Restylane and Juvederm are facial fillers used to help reduce the signs of aging without surgery. These substances are made of hyaluronic acid, a naturally occurring substance in the body. Restylane and Juvederm are two different brands of hyaluronic acid designed for injection under the skin. They help fill hollows in the face which result from aging, such as lines under the eyes (also known as tear trough deformity), smile lines and marionette lines.

The effects of treatment fade slowly over time, with most patients requesting retreatment about every six months. One of the most requested uses of Restylane and Juvederm is to provide a more full, plump appearance to lips. This type of treatment usually lasts about three months.
