Restylane® is a dermal filler that is fashioned from hyaluronic acid and contain lidocaine, a local anesthetic. Hyaluronic acid is found naturally in the body and provides volume and fullness to the skin. Injectable hyaluronic acid has been modified to allow for a greater longevity than that found in the skin. It is a safe compound that is degraded gradually by the body over time. The duration of effect from the hyaluronic acid fillers ranges from six months to one year in most cases. Dr. Goldenberg will select the most appropriate filler based on the specific needs of each individual patient. Following the use of an anesthetic agent, if needed, a tiny needle is introduced into the skin. The volume enhancing effect is created by layering the filler in a series of fine tunnels within the undersurface of the skin.
