Food and Drug Administration (FDA) for treating mild to moderate atopic dermatitis and for nonsegmental vitiligo in adults and children aged 12 years or older.
Ruxolitinib cream twice daily resulted in “significant improvements in cutaneous lichen planus disease severity vs vehicle” after 16 weeks of treatment, said the study presenter, Aaron R. Mangold, MD, a dermatologist at Mayo Clinic, Scottsdale, Arizona.
Further improvements were seen during another 16 weeks of additional open-label, as-needed application, he added, and the topical treatment was “generally well tolerated.”
Consequently, “ruxolitinib cream represents a promising potential treatment for cutaneous lichen planus,” Mangold concluded.
Asked to comment on the results, Adam Friedman, MD, Professor and Chair of Dermatology, George Washington University, Washington, DC, who was not involved with the study, said that in keeping with the characterization of lichen planus using the four Ps — purple, polygonal, pruritic, papules — it is “Pretty common, Predictably disabling and disfiguring, and Passed over again and again in the drug development world.”
He said in an interview that this chronic inflammatory skin condition, which affects roughly 2% of the population, also “lacks consensus on work-up and management, likely in part owing to the absence of sizable clinical trial data.”
A recent survey conducted at a meeting indicated that dermatologists “heavily lean on topical therapies for the management of all severity levels,” noted Friedman, one of the survey authors. “Therefore, the phase 2 data presented at EADV is a welcome addition to the mix.”
Phase 2 Study Results
At the meeting, Mangold said that a previous proof-of-concept single-arm study in 12 patients suggested that topical ruxolitinib was highly effective in treating cutaneous lichen planus.
The current phase 2 trial enrolled 64 patients with predominantly cutaneous disease who had an Investigator’s Global Assessment (IGA) score of 3 or 4 and an Itch Numeric Rating Scale (NRS) score of ≥ 4. Their median age was 57 years, and 71.9% were women. Nearly 63% were White, 28.1% were Black, and 6.3% were Asian. The median duration of disease was 4.9 years, and 90.6% had received prior treatment for their lichen planus.
They were randomized to receive 1.5% ruxolitinib cream or a vehicle cream twice daily for 16 weeks, and following a primary endpoint assessment, they were transferred to an open-label extension period, during which they used ruxolitinib cream as needed for another 16 weeks. There was an additional 30-day safety follow-up period.
At week 16, significantly more patients treated with the ruxolitinib cream (50.0%) vs vehicle cream (21.9%) achieved IGA treatment success (the primary endpoint), defined as an IGA score of 0 or 1 with ≥ 2-grade improvement from baseline (odds ratio, 4.04; P = .0129).
In the open-label extension, when all patients used the active cream as needed, the proportion achieving IGA treatment success increased to 60% among the patients originally treated with ruxolitinib cream and 60.9% among those who switched from the vehicle cream.
A similar pattern was seen with Itch NRS scores. At 16 weeks, 57.7% of those treated with the ruxolitinib cream and 19.2% of those given the vehicle cream achieved an Itch NRS score of ≥ 4 (P < .01), rising to 84.2% and 73.3%, respectively, during the open-label extension.
The time to achievement of an Itch NRS of ≥ 4 was also significantly shorter with the ruxolitinib cream than with the vehicle cream (median days, 17 vs 97; hazard ratio, 2.85; P = .0008).
In both treatment groups, Skin Pain NRS scores decreased by a mean of 3.0 with ruxolitinib cream and 1.3 with the vehicle cream at week 16. By the end of the open-label extension, scores dropped by 4.3 among those who continued on active treatment and by 3.5 among those who switched from vehicle to topical ruxolitinib.
There were few treatment-emergent adverse events, with just three ruxolitinib patients affected during the randomized phase of the trial. There was one grade ≥ 3 event considered unrelated to the study drug, and no serious treatment-emergent adverse events were reported.
The most common adverse events during the randomized period were nasopharyngitis, hypertension, and contusion, all experienced by fewer than 10% of patients, whereas sinusitis, increased blood cholesterol levels, and increased blood creatine phosphokinase were most common in the open-label extension, experienced by no more than 5% of patients.
In the interview, Friedman commented that “these data provide hope that one day soon, there will be an FDA-approved, effective, and well-tolerated approach for this condition, validating the patient and supporting the dermatologist with an evidence-based option.”
