Restylane contains hyaluronic acid in the form of a crystal-clear gel. It is injected into the skin to lift the lip, wrinkle or fold. Once in your skin it creates volume, resulting in a healthy and vital appearance. When injected into the lip it can restore a more natural and/or sensuous look. In contrast to other biodegradable implants, Restylane is not extracted from animals, which means no risk of an allergic reaction. Therefore, it is perfectly safe to use instantly without pre-testing.
