Neurotoxin or Botulinum Toxin, is a neurotoxic protein produced by the bacterium Clostridium botulinum. It is used for both medical and cosmetic purposes. Botox works by temporarily blocking nerve signals to specific muscles, causing a temporary paralysis or weakening of those muscles.

Botulinum injections reduce the appearance of wrinkles and fine lines on the face. It is commonly used to target dynamic wrinkles, which are formed by repeated facial muscle contractions over time. Botulinum injections can temporarily relax the muscles responsible for these wrinkles, resulting in a smoother and more youthful appearance.
