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.

The aim of this report is to highlight and warn cosmetic dermatologists about the need of a complete and careful examination of any patient that looks for our evaluation, even when they ask only for cosmetic treatments and/or procedures. This is nowadays a very important concern as people and some physicians are involved in an exaggerated search for eternal beauty. This represents a very profitable practice for dermatologists and plastic surgeons. But we should never forget that a dermatologic consultation can be an opportunity to discover an unnoticed dermatosis or signs related to systemic diseases.