The study was funded by Incyte. Mangold declared relationships with Argenx, Boehringer Ingelheim, Bristol-Myers Squibb, Clarivate, Incyte Corporation, Janssen, Nuvig Therapeutics, Pfizer, Regeneron Pharmaceuticals, Soligenix, Tourmaline Bio, AbbVie, Corbus, Eli Lilly, Kyowa, Merck, miRagen Therapeutics, Palvella Therapeutics, Priovant Therapeutics, and Adelphi Values. Friedman declared a relationship with Incyte, but it is not related to this topic.

FROM EADV 2024
Alopecia Induced by Poly-L-Lactic Acid Injection
Cosmetic procedures carry inherent risks of adverse events. Transient and permanent alopecia are rare complications of these procedures. Although they have not been fully elucidated, several pathologic mechanisms for hair loss following cosmetic procedures have been proposed, including extravascular compression (a phenomenon that has been well documented in bedridden patients) as well as intravascular occlusion leading to inflammation and necrosis, which has been associated with hyaluronic acid (HA) fillers.¹ Cases of alopecia also have been reported following mesotherapy and calcium hydroxyapatite, deoxycholic acid, and botulinum toxin injections.² We report a case of alopecia resulting from poly-L-lactic acid (PLLA) injection in a 35-year-old woman with the intent to raise awareness of this rare adverse event.
Case Report
A healthy 35-year-old woman received aesthetic PLLA injections on the face and frontal hairline performed by an outside dermatologist using the vector technique. During the procedure, the patient experienced intense itchiness at the right temporal artery vascular territory and reported a substantial headache the next day. She also presented with erythema and edema of the frontal and right parietal scalp with a well-delimited livedoid vascular area along the temporal artery territory on the right side of the head 1 day after the procedure (Figure 1). These signs were reported to the outside dermatologist who performed the procedure, but they were not assumed to be adverse events at that time.
The condition persisted for 4 days followed by the development of an irregular 3×2-cm patch of alopecia on the right parietal scalp. A 3-day course of self-administered oral prednisolone 0.2 mg/kg/d was prescribed.
Twenty-seven days after the procedure, the patient presented to our trichology clinic for evaluation of a single patch of nonscarring alopecia on the right parietal scalp. Trichoscopy showed multiple yellow and black dots, broken hairs, pigment deposits, and an erythematous background mainly composed of linear telangiectatic vessels (Figure 2). Histopathologic analysis revealed a lymphocytic inflammatory infiltrate surrounding the follicular units that was compatible with an alopecia areata–like pattern as well as PLLA deposits in the subcutaneous tissue forming foreign body granulomas (Figure 3). The diagnosis of PLLA-induced alopecia was made based on the detection of PLLA at the biopsy site within the patchy alopecia.
Intralesional triamcinolone acetonide 5 mg/mL was administered at 1-cm intervals in the subdermal space (0.1 mL/puncture site). After 14 days, the patient developed an additional patch of alopecia in the same vascular territory as the right temporal artery, positioned just beneath the initial patch, with similar trichoscopy findings. The patches were treated with intralesional triamcinolone acetonide for 3 additional sessions, administered every 4 weeks. Long-term monitoring of the patient revealed regrowth with comparable hair count to the unaffected contralateral scalp, indicative of a nonscarring alopecia.
Comment
Poly-L-lactic acid is a biostimulator synthesized from the α-hydroxy acid family in 1954 that has been safely used in suture materials, resorbable plates, and orthopedic screws.4 Alopecia has been reported as a systemic allergic reaction to biodegradable screws following an orthopedic procedure.5 Prior reports of embolization and retinal ischemia with PLLA have raised concerns regarding its occlusive potential.6-9
Approved by the US Food and Drug Administration in 2004 for soft tissue restoration in HIV-related lipoatrophy, PLLA was expanded to cosmetic applications in 2009. As previously reported with HA fillers, we hypothesize that extravascular compression resulting from the placement of the filler material (due to the volume injected in the scalp area) contributes to the development of alopecia plus PLLA embolism–induced ischemic alopecia in the affected areas.10 In our case, the diagnosis of PLLA-induced alopecia was confirmed based on the finding of the filler material in the subcutaneous tissue on histopathology, probably due to embolization. Moreover, trichoscopic findings were all similar to those described after HA embolization.11 The features found in our patient due to the PLLA local reaction were similar to those seen in other conditions such as alopecia areata, pressure alopecia, and chemotherapy-induced alopecia; therefore, histopathology confirmation is mandatory in cases of hair loss associated with PLLA.
