Optimizing Redness Reduction, Part 2: Rosacea and Cosmeceuticals
Medical Spa Inhouse Marketing Lures 6,000 New Patients a Year
SANTA MONICA, CALIF. Don't bother leafing through the pages of glossy, upscale San Diego magazines to find advertisements for Dr. Mitchel P. Goldman's successful, 6-year-old medical spa.
Magazine marketing recruits mostly "looky-loos," said Dr. Goldman at a cosmetic dermatology seminar sponsored by Skin Disease Education Foundation.
Most of the marketing for La Jolla (Calif.) Spa MD occurs only after a patient enters the column-framed, wood-and-glass doors and is greeted by one of 92 staff members for a dermatology, cosmetic surgery, or cosmetic dentistry procedure; wellness/longevity consultation; spa service, or a trip to the retail center.
Then, "it's all marketing," from the videos playing in the waiting room and the artfully displayed brochures to the up-close (and sometimes alarming) computer analysis of patients' faces and flaws, with a scorecard and list of recommended procedures.
The patient who arrives for a simple $150 massagethe least profitable service in the spamight also be informed that a cancellation has left a Botox appointment available, for 10% off.
Spa aestheticians, massage therapists, and make-up specialists receive incentives when their clients sign up for cosmetic medical procedures.
Established patients, whose names go into the computer database, receive discount coupons, specials, and gift cards. Birthday and anniversary cards arrive each year, with $50-off coupons. The spa newsletter features special promotions.
Upward of 10,000 Web site visitors a month, often drawn to the site by word-of-mouth, learn about spa and medical services, schedule spa "packages"(the 3-hour, four-treatment "anti-cellulite sampler" goes for $620), and purchase products once they establish an online account, thus entering the database to receive e-mail blast offers for discount services.
Although he is not big on print and broadcast advertising, Dr. Goldman said he is generous with his time for interviews with journalists. He also promotes the spa by making generous charitable donations. At any given time, the practice may be conducting 20 active clinical trials, any of which may draw a newcomer who will then return as a paying customer.
Dr. Goldman's unconventional, upscale marketing efforts seem to be paying off. In the past 3 years, the number of new patients rose from 5,600 to 5,700, to 6,000, respectively, he said.

What's Hot and What's Not at An Upscale California MediSpa
Dr. Goldman, founder of the La Jolla Spa MD medical spa, recently shared his observations about which treatments are "in," which are "out," and which aren't worth the trouble.
Ubiquitous Botox procedures, always a draw, and requests for other facial fillers have been up 25% in recent months at his spa, as a down economy induces penny-pinching socialites to seek out temporary, relatively affordable alternatives to big-ticket cosmetic surgery procedures, according to Dr. Goldman.
As a whole, aesthetic surgery procedures declined 10% last year, while appointments for plastic surgery took a 50% dive, said Dr. Goldman. Adding that breast implants, facelifts, and blepharoplasty procedures have seen a decline "all over California."
He predicted the popularity of these procedures will rebound with "pent-up demand" once the economy improves.
Leg vein procedures, hair removal, photodynamic therapy for acne, and intense pulsed light treatments are all holding their own, and cosmetic dentistry has proved to be "very profitable," he said.
The spa's retail center, which features a variety of skin products, has shown 133% growth in 5 years, now generating $1.5 million/year in sales.
Dr. Goldman doesn't recommend catering to patients requesting laser tattoo removal.
"They're the worst patients in the world," who may have paid $100 while drunk to get a tattoo and are irritated at the notion of paying thousands for 5-50 treatments to have them removed, he said.

States Eye 'Luxury' Aesthetic Procedure Taxes, Restrictions
SANTA MONICA, CALIF. When state coffers get low, legislators go hunting for cash.
Lately, in states such as Maryland and New York, lawmakers have been considering taxes on "luxury" items from upscale cars to aesthetic surgery offices, Dr. Ron Wheeland said at a cosmetic dermatology seminar sponsored by Skin Disease Education Foundation.
