Botox Procedure Overview Botox has become the most common cosmetic procedure in plastic surgery. Botox is purified injectable Botulinum Toxin which causes temporary improvement of facial wrinkles. The injected facial muscles become temporarily paralyzed at the site of injection. The kinds or wrinkles caused by facial animation are temporarily improved; most commonly in the crows feet area and the area between the brows. The effect lasts for approximately four to six months and can be repeated. Risks of the procedure include incomplete relief of wrinkles, double vision and eyelid droop. These risks can be minimized by trusting only a qualified physician to perform the procedure.