The emergence of a secondary patch of alopecia prompts consideration of an intrinsic late inflammatory propensity of PLLA. Immune cells recognize PLLA as a foreign body, and subclinical inflammatory foreign body reactions can cause PLLA-induced collagen synthesis.12 This phenomenon underscores the need for further investigation into the immunologic implications of PLLA in alopecia pathogenesis.
The angiogenic properties of the anagen phase require an adequate blood supply for effective hair growth; therefore, the lack of blood and nutrient supply to the hair bulb triggers miniaturization, a possible explanation for the hair thinning found in the alopecic patch.13
Conclusion
Alopecia as an adverse effect of cosmetic procedures can be distressing for patients, even when reversible. A detailed understanding of scalp anatomy is critical for satisfactory outcomes with aesthetic procedures. Physicians must pay attention to the amount and area of material injected in order to avoid possible mechanisms of ischemia—embolization and/or extravascular compression—especially in highly vascularized areas.
We present a rare report of alopecia as an adverse event of PLLA injection. Dermatologists must be aware of this rare condition, and trichoscopy combined with histopathologic analysis are encouraged for early recognition and proper management.

Practice Points
- Alopecia is a potential adverse event of poly-L-lactic acid (PLLA) injection, and prior reports of embolization and retinal ischemia with PLLA use raise the concern of its occlusive potential.
- The combination of extravascular compression due to the presence of the filler material in the subcutaneous tissue as well as intravascular PLLA embolism may contribute to tissue ischemia–induced alopecia in the affected areas.
- Poly-L-lactic acid also may cause a local inflammatory reaction that is alopecia areata–like, which would explain its similar trichoscopy findings.
Longitudinal Depression on the Right Thumbnail
THE DIAGNOSIS: Habit-Tic Deformity
Habit-tic deformity is a cause of nail dystrophy that commonly arises in children and adults due to subconscious repetitive and self-injurious manipulation of the nail bed or cuticle, which ultimately damages the nail matrix.1,2 It can be considered a variant of onychotillomania.1
Characteristic features of habit-tic deformity include a longitudinal depression on the central nail plate with transverse ridges,1 which can be more prominent on the dominant hand.3 Patients typically note a long duration of nail deformity, often without insight into its etiology.2 Diagnosis relies on careful assessment of the clinical presentation and the patient’s history to rule out other differential diagnoses. Based on our patient’s clinical presentation and history, we excluded wart, squamous cell carcinoma, eczema, psoriasis, lichen planus, autoimmune connective tissue disease, onychomycosis, paronychia, pincer nail deformity, and Beau line as potential diagnoses. Biopsy also can be performed to exclude these diagnoses from the differential if the cause is unclear following clinical examination.
Treatment for habit-tic deformity involves identifying and addressing the underlying habit. Barrier methods such as bandages and cyanoacrylate adhesives that prevent further manipulation of the nail matrix are effective treatments for habit-tic deformity.2 A multidisciplinary approach with psychiatry may be optimal to identify underlying psychological comorbidities and break the habit through behavior interventions and medications.4 Nail dystrophy generally improves once the habit is disrupted; however, a younger age of onset may carry a worse prognosis.3 Patients should be counseled that the affected nail may never grow normally.
Our patient was advised to use fluocinonide ointment 0.05% to reduce inflammation of the proximal nail fold and to cover the thumbnail with a bandage to prevent picking. He also was counseled that the nail may show ongoing abnormal growth. Minimal improvement was noted after 6 months.

A healthy 13-year-old boy presented to the dermatology department with dystrophy of the right thumbnail of 3 to 4 years’ duration. A 5-mm-wide, depressed median longitudinal groove with a fir tree pattern was noted on the central nail plate. The patient noted that the groove had been gradually deepening. There was erythema, edema, and lichenification of the proximal nailfold without vascular changes, and the lunula was enlarged. No hyperkeratosis, subungual debris, erythematous nail folds, or inward curvature of the lateral aspects of the nail were noted. The patient denied any pruritus, pain, discomfort, or bleeding; he also denied any recent illness or trauma to the nail. None of the other nails were affected, and no other lesions or rashes were observed elsewhere on the body. The patient was unsure if he picked at the nail but acknowledged that he may have done so subconsciously. He had no history of eczema, psoriasis, or autoimmune connective tissue disorders.
