Restylane is the first cosmetic dermal filler made of non-animal-based hyaluronic acid. Hyaluronic acid is a natural substance that already exists in the human body and is used to provide volume and fullness to the skin. The hyaluronic acid in Restylane is a crystal-clear gel called NASHA, or Non-Animal Stabilized Hyaluronic Acid. NASHA is biodegradable and completely biocompatible with human hyaluronic acid.

It has been used safely by dermatologists and plastic surgeons since 1996 worldwide. Because Restylane is non-animal-based and fully biocompatible, allergy testing is not required. There is virtually no risk of animal-based disease transmission or allergic reaction. The most commonly reported side-effects were temporary redness and swelling at the injection site. These effects typically resolve within two to three days.

Studies have shown that the average treatment results last six months or even longer. The unique NASHA technology helps maintain the cosmetic effect until the injected material is nearly gone.

Restylane lasts twice as long as collagen, so treatments are typically scheduled twice a year. Evidence shows that having a touch-up treatment before the product has fully dissipated will enhance the lasting effect.

Restylane is injected directly into the skin in tiny amounts by an ultra fine needle, resulting in minimal discomfort. The procedure is simple and convenient, and results are practically instantaneous. To optimize your comfort during the short procedure, your physician may anesthetize the treatment area.
