The cosmetic form of botulinum toxin, known as Botox®, is a purified protein injectable filler that is FDA-approved for the temporary treatment of frown lines. This simple, non-surgical injection is also commonly used to temporarily reduce or eliminate forehead creases, crow’s 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 suggested that botulinum toxin can also be effective in relieving migraine headaches, excessive sweating and muscle spasms in the neck and eyes.
Doctors have been using Botox for years to successfully treat wrinkles and facial creases. Botox is a brand name of a toxin produced by the bacterium Clostridium botulinum. There are also other brand names, such as Dysport and Xeomin.
These are injectables that help smooth so-called dynamic lines -- such as forehead furrows and crow's feet caused by frowning and smiling -- by blocking muscle contractions under the skin.
