Botox, short for botulinum toxin, is a neurotoxin derived from the bacterium Clostridium botulinum. When used in small, controlled amounts, it temporarily relaxes the muscles responsible for wrinkles and fine lines. This process smoothens the skin, offering a rejuvenated and youthful look. While Botox is primarily associated with aesthetic purposes, it is also used to treat medical conditions such as migraines, excessive sweating, and muscle spasms.
