A 755nm alexandrite picosecond second laser with a fractionated handpiece can improve pigmentation and skin texture on the décolleté, but wrinkle reduction is short-term, according to a study published in Lasers in Surgery and Medicine (February 2016) by Douglas C. Wu MD, PhD, et al. Twenty subjects with Fitzpatrick skin types I-IV received a series of four laser treatments at three- week intervals. Follow-up evaluation was performed one and three months post-treatment by a masked investigator who assessed dyspigmentation, erythema, keratosis, texture and rhytides on a standardized fi ve- point scale, a Global Aesthetic Improvement Scale, and investigator and subject satisfaction questionnaires. Evaluations revealed a statistically signifi cant improve- ment in dyspigmentation, keratosis and skin texture at both one-month and three-month follow-up. There was an initial visible improvement in rhytides at one month, but the improvement was not maintained at three months. The majority of subjects (14) were satisfi ed with the treatment, with one being extremely satisfi ed and six being extremely dissatisfi ed. PICOSECOND ALEXANDRITE LASER FOR DÉCOLLETAGE PHOTODAMAGE HA Fillers Provide Long- Term Collagen Stimulation Patients who undergo cellulite treatment with the Cellfi na (Merz Aesthetics) subcision and vacuum device are maintaining results even three years after treatment, according to new data presented at the annual meeting of the American Academy of Dermatology (A AD) in March. Michael Kaminer, MD, of SkinCare Physicians in Chestnut Hill, Massachusetts, shared follow-up data from his multicenter pivotal study published last year in Dermatologic Surgery. In the original study, 96% of patients were satisfi ed or very satisfi ed with their results at two years postprocedure. The average improve- ment was 2.0 points on a 0-5 Cellulite Severity Scale at both one- and two-year follow-up. Three-year follow-up data of the 45 remaining patients (out of 55 in the original study) showed "essentially the same" sustained improve- ment, said Dr. Kaminer. The average results were nearly equal to the 2.1-point reduction seen at three months and visible improvement on the Global Aesthetic Improvement Scale was actually better at three years than at three months (100% vs. 98%). "This is not subtle," said Dr. Kaminer. "It's a very, very noticeable improvement that is identifi - able to a blinded physician." Patient satisfaction scores also remained high at three years post- procedure with 23 of the 45 patients (51%) satisfi ed, and 19 (42%) very satisfi ed. Cellfi na Effective at Three Years A study published in Dermatologic Surgery (March 2016) from researchers Fabiana Braga MD, MSc, et al, revealed that treatment with hyaluronic acid (HA) fi llers creates not only short-term fi lling of lines and wrinkles but also dermal remod- eling that provides sustained clinical results. Twenty patients were enrolled and 16 women (ages 40 to 50) completed the study. Each received HA fi ller injections in the nasolabial folds and preauricular regions of the face. Skin biopsies of the preauricular regions were performed prior to treatment and at three and nine months after the procedure. The patients who completed the study had demonstrated improvement 12 months after treatment. Morphologic evaluation showed increases in the epidermal layers and a statistically signifi cant increase in collagen fi bers at three and nine months after the procedure (34.2% ± 31.5% and 39.5% ± 39.7%, respectively). 8 MAY/JUNE 2016 | Med Esthetics TOP RIGHT: © GETTY IMAGES; BOTTOM: PHOTOS COURTESY OF MERZ AESTHETICS BEST PR ACTICES
