Introduction: The botulinum toxin is a valuable option for the treatment of dynamic facial wrinkles. The Lanzhou botulinum toxin type A (LBTX-A) was introduced in China in the early 90’s and approved in Brazil in 2003. Objective: Evaluate the efficacy and tolerability of LBTX-A for the cosmetic treatment of dynamic wrinkles of the upper face. Material and Methods: In a prospective, open-label, multicenter study, 110 subjects of both sexes (aged from 25 to 65 years) were treated with a total of 53 U of LBTX-A each, distributed in fi fteen sites in the frontal, corrugator, procerus, orbicular ocular lateral muscles. The patients were reviewed 7 times within 180 days. Efficacy was assessed by electromyography, photographic analysis and the investigator’s and patient’s opinions. Tolerability was assessed by the incidence of adverse events.Results: Two weeks post-injection, 94% of the treated patients considered the result as good or excellent. Results lasted 90 days in most cases. After injection, most patients reported mild or no pain, and minimal and reversible side effects as facial edema (6 patients), stuffiness feeling (3 patients) and eyelid ptosis (2 patients). Conclusions: We conclude that LBTX-A is effi cient and well tolerated for the treatment of dynamic facial lines.

Introdução: Gynoid lipodystrophy, popularly known as cellulite, is regarded as an issue of cosmetic concern to millions of women. Recent studies have shown that garlic extract can be useful to enhance lipolysis and decrease lipogenesis. Objective: The primary objective was to determine if topical application of a lotion containing garlic (15 ppm) would improve cellulite parameters. Material and Methods: 50 women were treated topically with a lotion containing 15 ppm of garlic. All patients treated one leg, did not treat the other one and were valuated (measurement of thigh diameter) before and in biweekly intervals up to 8 weeks after the onset of treatment. On eight of these subjects, microcirculatory parameters [red blood cell velocity in arterioles and venules (mm/s), functional capillary density (FCD), diameter of the dermal papilla (µm) and capillary diameter (µm)] were measured using the Cytoscan®. The exact thigh local for these measurements was marked in a transparent sheet, to assure that all of them were performed on the same place. Six women that performed the Cytoscan® exam group were also evaluated by ultrasound to determine the thickness of subcutaneous tissue. Results: after garlic treatment, there was a reduction of 1.62 cm on the diameter of the treated thigh (p < 0.001) without significant changes on papilla and capillary diameters, but FCD improved significantly (p < 0.03) and epidermis and dermis thickness decreased after topical garlic treatment. b>Conclusions: Garlic extract at a concentration of 0.0015% showed significant clinical, microcirculatory and ultrasonographic improvement of cellulite.

Introduction: Skin photoaging can be treated with ablative therapies that cause immunological changes to the skin. Objectives: To evaluate the results of chemabrasion in the treatment of perioral wrinkles and the change in number of Langerhans cells. Material and Methods: Application of 35% trichloroacetic acid followed by manual dermabrasion using waterproof sandpaper, in 12 female patients with perioral wrinkles and results were then examined 30 days and 1 year later. Immunohistochemistry was used to measure Langerhans’ cells which were counted before treatment and 1 month post-treatment. Results: Improved perioral photoaging and reduced number of Langerhans’ cells (p = 0.002) were seen in all patients. Conclusions: Chemabrasion provides effective results in the treatment of perioral wrinkles but Langerhans cells remain low for 30 days after therapy.
