RESTYLANE®, commonly used to fill such areas as the lips and nasolabial folds, is a natural dermal filler containing hyaluronic acid. This substance occurs naturally in the human body. It delivers nutrients and hydrates the skin. RESTYLANE® uses a biodegradable form of hyaluronic acid that is non-animal based. Unlike previously used collagen, no allergy tests are required before treatment.
RESTYLANE® is most often used to correct facial lines like nasolabial folds, marriorette lines and some smile lines. In addition, it is often used to increase volume in patient who are concerned with thin lips. For most patients, RESTYLANE® is effective for four to six months before repeat treatment is required.
Depending on the size of the area to be treated, RESTYLANE® can be applied in combination with other cosmetic procedures. Side effects are usually minor and may include temporary swelling and redness at the injection site.
