Botox® Cosmetic is a purified protein produced by the Clostridium Botulinum bacteria. Botox injection treatment is quick and results usually last for three to six months. It temporarily inactivates the muscles that produce wrinkles, thereby causing lines to disappear or diminish dramatically. It usually takes a few days after the injection to notice the wrinkle-smoothing effect. Some of the common areas treated with botox include crow’s feet, frown lines, laugh lines and forehead wrinkles.
