Botox® Cosmetic and/or Dysport are prescription medicines that work by temporarily relaxing the facial muscles that cause the wrinkling of the facial skin, thus producing a smoother, more softened appearance in the skin. They are used to improve the appearance of: frown lines between the eyebrows, fine lines above the lip, "crow's feet" on the sides of the eyes, heavy forehead furrows, skin bands on the neck. Botox and/or Dysport injections are relatively pain-free and an average treatment takes 15-20 minutes. Results for some individuals can take up to two weeks to fully peak. Side effects may include minor bruising at the injection site.
