BOTOX® is the brand name of a toxin produced by the bacterium Clostridium botulinum. In large amounts, this toxin can cause a form of muscle paralysis known as botulism, which is usually associated with food poisoning. Even though one of the most serious complications of botulism is paralysis, scientists have discovered a way to use it to human advantage. Small, diluted (weakened) amounts can be directly injected into specific muscles, causing controlled relaxation of the muscles.
How it works?
Botox blocks the signal from the nerve to the muscles. The injected muscle can no longer contract (tighten) as forcefully, which causes the wrinkles to relax and soften.
Botox can be used on the forehead lines, frown lines, crow’s feet, bunny lines (lines in the nose), chin (for dimpling), skin bands on the neck, and around the mouth (for smoker’s lines and down-turned corners of the mouth). Wrinkles caused by sun damage and gravity often will not respond to Botox. It is important to re-emphasize that Botox is NOT a facial filler (that is, it does not fill existing wrinkles) – it merely relaxes the muscles that are creating those wrinkles.
Botulinum toxin is currently approved for the following therapeutic applications:
Botulinum toxin is also used off-label (not approved) for:
Botulinum toxin is sold commercially under the names:
