Botox and Dysport are both injectables that work by decreasing carefully
selected muscle contraction. One of the major causes of wrinkling on the
face is repetitive facial movement. Botox and Dysport lessen the strength
of the contraction (and can inhibit it completely with enough units) to
soften lines. Dr. Dempsey performs all cosmetic injections herself.