Sea Buckthorn
A member of the Elaeagnaceae family, Hippophae rhamnoides, better known as sea buckthorn, is a high-altitude wild shrub endemic to Europe and Asia with edible fruits and a lengthy record of use in traditional Chinese medicine.1-6 Used as a health supplement and consumed in the diet throughout the world,5 sea buckthorn berries, seeds, and leaves have been used in traditional medicine to treat burns/injuries, edema, hypertension, inflammation, skin grafts, ulcers, and wounds.4,7
This hardy plant is associated with a wide range of biologic activities, including anti-atherogenic, anti-atopic dermatitis, antibacterial, anticancer, antifungal, anti-inflammatory, antimicrobial, antioxidant, anti-psoriasis, anti-sebum, anti-stress, anti-tumor, cytoprotective, hepatoprotective, immunomodulatory, neuroprotective, radioprotective, and tissue regenerative functions.4,5,8-11
Key Constituents
Functional constituents identified in sea buckthorn include alkaloids, carotenoids, flavonoids, lignans, organic acids, phenolic acids, proanthocyanidins, polyunsaturated acids (including omega-3, -6, -7, and -9), steroids, tannins, terpenoids, and volatile oils, as well as nutritional compounds such as minerals, proteins, and vitamins.4,5,11 Sea buckthorn pericarp oil contains copious amounts of saturated palmitic acid (29%-36%) and omega-7 unsaturated palmitoleic acid (36%-48%), which fosters cutaneous and mucosal epithelialization, as well as linoleic (10%-12%) and oleic (4%-6%) acids.12,6 Significant amounts of carotenoids as well as alpha‐linolenic fatty acid (38%), linoleic (36%), oleic (13%), and palmitic (7%) acids are present in sea buckthorn seed oil.6
Polysaccharides
In an expansive review on the pharmacological activities of sea buckthorn polysaccharides, Teng and colleagues reported in April 2024 that 20 diverse polysaccharides have been culled from sea buckthorn and exhibited various healthy activities, including antioxidant, anti-fatigue, anti-inflammatory, anti-obesity, anti-tumor, hepatoprotective, hypoglycemic, and immunoregulation, and regulation of intestinal flora activities.1
Proanthocyanidins and Anti-Aging
In 2023, Liu and colleagues investigated the anti–skin aging impact of sea buckthorn proanthocyanidins in D-galactose-induced aging in mice given the known free radical scavenging activity of these compounds. They found the proanthocyanidins mitigated D-galactose-induced aging and can augment the total antioxidant capacity of the body. Sea buckthorn proanthocyanidins can further attenuate the effects of skin aging by regulating the TGF-beta1/Smads pathway and MMPs/TIMP system, thus amplifying collagen I and tropoelastin content.13
A year earlier, many of the same investigators assessed the possible protective activity of sea buckthorn proanthocyanidins against cutaneous aging engendered by oxidative stress from hydrogen peroxide. The compounds amplified superoxide dismutase and glutathione antioxidant functions. The extracts also fostered collagen I production in aging human skin fibroblasts via the TGF-beta1/Smads pathway and hindered collagen I degradation by regulating the MMPs/TIMPs system, which maintained extracellular matrix integrity. Senescent cell migration was also promoted with 100 mcg/mL of sea buckthorn proanthocyanidins. The researchers concluded that this sets the stage for investigating how sea buckthorn proanthocyanidins can be incorporated in cosmetic formulations.14 In a separate study, Liu and colleagues demonstrated that sea buckthorn proanthocyanidins can attenuate oxidative damage and protect mitochondrial function.9
Acne and Barrier Functions
The extracts of H rhamnoides and Cassia fistula in a combined formulation were found to be effective in lowering skin sebum content in humans with grade I and grade II acne vulgaris in a 2014 single-blind, randomized, placebo-controlled, split-face study with two groups of 25 patients each (aged 18-37 years).15 Khan and colleagues have also reported that a sea buckthorn oil-in-water emulsion improved barrier function in human skin as tested by a tewameter and corneometer (noninvasive probes) in 13 healthy males with a mean age of 27 ± 4.8 years.16
Anti-Aging, Antioxidant, Antibacterial, Skin-Whitening Activity
Zaman and colleagues reported in 2011 that results from an in vivo study of the effects of a sea buckthorn fruit extract topical cream on stratum corneum water content and transepidermal water loss indicated that the formulation enhanced cell surface integrin expression thus facilitating collagen contraction.17
In 2012, Khan and colleagues reported amelioration in skin elasticity, thus achieving an anti-aging result, from the use of a water-in-oil–based hydroalcoholic cream loaded with fruit extract of H rhamnoides, as measured with a Cutometer.18 The previous year, some of the same researchers reported that the antioxidants and flavonoids found in a topical sea buckthorn formulation could decrease cutaneous melanin and erythema levels.
