Botulinum toxin is a nerve impulse "blocker". It binds to nerve endings and prevents
the release of chemical transmitters that activate muscles. These chemicals carry
the "message" from the brain that causes a muscle to contract; if the message is
blocked, the muscle doesn't spasm.
Botulinum toxin usually takes full effect within one to two weeks. However, the nerve
endings usually grow new connections to the muscles at sites that have not been
exposed to botulinum toxin. Therefore, treatment must be repeated as directed by
your physician.
It's usually used in cosmetic surgery to reduce wrinkles.
