Restylane® is a safe and natural cosmetic dermal filler that restores volume and fullness to the skin to correct facial wrinkles and folds, such as nasolabial folds.

Restylane is the only cosmetic dermal filler made of non-animal-based hyaluronic acid, a natural substance that already exists in the human body. The hyaluronic acid in Restylane is a crystal-clear gel called NASHAT or Non-Animal Stabilized Hyaluronic Acid. NASHA is completely biocompatible with human hyaluronic acid.

Unlike other hyaluronic acid-based products, such as those made from rooster combs, only Restylane is non-animal-based. This quality virtually eliminates any risk of animal-based disease transmission or allergic reaction.

Based on clinical studies3, Restylane treatments produce a very low occurrence of adverse events. The most commonly reported side effects were temporary redness and swelling at the injection site. These effects typically resolve within two to three days.

Restylane® has been used in more than 1.5 million treatments in over 60 countries to correct a variety of wrinkles and to enhance the appearance of the lip border. It is currently approved in the U.S. for the treatment of facial wrinkles and folds, such as nasolabial folds, which are the lines from the nose to the corners of the mouth.

Clinical studies have shown the average Restylane® treatment results can last six months or even longer. The unique NASHAT technology helps maintain the cosmetic effect until the injected material is nearly gone.