"This is not a new idea," he said, citing longstanding sales taxes on cosmetic surgery procedures in New Jersey and Minnesota.
In New Jersey, in fact, a Senate bill seeks to repeal the 2004 sales tax on cosmetic procedures because it generated far less money than expected.
But that experience hasn't stopped other states from trying.
In Tennessee, it's the same tune with different lyrics, as legislators consider a tax on devices and equipment used in cosmetic procedures, rather than targeting the consumers who pay for laser procedures and facelifts, he said.
Aesthetic procedures are also in the legislative spotlight with regard to safety and oversight, Dr. Wheeland said during a talk on the "new truths" in dermatology.
Restricting procedures and imposing tighter oversight measures are seen as "white hat" moves for legislators, who like to be seen protecting constituents, even in cases when not all the facts are in, said Dr. Wheeland, director of dermatologic surgery at the University of Missouri-Columbia.
In Virginia, House Bill 1399 would establish as a professional entity "laser light technicians" who would report not to the state boards that oversee physicians or nurses but to the board that oversees barbers and cosmetologists.
"I can only hope that that bill is defeated," he said.
In Georgia, Illinois, and California, proposed legislation would require preoperative examinations prior to laser or cosmetic surgical procedures. In Arizona, a bill is being considered that would allow nonphysicians to perform aesthetic procedures with lasers or light devices without physician supervision if they pass a 40-hour course.
Another bill in Illinois, which was referred to the rules committee in April, would permit only board-certified plastic surgeons to inject Botox, perform chemical peels, or perform aesthetic laser procedures.
"This one bothers me the most," said Dr. Wheeland. "When you think of these three procedures in particular, the first thing that ought to pop into your mind is that all three were developed by dermatologists."
It behooves dermatologists to be alert to themes and patterns in legislative proposals and to become involved when their own states are considering laws that would have a direct impact on the practice of dermatology, Dr. Wheeland said.

Severe Sagging of Facial Skin Associated With Two Genes
KYOTO, JAPAN Facial sagging has been found to be a function not only of aging, gravity, and environmental and lifestyle factors, but also of genetics.
Melanocortin 1 receptor (MC1R) and elastin proved to be significantly associated with the sagging of facial skin in a genetic study of 530 white women age 44-70 years, Christiane Guinot, Ph.D., said at an international investigative dermatology meeting.
The MC1R gene plays a major role in skin pigmentation and sensitivity to sunlight. Elastin figures prominently in arterial wall elasticity. Neither gene had previously been linked to sagging of facial skin, said Dr. Guinot of the Chanel Epidermal and Sensory Research and Investigation Center and the University of Tours (France).
Dr. Guinot, who is president of the French Statistical Association, reported that 121 of the 530 women had severe sagging of the facial skin based upon a structured 0-10 rating scale. Nongenetic factors that proved significantly associated with severe facial sagging were age, being overweight or obese, and being menopausal and not on hormone replacement therapy (HRT).
An analysis that adjusted for these factors revealed that women carrying two variants of the MC1R gene were at a 2.3-fold increased risk of severe sagging, compared with those with the wt/wt (wild type) genotype. Women with the Ser422Gly polymorphism of the elastin gene were at a 1.8-fold increased risk.
Overweight women were 1.7 times more likely to have severe facial sagging than normal-weight women; obese women were at 2.3-fold increased risk. Menopausal women not on HRT were an adjusted 2.1-fold more likely to have severe facial skin sagging than those on HRT.
Neither smoking status nor skin color was significantly associated with severity of facial skin sagging, although the spectrum of skin colors in this all-Caucasian study was limited, Dr. Guinot noted at the meeting of the European Society for Dermatological Research, the Japanese Society for Investigative Dermatology, and the Society for Investigative Dermatology. The study was sponsored by Chanel.