More recently, Gęgotek and colleagues found that sea buckthorn seed oil prevented redox balance and lipid metabolism disturbances in skin fibroblasts and keratinocytes caused by UVA or UVB. They suggested that such findings point to the potential of this natural agent to confer anti-inflammatory properties and photoprotection to the skin.19
In 2020, Ivanišová and colleagues investigated the antioxidant and antimicrobial activities of H rhamnoides 100% oil, 100% juice, dry berries, and tea (dry berries, leaves, and twigs). They found that all of the studied sea buckthorn products displayed high antioxidant activity (identified through DPPH radical scavenging and molybdenum reducing antioxidant power tests). Sea buckthorn juice contained the highest total content of polyphenols, flavonoids, and carotenoids. All of the tested products also exhibited substantial antibacterial activity against the tested microbes.20
Burns and Wound Healing
In a preclinical study of the effects of sea buckthorn leaf extracts on wound healing in albino rats using an excision-punch wound model in 2005, Gupta and colleagues found that twice daily topical application of the aqueous leaf extract fostered wound healing. This was indicated by higher hydroxyproline and protein levels, a diminished wound area, and lower lipid peroxide levels. The investigators suggested that sea buckthorn may facilitate wound healing at least in part because of elevated antioxidant activity in the granulation tissue.3
A year later, Wang and colleagues reported on observations of using H rhamnoides oil, a traditional Chinese herbal medicine derived from sea buckthorn fruit, as a burn treatment. In the study, 151 burn patients received an H rhamnoides oil dressing (changed every other day until wound healing) that was covered with a disinfecting dressing. The dressing reduced swelling and effusion, and alleviated pain, with patients receiving the sea buckthorn dressing experiencing greater apparent exudation reduction, pain reduction, and more rapid epithelial cell growth and wound healing than controls (treated only with Vaseline gauze). The difference between the two groups was statistically significant.21
Conclusion
Sea buckthorn has been used for hundreds if not thousands of years in traditional medical applications, including for dermatologic purposes. Emerging data appear to support the use of this dynamic plant for consideration in dermatologic applications. As is often the case, much more work is necessary in the form of randomized controlled trials to determine the effectiveness of sea buckthorn formulations as well as the most appropriate avenues of research or uses for dermatologic application of this traditionally used botanical agent.

A member of the Elaeagnaceae family, Hippophae rhamnoides, better known as sea buckthorn, is a high-altitude wild shrub endemic to Europe and Asia with edible fruits and a lengthy record of use in traditional Chinese medicine.1-6 Used as a health supplement and consumed in the diet throughout the world,5 sea buckthorn berries, seeds, and leaves have been used in traditional medicine to treat burns/injuries, edema, hypertension, inflammation, skin grafts, ulcers, and wounds.4,7
This hardy plant is associated with a wide range of biologic activities, including anti-atherogenic, anti-atopic dermatitis, antibacterial, anticancer, antifungal, anti-inflammatory, antimicrobial, antioxidant, anti-psoriasis, anti-sebum, anti-stress, anti-tumor, cytoprotective, hepatoprotective, immunomodulatory, neuroprotective, radioprotective, and tissue regenerative functions.4,5,8-11
Key Constituents
