Onion Extract With SPF 30 Reduces Scars
SAN FRANCISCO A cream containing an onion extract and UVA and UVB sun protection significantly improves the appearance and feel of postsurgical scars, a small randomized trial found.
Nonprescription Mederma cream plus SPF 30 performed in the study comparably to Mederma onion extract gel without SPF for reduction of postsurgical scarring. Additionally, patients rated the cream as significantly more soothing than Mederma gel, Dr. Zoe D. Draelos reported at the annual meeting of the American Academy of Dermatology.
No placebo arm was included in the comparative trial because the study aim was to establish whether parity exists between the two onion extract formulations, both marketed OTC by Merz Pharmaceuticals, which sponsored the study. The gel formulation, which doesn't include sun protection, had already demonstrated superiority to placebo in an earlier randomized trial conducted by Dr. Draelos (J. Cosmet. Dermatol. 2008;7:101-4).
The new trial involved 20 patients with symmetric seborrheic keratoses at least 8 mm in diameter located on their right and left upper chest. The lesions were removed with a scalpel shave under local anesthesia. After the wound sites were permitted to heal for 2 weeks, patients returned for randomization. Three times daily for 8 weeks, they put a thin layer of the onion extract cream on the right chest scar and a layer of gel on the left chest scar, or vice versa, explained Dr. Draelos, who practices in High Point, N.C.
Blinded investigator assessment of the scars documented by photography showed significant improvement over time on 4-point scales assessing scar redness, texture, softness, and global appearance. The degree of improvement was similar for onion extract cream- and gel-treated scars.
There was also significantly less transepidermal water loss at the onion extract cream-treated excision sites than the gel-treated sites after treatment, probably because of the moisturizing base in the cream vehicle.
The therapeutic basis for the onion extract product's efficacy is believed to lie in its anti-inflammatory effects and its inhibition of fibroblast proliferation. The SPF 30 sun protection was incorporated into the cream formulation because scars are sunlight sensitive, and once they sunburn they often darken and become cosmetically unacceptable, she explained.
Dr. Draelos disclosed that she is a consultant to Merz and has been paid to conduct research for numerous pharmaceutical companies.

New Studies Support Eyelash Lengthener
MAUI, HAWAII Two studies have further demonstrated the safety and efficacy of bimatoprost for increased eyelash growth.
The Food and Drug Administration approved bimatoprost for increasing eyelash growth, a side effect of the glaucoma-treating drug that was observed several years ago.
In the first study presented at the annual Hawaii dermatology seminar sponsored by Skin Disease Education Foundation, Dr. David Wirta, an ophthalmologist in private practice in Newport Beach, Calif., and colleagues, conducted a safety analysis of bimatoprost based on the aggregated profile of six double-blind, active-controlled, long-term clinical studies.
Of the 1,459 patients treated with bimatoprost 0.03% once or twice daily for glaucoma, approximately 10% reported side effects that were of mild severity and led to a low study-discontinuation rate. The most commonly reported adverse effects were conjunctival hyperemia, eye pruritus, dry eye, eyelash growth, and skin hyperpigmentation.
In the second study, Dr. Wendy W. Lee and colleagues reported that bimatoprost increased eyelash growth by 2.01 mm in treated eyes, compared with 1.13 mm in controls. The patients reported no change in visual acuity or iris discoloration. The study patients received two vials of gel suspension, one containing bimatoprost and the other containing saline. The vials' contents were each mixed with 1:1 hypromellose solution and labeled "right eye" and "left eye." The suspensions were applied to the lashes once daily, each on the designated eye, for 6 weeks. Lashes were measured with a caliper at enrollment and at 1 and 3 months, according to Dr. Lee, assistant professor of clinical ophthalmology at the University of Miami.
The new indication for bimatoprost 0.03% ophthalmic solution is for "the treatment of hypotrichosis of the eyelashes by increasing their growth including length, thickness, and darkness." It is being marketed as Latisse by Allergan Inc. SDEFand this newspaper are owned by Elsevier.