Angelica: Part I
Angelica sinensis, better known as dong quai, is a fragrant perennial plant that has been used for medicinal purposes for more than a thousand years in China, Japan, and Korea. A. sinensis is best known as a traditional treatment for dysmenorrhea, amenorrhea, menopause, and related conditions in women.
The dried root of A. sinensis is included in several herbal formulations, typically for amenorrhea, endometriosis and premenstrual syndrome, and as a hormone replacement therapy alternative, even though Western medicine has not established whether such indications are appropriate or justified (Integrative Cancer Therapies 2003;2:120-38; Nurse Pract. 1997;22:55-6, 61-6).
Despite numerous anecdotal reports of its effectiveness in exerting estrogenic effects, a study of 71 postmenopausal women showed that A. sinensis alone failed to produce estrogenic effects on endometrial thickness or vaginal maturation. In addition, the herb eased menopause symptoms no better than placebo (Fertil. Steril. 1997;68:981-6).
Although the reported effects of this reputed “women's herb” remain dubious in the West, evidence is increasing that A. sinensis possesses anticarcinogenic properties, which are often associated with antioxidant potential and implications for dermatologic use.
In this vein, the potent antioxidant ferulic acid, which was featured in this column in October 2005, has been identified as a major active component of A. sinensis, along with ligustilide (J. Pharm. Biomed. Anal. 2005;38:664-9).
Antitumor Action
Investigators assessing the antitumor effects, in vitro and in vivo, of a chloroform extract of A. sinensis on glioblastoma multiforme brain tumors reported that the herb strongly inhibits the growth of malignant brain tumor cells, via cell cycle arrest and apoptosis induction, without damaging fibroblasts.
In vitro, angelica spurred p53-dependent and -independent pathways, resulting in apoptosis. In human DBTRG-05MG and rat RG2 glioblastoma multiforme tumor cells, angelica suppressed malignant growth and reduced tumor volume. Researchers concluded that A. sinensis merits more research and consideration as a potential brain tumor therapeutic agent (Clin. Cancer Res. 2005;11:3475-84).
In a study that assessed the antioxidant activities of three herbs used frequently in traditional Chinese medicine—A. sinensis, Lycium barbarum, and Poria cocos—aqueous extracts of these herbs concentration-dependently displayed antioxidant activities. L. barbarum extract was the strongest, but all the extracts inhibited ferric chloride-ascorbic acid-induced lipid peroxidation in rat liver homogenate in vitro, and demonstrated significant superoxide anion-scavenging activity as well as antisuperoxide formation activity (Phytother. Res. 2004;18:1008-12).
Another study revealed that the total polysaccharide from A. sinensis confers antitumor effects on in vivo murine models and, in vitro, inhibits invasion and metastasis of hepatocellular cancer cells (World J. Gastroenterol. 2003;9:1963-7).
In a study of the effects of 14 commonly used herbs on cellular proliferation and apoptosis of a hepatic stellate cell line in rats, A. sinensis was among five herbs that exhibited both antiproliferative and proapoptotic properties in association with upregulation of Fas and Bax and downregulation of Bcl-xL. Investigators suggested that further research is warranted into the antifibrotic potential of these herbs to promote apoptosis in hepatic stellate cells, which are integral in hepatic fibrosis and are known to possess antifibrotic activity (J. Ethnopharmacol. 2005;100:180-6).
Action in the Skin
Perhaps the evidence providing the most direct link to dermatologic application comes from a study of the effects of A. sinensis on melanocytes and tyrosinase activity. The potent herb was noted for significantly promoting melanocytic proliferation, which substantially increased cell counts, and fostering melanin synthesis and melanocytic tyrosinase activity. Such actions, the investigators concluded, suggest a mechanism that may justify the use of this fragrant botanical in the treatment of skin dyschromias (Di Yi Jun Yi Da Xue Xue Bao 2003;23:239-41).
