THE USE OF BOTULINUM TOXIN TYPE A IN AESTHETICS AND IN THE PREVENTION OF FACIAL EXPRESSION LINES

Abstract

Botulinum toxin type A is used by pharmacists in non-surgical invasive procedures, acting directly on the muscles responsible for expression lines. This article explores its therapeutic properties and its mechanism of action in the prevention of these lines, based on research from academic sources and books. The toxin, produced by the bacterium Clostridium botulinum, inhibits acetylcholine, causing partial muscle paralysis, and is indicated for treating the effects of skin aging. Seven brands are authorized by ANVISA in Brazil. Botulinum toxin type A is widely used in the prevention of expression lines, and its efficacy is proven. Safe application depends on qualified professionals, such as pharmacists specialized in aesthetics.
