Human: I've heard that a lot of people are getting Botox treatments for wrinkles, but I'm not sure what it is. Assistant: 
Botox injections are a popular cosmetic procedure that temporarily reduces the appearance of facial wrinkles and fine lines. The treatment involves injecting a small amount of a purified protein called botulinum toxin into muscles in the face. This blocks the release of neurotransmitters from nerve endings which causes temporary paralysis of the muscle. As the muscle becomes paralyzed, the wrinkles appear to be reduced or even completely eliminated.
