APLICABILIDADE DA TOXINA BOTULÍNICA: ATUAÇÃO DO BIOMÉDICO

Botulinum toxin (BT), a neurotoxic substance produced by the bacterium Clostridium botulinum, has stood out as one of the most widely performed non-surgical aesthetic procedures worldwide due to its effectiveness in blocking acetylcholine release, leading to temporary muscle paralysis. This study aims to analyze, through a narrative literature review, the applicability of BT in both aesthetic and therapeutic procedures, with emphasis on the role of biomedical professionals. The research was conducted using indexed scientific databases, considering publications from 2019 to 2025. The results highlight the extensive use of type A BT in facial aesthetics, treatment of gummy smile, hyperhidrosis, rejuvenation, and keloids, as well as in therapeutic contexts such as dystonias, bruxism, and migraines. The study also discusses safety criteria and potential adverse effects associated with its application, ranging from mild bruising to rare systemic reactions. Moreover, it underscores the role of the aesthetic biomedical professional as a qualified practitioner, whose regulated practice contributes to the efficacy and safety of the procedure. It is concluded that BT represents a versatile tool in promoting well-being, provided it is administered by qualified professionals and in accordance with established legal and technical standards.