Functional constituents identified in sea buckthorn include alkaloids, carotenoids, flavonoids, lignans, organic acids, phenolic acids, proanthocyanidins, polyunsaturated acids (including omega-3, -6, -7, and -9), steroids, tannins, terpenoids, and volatile oils, as well as nutritional compounds such as minerals, proteins, and vitamins.4,5,11 Sea buckthorn pericarp oil contains copious amounts of saturated palmitic acid (29%-36%) and omega-7 unsaturated palmitoleic acid (36%-48%), which fosters cutaneous and mucosal epithelialization, as well as linoleic (10%-12%) and oleic (4%-6%) acids.12,6 Significant amounts of carotenoids as well as alpha‐linolenic fatty acid (38%), linoleic (36%), oleic (13%), and palmitic (7%) acids are present in sea buckthorn seed oil.6
Polysaccharides
In an expansive review on the pharmacological activities of sea buckthorn polysaccharides, Teng and colleagues reported in April 2024 that 20 diverse polysaccharides have been culled from sea buckthorn and exhibited various healthy activities, including antioxidant, anti-fatigue, anti-inflammatory, anti-obesity, anti-tumor, hepatoprotective, hypoglycemic, and immunoregulation, and regulation of intestinal flora activities.1
Proanthocyanidins and Anti-Aging
In 2023, Liu and colleagues investigated the anti–skin aging impact of sea buckthorn proanthocyanidins in D-galactose-induced aging in mice given the known free radical scavenging activity of these compounds. They found the proanthocyanidins mitigated D-galactose-induced aging and can augment the total antioxidant capacity of the body. Sea buckthorn proanthocyanidins can further attenuate the effects of skin aging by regulating the TGF-beta1/Smads pathway and MMPs/TIMP system, thus amplifying collagen I and tropoelastin content.13
A year earlier, many of the same investigators assessed the possible protective activity of sea buckthorn proanthocyanidins against cutaneous aging engendered by oxidative stress from hydrogen peroxide. The compounds amplified superoxide dismutase and glutathione antioxidant functions. The extracts also fostered collagen I production in aging human skin fibroblasts via the TGF-beta1/Smads pathway and hindered collagen I degradation by regulating the MMPs/TIMPs system, which maintained extracellular matrix integrity. Senescent cell migration was also promoted with 100 mcg/mL of sea buckthorn proanthocyanidins. The researchers concluded that this sets the stage for investigating how sea buckthorn proanthocyanidins can be incorporated in cosmetic formulations.14 In a separate study, Liu and colleagues demonstrated that sea buckthorn proanthocyanidins can attenuate oxidative damage and protect mitochondrial function.9
Acne and Barrier Functions
The extracts of H rhamnoides and Cassia fistula in a combined formulation were found to be effective in lowering skin sebum content in humans with grade I and grade II acne vulgaris in a 2014 single-blind, randomized, placebo-controlled, split-face study with two groups of 25 patients each (aged 18-37 years).15 Khan and colleagues have also reported that a sea buckthorn oil-in-water emulsion improved barrier function in human skin as tested by a tewameter and corneometer (noninvasive probes) in 13 healthy males with a mean age of 27 ± 4.8 years.16
Anti-Aging, Antioxidant, Antibacterial, Skin-Whitening Activity
Zaman and colleagues reported in 2011 that results from an in vivo study of the effects of a sea buckthorn fruit extract topical cream on stratum corneum water content and transepidermal water loss indicated that the formulation enhanced cell surface integrin expression thus facilitating collagen contraction.17
In 2012, Khan and colleagues reported amelioration in skin elasticity, thus achieving an anti-aging result, from the use of a water-in-oil–based hydroalcoholic cream loaded with fruit extract of H rhamnoides, as measured with a Cutometer.18 The previous year, some of the same researchers reported that the antioxidants and flavonoids found in a topical sea buckthorn formulation could decrease cutaneous melanin and erythema levels.
