The cosmetic form of botulinum toxin, often referred to by its product name BotoxÆ, is a popular non-surgical injection that temporarily reduces or eliminates frown lines, forehead creases, crows feet near the eyes and thick bands in the neck. The toxin blocks the nerve impulses, temporarily paralyzing the muscles that cause wrinkles while giving the skin a smoother, more refreshed appearance. Studies have also suggested that Botox is effective in relieving migraine headaches, excessive sweating and muscle spasms in the neck and eyes.