Botox Still Tops Cosmetic Procedure List
The number of cosmetic medical procedures performed in the United States last year increased slightly because of growing demand for minimally invasive procedures like Botox and laser skin resurfacing, according to data from the American Society of Plastic Surgeons.
Despite the faltering economy, Americans opted for nearly 12.1 million cosmetic medical procedures last year, up 3% from 2007. That 3% rise, however, was the smallest increase recorded in cosmetic procedures since 2000. Popular surgical procedures such as liposuction and breast augmentation had double-digit decreases in the percentage of procedures performed in 2008. Overall, Americans spent $10.3 billion on cosmetic procedures last year, down 9% from 2007.
Botox continues to be the most popular cosmetic procedure in the United States, with more than 5 million procedures performed last year, up 8% from 2007. The number of procedures performed with hyaluronic acid fillers increased from about 1 million to 1.1 million, a 6% increase. The number of laser skin resurfacing procedures jumped 15% from 2007 to 2008, rising to more than 400,000 procedures, but microdermabrasion fell somewhat in 2008. The number of microdermabrasion procedures was down 6%, to about 841,000.
It seems that the most effective procedures, such as Botox and fillers, are increasing, while interest in less effective procedures like microdermabrasion is dropping, said Dr. Leslie Baumann, director of cosmetic dermatology at the University of Miami.
"This is not surprising," she said. "Patients quickly realize that these ineffective procedures are a waste of money."
The statistics on cosmetic procedures from the ASPS are based on a combination of data from its online national database of plastic surgery procedures and the results of an annual survey of about 21,000 board-certified dermatologists; ear, nose and throat specialists; and plastic surgeons. The responses are then aggregated and extrapolated to the entire population of physicians most likely to perform cosmetic and reconstructive plastic surgery procedures.
The 2008 statistics also highlight a trend toward greater use of cosmetic procedures by ethnic minorities. Cosmetic procedures increased slightly in all ethnic groups except in white patients, though white patients still accounted for the vast majority of cosmetic procedures performed last year.
The greatest level of increased interest was among Hispanic and black patients. The use of cosmetic procedures jumped 18% among Hispanic patients and 10% among blacks patients, compared with 2007. The most commonly requested procedures for ethnic minorities were Botox, injectable fillers, and chemical peels.
The increased use of cosmetic procedures by ethnic minorities is encouraging, said Dr. Eliot F. Battle Jr., a cosmetic dermatologist in Washington and an expert in treating ethnic skin. However, it raises serious concerns that some physicians are performing these procedures without the proper understanding of skin of color. Dr. Battle said that he is seeing more patients who come to him after experiencing side effects from laser treatments performed by other physicians.
He urged physicians to use care when treating patients with skin of color even if the laser used is marketed for all skin types. Without understanding the nuances of darker skin, patients can be harmed. "These patients cannot be treated as guinea pigs," he said.

Devices Limit Cellulite by Tightening of Skin
MAUI, HAWAII Laser and radiofrequency-based devices for the treatment of cellulite have gotten more efficient in the last half decade, according to Dr. David J. Goldberg.
Recent rapid advances in device therapy have led to improved regimens featuring fewer treatment sessions and better results, Dr. Goldberg said at the annual Hawaii dermatology seminar sponsored by Skin Disease Education Foundation.
Cellulite is not a diseaseit is the product of normal skin exposed to estrogenso there can be no "cure," said Dr. Goldberg, director of dermatologic laser research at Mount Sinai School of Medicine, New York. "Cellulite is really an annuity, not a disease. You never get rid of it. It always will come back." The improved skin appearance achieved with these devices results primarily from their skin-tightening effect.
The devices that work for cellulite are the same ones that achieve good results for facial skin tightening.
The devices work in the same general way, regardless of whether they utilize low-energy lasers, infrared, or unipolar, bipolar, or monopolar radiofrequency, he said. They achieve skin tightening by combining deep bulk heating with epidermal cooling to prevent blistering.
Dr. Goldberg explained how device therapy for cellulite has improved in the last 5 years.
▸ The early days. A prospective study in 35 women showed measurable improvement in buttock and thigh cellulite using the VelaSmooth (Synernon) device, which combines bipolar radiofrequency and infrared energy with suction (J. Cosmet. Laser Ther. 2004;6:187-90).
But bipolar radiofrequency does not penetrate nearly as deep as unipolar, so the skin-tightening effect was relatively modest, said Dr. Goldberg. "The problem is it took 12-14 treatments biweekly. That's pretty impractical for patients. And the results disappear pretty much as soon as you stop."
▸ Last year. Using the Accent unipolar diffuse radiofrequency device marketed by Alma Lasers, Dr. Goldberg treated 30 women with upper-thigh cellulite. Using 6 treatments spread over 12 weeks, he documented a mean 2.5-cm reduction in thigh circumference at 6 months follow-up. Twenty-seven of the 30 patients showed clinical improvement rated a mean 2.9 on a 1-4 scale. The benefit was achieved with no change in body weight (Dermatol. Surg. 2008;34:204-9).
The treatment sessions were brief and fairly painless, with no blistering, pigmentary changes, or scarring. Patients experienced no changes in blood lipid levels but had some diffuse erythema lasting 30-120 minutes
▸ Today. Dr. Goldberg was an investigator in a just-completed multisite study using a new 16-cm
"It's very time consuming. It takes a good, solid hour. And it's pretty uncomfortable. But you can still see improvement 6 months after a single treatment. So we've gone from 12-14 treatments with the original devices, to 6, to 1," he said.
He disclosed that he receives research grants from, and is on the speakers bureaus of, numerous medical device and pharmaceutical companies. SDEF and this newspaper are owned by Elsevier.

