BOTOX, short for botulinum toxin, is a neurotoxic protein derived from the bacterium Clostridium botulinum. In cosmetic applications, it is used to temporarily paralyze or relax targeted facial muscles. By inhibiting the release of acetylcholine, a neurotransmitter responsible for muscle contractions, BOTOX effectively reduces the appearance of wrinkles and fine lines caused by repetitive facial expressions. This mechanism of action makes BOTOX particularly effective in treating dynamic wrinkles, such as those around the eyes and forehead.
