Botox injections are the top non-surgical cosmetic procedure according to the American Society of Plastic Surgeons. In 2007, 4,625,192 Botox injections were given, up from 4,090,517 in 2006. The next in popularity is injections of dermal fillers, at only 1,050,722 procedures in 2007.

How Does Botox Work?

Unlike dermal fillers, which inject some type of substance beneath the skin surface to plump it up or support it, Botox works by paralyzing muscles. The tiny dose is injected into a specific muscle and for a few months prevents that muscle from contracting. It does that by blocking a chemical called acetylcholine which motor nerve endings would normally release into the muscle. In other words, it blocks the brain’s message telling the muscle to contract.

Botox is most often used for frown lines, where it is injected into the small muscle which draws the eyebrows together and downwards (called the corrugator supercilii). By blocking any use of this particular muscle, Botox prevents you from frowning and forming those wrinkles. It is also used to treat horizontal forehead lines and some other face and neck areas.

Non-Cosmetic Uses for Botox

A substance which relaxes muscles and stops them from contracting could potentially have other uses than cosmetic, and in fact Botox is used in ways that don’t receive the publicity of its cosmetic use.

  • Some doctors are using Botox to treat migraine headaches by preventing muscle contractions which create tension. Injections are made into muscles of the eyes, forehead, side of the head and back of the head.
  • Others have successfully used it to reduce excessive sweating in the underarms or palms. By blocking the acetylcholine from being released from nerve endings to the sweat glands, it blocks the message telling the glands to secrete sweat. This use for Botox has FDA approval.
  • Botox has a good track record in reducing the painful muscle spasms of cerebral palsy. It reduces drooling and helps a patient walk by relaxing the calf muscles so that the feet can be placed flat on the floor. Chronic muscle contraction causes the secondary problem of permanent muscle shortening, and Botox can prevent that by keeping the muscles relaxed.
  • Botox is being used for stroke, brain injury and spinal cord injury patients, to relax the chronic stiffness and immobility of affected muscles. This is more effective on smaller muscles like those of the hands than it is on larger leg muscles.

Many of these uses of Botox are off-label, meaning that they are legal but not FDA-approved. A physician can make a professional judgment in individual cases which may not have been specifically tested in the FDA testing phases.
