Botox is a brand name for a toxin produced by the bacterium Clostridium botulinum. It's used in medicine to treat certain muscular conditions and cosmetically to remove wrinkles by temporarily paralyzing muscles.
Botox injections work by blocking signals from the nerves to the muscles. The injected muscle can't contract, which causes wrinkles to relax and soften. It's commonly used to treat forehead lines, crow's feet, and frown lines between the eyebrows.
When administered by a trained medical professional, Botox is generally safe. However, like any medical procedure, it carries some risks and potential side effects. Common side effects include bruising, swelling, or temporary weakness in nearby muscles.