In addition, A. sinensis is an ingredient in Si-Wu-Tang, a traditional Chinese formula used to treat pruritus, chronic skin inflammation, and other conditions (Biol. Pharm. Bull. 2002;25:1175-8).
Gastrointestinal Protection
Polysaccharides isolated from the root of A. sinensis have been found to impart an ulcer-protective effect.
Specifically, angelica extract dose-dependently inhibited various neutrophil-dependent gastrointestinal lesions induced in rats by orally administered ethanol or indomethacin. The investigators concluded that angelica exhibits anti-inflammatory action, and might be effective in preventing neutrophil-dependent gastrointestinal damage (Planta Med. 2000;66:348-51).
Some of the same researchers followed up by demonstrating that A. sinensis extract has a direct wound-healing effect on gastric epithelial cells. The herb significantly promoted epithelial cell migration over an artificial wound, and dose-dependently stimulated DNA synthesis as well as concurrent epithelial growth factor mRNA expression (Life Sci. 2001;68:961-8).
Subsequent research confirmed that A. sinensis crude extract does dose-dependently confer a direct healing effect on gastric mucosal lesions in rats, and it also promotes wound repair in culture (Biochem. Pharmacol. 2001;61:1439-48).
Other Actions
An evaluation of the therapeutic activity of A. sinensis on focal ischemic injury in rats showed reduced volume of cerebral infarction, reduced Bax protein expression, and significant decreases in the number of neuronal apoptosis cells (Clin. Hemorheol. Microcirc. 2005;32:209-15). Improvement in microcirculation, with obvious implications for various organs, was achieved by the intravenous injection of A. sinensis in a study examining the mechanism of microcirculation disorder in the tongue in the common oral disease glossodynia (Hua Xi Kou Qiang Yi Xue Za Zhi 2000;18:101-2, 108).
Aqueous extract of A. sinensis has been shown in a rabbit model to impart myocardial protective effects caused by ischemia reperfusion (Zhongguo Zhong Xi Yi Jie He Za Zhi 1995;15:486-8).
A study of the effects of two herbs used in traditional Chinese medicine to treat bleomycin-induced pulmonary fibrosis in rats revealed that ligustrazini and, to a lesser extent, A. sinensis, lessened the severity of alveolitis symptomatic of pulmonary fibrosis (Zhonghua Jie He He Hu Xi Za Zhi 1996;19:26-8).
Similarly, a traditional Chinese medicinal decoction containing A. sinensis and Astragalus membranaceus, which is used for stimulating production of red blood cells and bolstering cardiovascular function, was shown in a rat model to confer myocardial protection against ischemia-reperfusion injury (Phytother. Res. 2000;14:195-9).
Injection of Qi-Xue, another Chinese herb combination containing A. sinensis, Panax ginseng, and Astragalus monogholicus, is thought to prevent severe hypoxic pulmonary hypertension by enhancing heart function (Zhongguo Yi Xue Ke Xue Yuan Xue Bao 1990;12:51-5).
In high doses, A. sinensis may increase susceptibility to photosensitivity reactions, so sun exposure should be curtailed. It also is contraindicated for patients taking warfarin (Lancet 2000; 355:134-8; J. Am. Med. Womens Assoc. 1999;54:191-2, 195).
Conclusions
A. sinensis is one of the oldest and most popular herbs used in traditional Chinese medicine. While there is an expanding body of research on the broad medical applications of this botanical product, and it is being used in multibotanical formulations, there is minimal evidence as yet to warrant its use for dermatologic purposes.
Recent studies, however, do seem to indicate that A. sinensis has antioxidant and antitumorigenic activity and that it warrants further investigation, including for its potential benefit to the skin. Research associating angelica with melanocytic, anti-inflammatory, and antipruritic properties also deserves attention and further study.
Although little dermatologic research has been done, the Angelica sinensis plant, also known as dong quai, appears to have antioxidant and antitumorigenic activity.

