Botox®, the cosmetic form of botulinum toxin, is a popular non-surgical injection that temporarily reduces or eliminates frown lines, forehead creases, crow's feet near the eyes, and wrinkles and bands in the neck. When Botox is injected, it blocks nerve impulses, temporarily paralyzing the muscles that cause wrinkles while giving the skin a smoother, more refreshed appearance. Botulinum toxin injections are also used to treat migraines, excessive sweating, and other medical conditions.