New Evidence Indicates Laser-Assisted Lipolysis Results in Skin Tightening
MIAMI BEACH Sure, it's nice to tell patients that laser-assisted lipolysis will tighten their skin, but now there is evidence to prove it.
Dr. Bruce E. Katz and his colleagues demonstrated the tightening effects of laser-assisted lipolysis by tattooing a 4-by 4-cm square on the abdomen, arms, hips, or thighs of 30 patients.
At 3 months' follow-up, a mean 18% reduction was observed in an ongoing, multicenter study, accroding to Dr. Katz.
"This is the first evidence of skin tightening," he said at the South Beach Symposium. "And we've seen similar findings out to 6 months."
The investigators also performed punch biopsies to examine the histology at treated sites. Results showed new fibrosis, adipocytes, histiocytes, and markers of fat-cell lysis, said Dr. Katz of the department of dermatology at Mount Sinai School of Medicine, New York.
Patients were treated using the Smartlipo system (Cynosure Inc.), which features a hollow, 1- to 2-mm cannula inserted through a small incision to deliver Nd:YAG laser energy. After the laser liquefies fat cells, they are drained away through the same cannula.
This device combines a 1,064-nm wavelength for a gradual thermal effect and to mediate coagulation of blood vessels, as well as a 1,320-nm wavelength to promote energy absorption by fat and water. For this study, Dr. Katz set the system to deliver 20 W of the 1,064-nm energy and 12 W of the 1,320-nm wavelength.
The tightening results are supported by another study in process by Dr. Barry E. DiBernardo, a plastic surgeon in private practice in Montclair, N.J. Dr. DiBernardo compared laser-assisted lipolysis with liposuction in a split-treatment study of 10 women.
Dr. DiBernardo tattooed a 5- by 5-cm square on areas to be treated and found 37% greater skin tightening with laser-assisted lipolysis versus liposuction alone at 1 month. "At 3 months, he found 54% greater tightening with laser lipolysis," Dr. Katz said.
In addition to a stand-alone treatment for skin tightening, the system could be a nice alternative for patients who are candidates for face and neck tightening surgery, Dr. Katz said. Laser lipolysis is indicated for all areas with localized adipocyte deposits, as well as places where liposuction is indicated but the treatment could worsen skin laxity.
With any technology it is important to ask: "Do the risks outweigh the benefits?" Dr. Katz said. "We saw this in ultrasonic liposuction years ago."
To find out, he and a colleague assessed the incidence of adverse events and touch-up treatments required by 537 patients treated over 18 months at a single center (J. Cosmet. Laser Ther. 2008;10:2313). They found a 1% complication rate, including one local infection and three minor burns, all of which resolved, Dr. Katz said at the meeting.
There were 19 touch-up procedures for a 3.4% rate, versus the 10%-12% reported in the liposuction literature. "The most important finding was there were no serious side effects at all," he said.
Dr. Katz disclosed that he is a Cynosure stockholder.

MIAMI BEACH Sure, it's nice to tell patients that laser-assisted lipolysis will tighten their skin, but now there is evidence to prove it.
Dr. Bruce E. Katz and his colleagues demonstrated the tightening effects of laser-assisted lipolysis by tattooing a 4-by 4-cm square on the abdomen, arms, hips, or thighs of 30 patients.
At 3 months' follow-up, a mean 18% reduction was observed in an ongoing, multicenter study, accroding to Dr. Katz.
"This is the first evidence of skin tightening," he said at the South Beach Symposium. "And we've seen similar findings out to 6 months."
The investigators also performed punch biopsies to examine the histology at treated sites. Results showed new fibrosis, adipocytes, histiocytes, and markers of fat-cell lysis, said Dr. Katz of the department of dermatology at Mount Sinai School of Medicine, New York.
Patients were treated using the Smartlipo system (Cynosure Inc.), which features a hollow, 1- to 2-mm cannula inserted through a small incision to deliver Nd:YAG laser energy. After the laser liquefies fat cells, they are drained away through the same cannula.