The dried root of A. sinensis is included in several herbal formulations, typically for amenorrhea, endometriosis and premenstrual syndrome, and as a hormone replacement therapy alternative, even though Western medicine has not established whether such indications are appropriate or justified (Integrative Cancer Therapies 2003;2:120-38; Nurse Pract. 1997;22:55-6, 61-6).
Despite numerous anecdotal reports of its effectiveness in exerting estrogenic effects, a study of 71 postmenopausal women showed that A. sinensis alone failed to produce estrogenic effects on endometrial thickness or vaginal maturation. In addition, the herb eased menopause symptoms no better than placebo (Fertil. Steril. 1997;68:981-6).
Although the reported effects of this reputed “women's herb” remain dubious in the West, evidence is increasing that A. sinensis possesses anticarcinogenic properties, which are often associated with antioxidant potential and implications for dermatologic use.
In this vein, the potent antioxidant ferulic acid, which was featured in this column in October 2005, has been identified as a major active component of A. sinensis, along with ligustilide (J. Pharm. Biomed. Anal. 2005;38:664-9).
Antitumor Action
Investigators assessing the antitumor effects, in vitro and in vivo, of a chloroform extract of A. sinensis on glioblastoma multiforme brain tumors reported that the herb strongly inhibits the growth of malignant brain tumor cells, via cell cycle arrest and apoptosis induction, without damaging fibroblasts.
In vitro, angelica spurred p53-dependent and -independent pathways, resulting in apoptosis. In human DBTRG-05MG and rat RG2 glioblastoma multiforme tumor cells, angelica suppressed malignant growth and reduced tumor volume. Researchers concluded that A. sinensis merits more research and consideration as a potential brain tumor therapeutic agent (Clin. Cancer Res. 2005;11:3475-84).
In a study that assessed the antioxidant activities of three herbs used frequently in traditional Chinese medicine—A. sinensis, Lycium barbarum, and Poria cocos—aqueous extracts of these herbs concentration-dependently displayed antioxidant activities. L. barbarum extract was the strongest, but all the extracts inhibited ferric chloride-ascorbic acid-induced lipid peroxidation in rat liver homogenate in vitro, and demonstrated significant superoxide anion-scavenging activity as well as antisuperoxide formation activity (Phytother. Res. 2004;18:1008-12).
Another study revealed that the total polysaccharide from A. sinensis confers antitumor effects on in vivo murine models and, in vitro, inhibits invasion and metastasis of hepatocellular cancer cells (World J. Gastroenterol. 2003;9:1963-7).
In a study of the effects of 14 commonly used herbs on cellular proliferation and apoptosis of a hepatic stellate cell line in rats, A. sinensis was among five herbs that exhibited both antiproliferative and proapoptotic properties in association with upregulation of Fas and Bax and downregulation of Bcl-xL. Investigators suggested that further research is warranted into the antifibrotic potential of these herbs to promote apoptosis in hepatic stellate cells, which are integral in hepatic fibrosis and are known to possess antifibrotic activity (J. Ethnopharmacol. 2005;100:180-6).
Action in the Skin
Perhaps the evidence providing the most direct link to dermatologic application comes from a study of the effects of A. sinensis on melanocytes and tyrosinase activity. The potent herb was noted for significantly promoting melanocytic proliferation, which substantially increased cell counts, and fostering melanin synthesis and melanocytic tyrosinase activity. Such actions, the investigators concluded, suggest a mechanism that may justify the use of this fragrant botanical in the treatment of skin dyschromias (Di Yi Jun Yi Da Xue Xue Bao 2003;23:239-41).
In addition, A. sinensis is an ingredient in Si-Wu-Tang, a traditional Chinese formula used to treat pruritus, chronic skin inflammation, and other conditions (Biol. Pharm. Bull. 2002;25:1175-8).
Gastrointestinal Protection
Polysaccharides isolated from the root of A. sinensis have been found to impart an ulcer-protective effect.
