Use of Onabotulinum Toxin Type A in Aesthetic Medicine in Mexican Patients: Satisfaction with a Full-Face Approach

Background. The use of botulinum toxin type A (BoNT-A) for aesthetic purposes to improve signs of facial skin aging has significantly increased. Full-face treatment with onabotulinum toxin type A (Botox®) is a technique used to rejuvenate facial appearance by injecting small doses of BoNT-A into multiple facial areas. There is insufficient published evidence to support the full-face use of onabotulinum toxin type A in the Mexican population. Objective. This study aimed to evaluate the satisfaction of Mexican patients undergoing full-face treatment with onabotulinum toxin type A. Material and Methods. A retrospective study involving 34 patients who received full-face treatment with onabotulinum toxin type A between February 2022 and March 2023. Patient-reported outcomes regarding treatment satisfaction (GAIS) were assessed. Evaluations were performed on the day of the application (day 0) and 15 days after the application. Results. Data from 34 subjects (6 men and 28 women) were analyzed. The mean age of the population was 44.7 years, with a range from 31 to 73 years. The treated areas included glabella, forehead, periorbital wrinkles, nasolabial lines, nasal tip, gingival smile, chin, masseter, and marionette lines. A total of 100 units were administered per treatment to each patient; 79.6 % of patients reported perceiving significant improvement or improvement; 93.3 % perceived some degree of improvement. Conclusions.The full-face treatment with botulinum toxin type A is satisfactory. In the study population, no adverse events were documented during the 15-day follow-up.
