The cosmetic form of botulinum toxin is known as the product name Botox® Cosmetic. Botox is a popular non-surgical injection that temporarily reduces or eliminates frown lines, forehead creases, crow’s feet near the eyes and thick bands in the neck. It can also be used to elevate the eyebrows in selected cases. The toxin blocks the nerve impulses, temporarily paralyzing the muscles that cause wrinkles while giving the skin a smoother, more refreshed appearance. Botox has also been used to improve excess sweating in the armpits (hyperhidrosis). It can also improve the severity and frequency of migraine headaches.