Specifically, angelica extract dose-dependently inhibited various neutrophil-dependent gastrointestinal lesions induced in rats by orally administered ethanol or indomethacin. The investigators concluded that angelica exhibits anti-inflammatory action, and might be effective in preventing neutrophil-dependent gastrointestinal damage (Planta Med. 2000;66:348-51).
Some of the same researchers followed up by demonstrating that A. sinensis extract has a direct wound-healing effect on gastric epithelial cells. The herb significantly promoted epithelial cell migration over an artificial wound, and dose-dependently stimulated DNA synthesis as well as concurrent epithelial growth factor mRNA expression (Life Sci. 2001;68:961-8).
Subsequent research confirmed that A. sinensis crude extract does dose-dependently confer a direct healing effect on gastric mucosal lesions in rats, and it also promotes wound repair in culture (Biochem. Pharmacol. 2001;61:1439-48).
Other Actions
An evaluation of the therapeutic activity of A. sinensis on focal ischemic injury in rats showed reduced volume of cerebral infarction, reduced Bax protein expression, and significant decreases in the number of neuronal apoptosis cells (Clin. Hemorheol. Microcirc. 2005;32:209-15). Improvement in microcirculation, with obvious implications for various organs, was achieved by the intravenous injection of A. sinensis in a study examining the mechanism of microcirculation disorder in the tongue in the common oral disease glossodynia (Hua Xi Kou Qiang Yi Xue Za Zhi 2000;18:101-2, 108).
Aqueous extract of A. sinensis has been shown in a rabbit model to impart myocardial protective effects caused by ischemia reperfusion (Zhongguo Zhong Xi Yi Jie He Za Zhi 1995;15:486-8).
A study of the effects of two herbs used in traditional Chinese medicine to treat bleomycin-induced pulmonary fibrosis in rats revealed that ligustrazini and, to a lesser extent, A. sinensis, lessened the severity of alveolitis symptomatic of pulmonary fibrosis (Zhonghua Jie He He Hu Xi Za Zhi 1996;19:26-8).
Similarly, a traditional Chinese medicinal decoction containing A. sinensis and Astragalus membranaceus, which is used for stimulating production of red blood cells and bolstering cardiovascular function, was shown in a rat model to confer myocardial protection against ischemia-reperfusion injury (Phytother. Res. 2000;14:195-9).
Injection of Qi-Xue, another Chinese herb combination containing A. sinensis, Panax ginseng, and Astragalus monogholicus, is thought to prevent severe hypoxic pulmonary hypertension by enhancing heart function (Zhongguo Yi Xue Ke Xue Yuan Xue Bao 1990;12:51-5).
In high doses, A. sinensis may increase susceptibility to photosensitivity reactions, so sun exposure should be curtailed. It also is contraindicated for patients taking warfarin (Lancet 2000; 355:134-8; J. Am. Med. Womens Assoc. 1999;54:191-2, 195).
Conclusions
A. sinensis is one of the oldest and most popular herbs used in traditional Chinese medicine. While there is an expanding body of research on the broad medical applications of this botanical product, and it is being used in multibotanical formulations, there is minimal evidence as yet to warrant its use for dermatologic purposes.
Recent studies, however, do seem to indicate that A. sinensis has antioxidant and antitumorigenic activity and that it warrants further investigation, including for its potential benefit to the skin. Research associating angelica with melanocytic, anti-inflammatory, and antipruritic properties also deserves attention and further study.
Although little dermatologic research has been done, the Angelica sinensis plant, also known as dong quai, appears to have antioxidant and antitumorigenic activity.

Fractional Technology Brings New Life to CO2 Laser
SANTA MONICA, CALIF. In the world of cosmetic skin rejuvenation, what's old is new again.
Ablative laser resurfacing with CO2 lasersusing fractionalized laser energy this time around to reduce healing timedominated a recent cosmetic dermatology seminar sponsored by Skin Disease Educational Foundation.
