The appearance of facial wrinkles, lines, or folds is a natural phenomenon during aging. Different scales help classify wrinkles objectively, such as the Facial Wrinkle Scale. Others help classify patients' subjective perspectives, like the Face-Q questionnaire. The application of Botulinum Toxin is the most performed non-surgical aesthetic procedure in the world to treat facial expression lines. The present study aims to compare the efficacy of onabotulinum toxin-A (BOTOX®) and prabotulinum toxin-A (NABOTA®) to treat expression lines in the upper third of the face, based on objective and subjective follow-up, using the FWS scale and FACE-Q questionnaire, respectively.