More recently, Gęgotek and colleagues found that sea buckthorn seed oil prevented redox balance and lipid metabolism disturbances in skin fibroblasts and keratinocytes caused by UVA or UVB. They suggested that such findings point to the potential of this natural agent to confer anti-inflammatory properties and photoprotection to the skin.19
In 2020, Ivanišová and colleagues investigated the antioxidant and antimicrobial activities of H rhamnoides 100% oil, 100% juice, dry berries, and tea (dry berries, leaves, and twigs). They found that all of the studied sea buckthorn products displayed high antioxidant activity (identified through DPPH radical scavenging and molybdenum reducing antioxidant power tests). Sea buckthorn juice contained the highest total content of polyphenols, flavonoids, and carotenoids. All of the tested products also exhibited substantial antibacterial activity against the tested microbes.20
Burns and Wound Healing
In a preclinical study of the effects of sea buckthorn leaf extracts on wound healing in albino rats using an excision-punch wound model in 2005, Gupta and colleagues found that twice daily topical application of the aqueous leaf extract fostered wound healing. This was indicated by higher hydroxyproline and protein levels, a diminished wound area, and lower lipid peroxide levels. The investigators suggested that sea buckthorn may facilitate wound healing at least in part because of elevated antioxidant activity in the granulation tissue.3
A year later, Wang and colleagues reported on observations of using H rhamnoides oil, a traditional Chinese herbal medicine derived from sea buckthorn fruit, as a burn treatment. In the study, 151 burn patients received an H rhamnoides oil dressing (changed every other day until wound healing) that was covered with a disinfecting dressing. The dressing reduced swelling and effusion, and alleviated pain, with patients receiving the sea buckthorn dressing experiencing greater apparent exudation reduction, pain reduction, and more rapid epithelial cell growth and wound healing than controls (treated only with Vaseline gauze). The difference between the two groups was statistically significant.21
Conclusion
Sea buckthorn has been used for hundreds if not thousands of years in traditional medical applications, including for dermatologic purposes. Emerging data appear to support the use of this dynamic plant for consideration in dermatologic applications. As is often the case, much more work is necessary in the form of randomized controlled trials to determine the effectiveness of sea buckthorn formulations as well as the most appropriate avenues of research or uses for dermatologic application of this traditionally used botanical agent.

ICD-10-CM Codes for CCCA, FFA Now Available
in the field of hair loss disorders.
“CCCA and FFA are conditions that require early diagnosis and intervention to prevent irreversible hair loss,” Maria Hordinsky, MD, professor of dermatology at the University of Minnesota, Minneapolis, and a member of the Board of Directors, Scarring Alopecia Foundation (SAF), said in an interview.
“The use of these new codes will make it easier for clinicians to identify affected patients and improve treatment outcomes. It also opens the door for more robust research efforts aimed at understanding the etiology and progression of CCCA and FFA, which could lead to new and more effective treatments in the future. Overall, this development represents a positive step toward improving care for individuals affected by these challenging conditions.”
The new codes — L66.81 for CCCA and L66.12 for FFA — were approved by the Centers for Disease Control and Prevention (CDC) on June 15, 2023, but not implemented until October 1, 2024.
Amy J. McMichael, MD, professor of dermatology at Wake Forest University School of Medicine, Winston-Salem, North Carolina, and a scientific advisor to SAF, told this news organization that Itisha Jefferson, a medical student at Loyola University Chicago’s Stritch School of Medicine, and her peers on the SAF’s Medical Student Executive Board, played a pivotal role in advocating for the codes.
In 2022, Jefferson, who has CCCA, and her fellow medical students helped create the proposals that were ultimately submitted to the CDC.
“They were critical in working with the CDC leaders to get the necessary information submitted and processed,” McMichael said. “They were also amazing at corralling our dermatologist group for the development of the necessary presentations and helped to shepherd us to the finish line for all logistic issues.”
On March 8, 2023, McMichael and Hordinsky made their pitch for the codes in person at the CDC’s ICD-10 Coordination and Maintenance Committee meeting, with McMichael discussing CCCA and Hordinsky discussing FFA.
“We also discussed the lack of standardized tracking, which has contributed to misdiagnoses and inadequate treatment options,” Hordinsky recalled. “We highlighted the importance of having distinct codes for these conditions to improve clinical outcomes, ensure that patients have access to appropriate care, better tracking of disease prevalence, and greater epidemiologic monitoring with access to electronic medical records and other large real-world evidence datasets and databases, the results of which could contribute to health policy decision-making.”
To spread the word about the new codes, McMichael, Hordinsky, and other members of the SAF are working with the original team of medical students, some of whom who are now dermatology residents, to develop an information guide to send to societies and organizations that were supportive of the codes. A publication in the dermatology literature is also planned.
For her part, Jefferson said that she will continue to advocate for patients with scarring alopecia as a medical student and when she becomes a physician. “I hope in the near future we will see an externally led FDA Patient-Focused Drug Development meeting for both CCCA and FFA, further advancing care and research for these conditions,” she said in an interview.
McMichael, Hordinsky, and Jefferson had no relevant disclosures to report.