"It's almost like we're rediscovering the wheel," said Dr. Mitchel Goldman, who is a dermatologist in private practice in La Jolla, Calif.
Dr. Goldman explained that he has 32 lasers in his office, but the only ones that truly smooth wrinkles and tighten the skin are the CO2 and erbium:YAG lasers.
The others, he said, mainly address pigmentation issues and vascular changes. They demand multiple visits, multiple passes, and generate multiple complaints from patients who see little improvement in their overall appearance.
The drawback with CO2 lasers is the downtime to allow for healing, even with fractional ablative resurfacing. "No matter what anyone says, there is some downtime," now averaging approximately 4-5 days, compared with the 1-4 weeks for first-generation CO2 lasers, he said.
The lure of fractional CO2 resurfacing is its reliability in producing meaningful cosmetic skin changes with less damage by creating pinpoint "drill holes" linked by tissue bridges.
Among 356 patients who have undergone fractionalized CO2 laser procedures in his practice in the past 3 years, "we have seen virtually no complications," he said. A 1% incidence of herpes was eliminated by the addition of antiviral prophylaxis in every case. There has been a 2% rate of erythema lasting for more than 4 days.
"That was it," he said, detailing his experience with Lumenis systems.
The three big players in ablative fractional resurfacing, according to Dr. Goldman, are the Fraxel Re:pair by Reliant, and the ActiveFX and DeepFX by Lumenis.
Speakers discussed their experiences with each, coming to the conclusion that the devices induce significant nonspecific thermal damage that induces collagen remodeling, yet invite far fewer complications than traditional CO2 lasers, including burns and pigmentation abnormalities.
"I think there's been a quantum shift back toward CO2. The reason is, CO2 works," said Dr. John Fezza of Sarasota, Fla.
"There's no question, there is some redness," acknowledged Dr. Fezza, who performed a real-time video laser resurfacing procedure on a 42-year-old woman with sun damage during the meeting.
Still, in more than 2 years, he has seen no lasting hyper- or hypopigmentationcommon side effects associated with traditional CO2 laser resurfacing.
Patients with realistic expectations know that if they have a fractionated CO2 laser procedure on a Friday, they'll be ready to go out with makeup by Monday.
"They don't mind house arrest for 3 days," he said.
Dr. Goldman said he considers fractionated CO2 lasers "safe if you go within the [recommended] parameters," but they require care and caution just like their prototypes.
Dr. Christopher Zachary, professor and chair of dermatology at the University of California, Irvine, said he believes the reason fractionated CO2 lasers have a measurable impact on wrinkling and skin tightening is that "they have the ability to induce a defect that is deeper than it is wide."
Dr. David Goldberg agreed. For photo damage and superficial rhytids, the key is density, but depth is what matters if the goal is skin tightening, he said.
"I'm pretty convinced," Dr. Goldberg said.
All speakers at the session disclosed grant support, laser equipment loans, and/or speakers bureau ties to companies that manufacture lasers, including Reliant and Lumenis.

Versajet Reduces Blood Loss During Burn Excision
CHICAGO Use of the Versajet Hydrosurgery system was associated with less blood loss and a larger area of excision than was the Goulian-Weck knife in a retrospective study of 50 patients with burn wounds.
The average estimated blood loss was 174 mL for patients who had their wounds excised with the Versajet system, compared with 659 mL for wounds excised with a Goulian-Weck knife. The difference was significant, Dr. Laura S. Johnson said at the annual meeting of the American Burn Association.
The study's primary end point of blood loss in milliliters as a function of area excised in centimeters squared was significantly lower in the Versajet group than in the Goulian-Weck knife group (mean 0.28 cc/cm
The findings suggest that the Versajet system could allow for earlier excision of burn wounds, perhaps as early as the resuscitation period, Dr. Johnson and her colleagues at the burn center of the Washington (D.C.) Hospital Center concluded.
