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.

Introduction: Complaints about wrinkles and flaccidity in the periocular region are frequent. Blepharopeeling, associated with the Baker-Gordon formula, and the application of ablative fractional CO2 lasers are considered effective options in the treatment of the periocular region. Objective: To compare the techniques, recovery process and results of blepharopeeling and fractional CO2 lasers in the periorbital region. Methods: Comparative split-face study of patients with dermatochalasis and moderate rhytids. Blepharopeeling was applied on the right side of the face, and the fractional CO2 laser was used on the left side of the face. Results were assessed through photographic analysis, measurements of the superior palpebral fold and clinical improvement. Results: Patients (n=11) demonstrated clinical and photographic improvement using both methods. The recovery time was longer for the phenol peeling. No significant differences were observed in the measurements of the superior palpebral fold. Conclusion: While both therapeutic modalities were found to be effective in the treatment of periorbital aging, blepharopeeling produced greater clinical improvement of palpebral flaccidity.
