Botulinum toxin injections are popular for improving the appearance of dynamic facial wrinkles, those wrinkles caused by the contraction of underlying muscles. Botulinum toxin injections block certain chemical signals from nerves that cause muscles to contract. This temporarily relaxes the facial muscles that underlie and cause wrinkles, including forehead furrows and lines around the eyes. Botox Cosmetic, Dysport, Jeuveau, and Xeomin are all brands of botuliunum toxin approved for use in the U.S.
As skin ages, it begins to lose collagen filled with hyaluronic acid (HA). Collagen and HA add structure and volume to the face. With age, collagen and HA deplete causing skin to sag and wrinkle. HA dermal fillers are smooth injectable gels made from naturally occurring HA. HA dermal fillers add volume to the face and can stimulate collagen production. HA dermal fillers plump the skin, adding a subtle lift. The most common areas treated with HA dermal fillers are the lips, cheeks, and folds around the nose and mouth.