Dr. James Jeng, associate director of the burn center, said in an interview that they've used the Versajet system since it gained U.S. approval for wound debridement roughly 2 years ago, and that its biggest benefit lies in its ability to discriminate between live and dead tissue.
"This knife is not dumb; it just doesn't cut where you put it, but discriminates between live and dead tissue based on tensile strength," he said. "Necrotic tissue has lower tensile strength, so we can dial down the strength [of the water jet] to partition live from dead tissue. It's pretty much replaced the cold knife for me. This is a poor man's laser ablation."
The Versajet system uses a pressure pump to force a stream of sterile saline through a small jet nozzle at the end of a handpiece, producing both a high-velocity stream and a local vacuum on the surface of the debridement area. The stream is directed backward across the operating window and into an evacuation collector tube in the handpiece, which also collects any debris or contaminants.
The review included 50 patients (mean age 40 years) with full- and split-thickness burns ranging in percentage of total body surface area from 5% to more than 50%. Excisions were performed as early as day 1, and were carried out over a 6-month period by Dr. Jeng.
Researchers calculated the estimated blood loss (EBL) by using blood-soaked laparotomy tapes for patients undergoing Goulian-Weck knife excision and by measuring the fluid in the evacuation tube and subtracting the amount of saline used during excision.
Dr. Johnson, a surgical resident, noted that the EBL for the Goulian-Weck knife group was higher than in published reports. However, the EBL for the Versajet group was significantly lower than traditional literature results for early excision, suggesting that the Versajet system does have benefit during this period, she said.
Dr. Jeng said that pre- and postoperative hematocrit levels don't take into account intraoperative fluid administration and equilibration issues, and that his group is looking into intraoperative optical recording and colorimetric cineanalysis for future studies.
The investigators received no funding for the study, and disclosed no relevant conflicts of interest.

The findings suggest that the Versajet system could allow for earlier excision of burn wounds, perhaps as early as the resuscitation period, Dr. Johnson and her colleagues at the burn center of the Washington (D.C.) Hospital Center concluded.
Dr. James Jeng, associate director of the burn center, said in an interview that they've used the Versajet system since it gained U.S. approval for wound debridement roughly 2 years ago, and that its biggest benefit lies in its ability to discriminate between live and dead tissue.
"This knife is not dumb; it just doesn't cut where you put it, but discriminates between live and dead tissue based on tensile strength," he said. "Necrotic tissue has lower tensile strength, so we can dial down the strength [of the water jet] to partition live from dead tissue. It's pretty much replaced the cold knife for me. This is a poor man's laser ablation."
The Versajet system uses a pressure pump to force a stream of sterile saline through a small jet nozzle at the end of a handpiece, producing both a high-velocity stream and a local vacuum on the surface of the debridement area. The stream is directed backward across the operating window and into an evacuation collector tube in the handpiece, which also collects any debris or contaminants.
The review included 50 patients (mean age 40 years) with full- and split-thickness burns ranging in percentage of total body surface area from 5% to more than 50%. Excisions were performed as early as day 1, and were carried out over a 6-month period by Dr. Jeng.
Researchers calculated the estimated blood loss (EBL) by using blood-soaked laparotomy tapes for patients undergoing Goulian-Weck knife excision and by measuring the fluid in the evacuation tube and subtracting the amount of saline used during excision.
Dr. Johnson, a surgical resident, noted that the EBL for the Goulian-Weck knife group was higher than in published reports. However, the EBL for the Versajet group was significantly lower than traditional literature results for early excision, suggesting that the Versajet system does have benefit during this period, she said.
Dr. Jeng said that pre- and postoperative hematocrit levels don't take into account intraoperative fluid administration and equilibration issues, and that his group is looking into intraoperative optical recording and colorimetric cineanalysis for future studies.
The investigators received no funding for the study, and disclosed no relevant conflicts of interest.
