Introduction: Botulinum toxin is a protein produced by the bacterium Clostridium botulinum. When administered orally in large quantities, it blocks nerve signals from the brain to the muscle, causing generalized paralysis, called botulism. However, by injecting very small amounts into a specific facial muscle, only the impulse that guides this muscle will be blocked, causing local relaxation. In this way, botulinum toxin acts as a blockade of the underlying muscles of the unwanted lines. In recent years, there has been an increase in the use of botulinum toxin in aesthetic procedures and knowledge about it is of great importance. Aim: The aim of this study was to demonstrate the use of botulinum toxin in aesthetic procedures. Methodology: This is a literature review study. Results: Botulinum toxin has been widely used in aesthetic procedures to temporarily reduce painful wrinkles, such as expression lines on the forehead, around the eyes (crow's feet) and between the eyebrows (glabella). Botulinum toxin is also used to treat gummy smiles, hyperhidrosis (excessive sweating) and facial asymmetry. Its aesthetic use provides a rejuvenated appearance and softens the marks of facial ageing. Clinical studies have shown positive results in terms of improved facial appearance and increased patient satisfaction with botulinum toxin procedures (CARRUTHERS, A., & CARRUTHER, J 2009). Conclusion: Botulinum toxin is extremely important in aesthetic procedures and requires a great deal of attention from professionals, as it brings great benefits if used correctly and in the correct dose.
