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: Patients often request anti-aging treatments of the perioral and periorbital regions. Most of the time, it is necessary to use a combination of procedures, so the result meets the patient’s expectations.
OBJECTIVE: This is a prospective, single-center, and comparative study assessing the rejuvenation of the perioral and periorbital regions after treatment with medium depth chemical peel using phenol 88% with or without the previous application of botulinum toxin.
METHODS: Sixteen patients underwent regional peel with phenol 88%; eight received botulinum toxin application two weeks before. The assessment was conducted using standard photographs and evaluation scales by doctors and patients.
RESULTS: The overall evaluation by doctors and patients on the 45th day was considered excellent or good for all patients, with little advantage for combined treatment in the periorbital region.
CONCLUSION: Combining these two relatively low-cost procedures, often overlooked by dermatologists, resulted in a significant improvement in the changes related to aging in these areas.

BACKGROUND: The increased demand for cosmetic facial treatments is a universal reality, with Brazil being the second country in the world that performs them the most. Quality of life questionnaires can help assess results more objectively and reveal data not yet explored in the scientific literature. For this, the process of translation, adaptation and validation of questionnaires is necessary for the universalization of data.
OBJECTIVE: To translate, adapt and validate a specific questionnaire for the assessment of facial cosmetics procedures into the Portuguese language spoken in Brazil.
METHODS: After choosing the SROE (Skin Rejuvenation Outcome Evaluation) questionnaire, the translation process started. A literal translation was performed, with subsequent synthesis of the versions. After, reverse translation and final validation by a team of experts were carried out. The data obtained were statistically analyzed for validation.
RESULTS: The final version was called "Avaliação dos Resultados de Rejuvenescimento da Pele" (ARRP). The Cronbachs a resulted in values above 0.70, showing good internal consistency. The Intraclass Correlation Coefficient was 0.995 (p<0.001).
CONCLUSIONS: The values obtained validate the ARRP questionnaire, translated into Brazilian language and culture, which aims to evaluate the results and impact on the quality of life of facial cosmetics procedures.
