It is a safe natural cosmetic dermal filler (hyaluronic acid) which already exists in the body. Restylane® will restore fullness to the skin to correct moderate to severe facial wrinkles and folds such as lip line creases and lip corner drooping.
The average Restylane® treatment results last six months or more. Restylane® does not require any allergy testing because it cannot produce any allergic reaction.
The most common side effect, as with any injection, is temporary redness and swelling at the injection site. These side effects typically resolve within two to three days.
