Cosmetic Botox is a slightly altered version of botulinum toxin, which is a neurotoxin produced by the Clostridium botulinum bacterium. It paralyzes muscles by interfering with nerve impulses.
Medically, it was originally used to treat overactive muscles that spasmed frequently. It can also be used in the manner you describe, specifically to relax the facial nerve.
