How does botox work ?

Biology
1 answer:
denis23 [38]4 years ago
4 0

Botox blocks signals from the nerves to the muscles. The injected muscle can no longer contract, which causes the wrinkles to relax and soften. It is most often used on forehead lines, crow's feet (lines around the eye) and frown lines. Wrinkles caused by sun damage and gravity will not respond to Botox.
