a popular cosmetic treatment used to reduce the appearance of fine lines and wrinkles. Botulinum Toxin is a neurotoxin produced by the bacterium Clostridium botulinum, and it works by temporarily paralyzing specific muscles.
Mechanism: Botulinum toxin blocks the nerve signals to the muscles in which it is injected. This prevents the muscles from contracting, which smooths out wrinkles and lines caused by repetitive facial expressions.
