BEST PR ACTICES © GETTY IMAGES; BOTTOM: COURTESY OF REVITALASH Picosecond Nd:YAG For Multicolor Tattoos The Syneron-Candela PicoWay laser can achieve more than 79% clearance on multicolor tattoos, according to a new prospective study published in Lasers in Surgery and Medicine (September 2015). Eric Bernstein, MD, et al, used a prototype of the picosecond-domain, frequency- doubled Nd:YAG laser system to treat 31 tattoos in 21 subjects. Treatment parameters for each subject were based on their Fitzpatrick skin type; the color and intensity of tattoo ink; the clinical whitening response; and the photoacoustic effect of laser pulses upon various portions of the tattoo. The researchers treated black, blue, green and purple inks with the 1064nm wavelength, while red and yellow inks were treated with the 532nm wavelength. Treatments were administered with beam diameters ranging from 3mm to 5mm, and fl uences that ranged from 1.4J/cm 2 to 5.3J/cm 2 (1064nm) and from 0.4J/cm 2 to 2.1J/cm 2 (532nm). The average clearance overall as rated by blinded observers evaluating randomized digital photographs was 79% ± 0.9% after an average of 6.5 treatments. Of the 31 tattoos completing treatment, six had evidence of mild hyper- or hypopigmentation. The removal of greater than 100ml of fat per unit of body mass index during liposuction leads to an increased risk of complications, according to researchers Ian Chow, et al, of the Northwest University Feinberg School of Medicine. For their retrospective study, they reviewed 4,534 lipectomy cases through the Tracking Operations and Outcomes for Plastic Surgeons database and used multivariate regression models to compare interaction between liposuction volume, body mass index and rate of complications. Only 1.5% (69) of the patients experienced postoperative complications. These patients had an average of 2.1 ± 1.8 liters of fat removed and had an average body mass index of 26.5 ± 4.5 kg/m 2 . Overall, they found that patients who experi- enced one or more complications underwent procedures with higher average liposuction volumes (3.4 ± 2.7 liters vs. 2.1 ± 2.7 liters) and had higher body mass indexes (28.2 ± 4.3 kg/ m 2 vs. 26.5 ± 4.5 kg/m 2 ) than patients who did not experience a complication, but there was a decrease in overall complications when increases in lipoaspirate volume were accompanied by increases in body mass index. The threshold at which complications increased most signifi cantly was 103.8ml per unit of body mass index. The study was published in Plastic and Reconstructive Surgery (September 2015). 8 NOVEMBER/DECEMBER 2015 | Med Esthetics Periorbital Support Practices that want to wow their periorbital rejuvenation patients may benefi t from offering homecare products designed to strengthen, moisturize and grow eyelashes and brows.
