Dermal fillers include products such as Restylane, Perlane, and Juvederm.  Fillers are able to replace lost volume in the skin to soften lines and wrinkles in the face(such as nasolabial folds) and enhance features such as the lips or cheeks.  These products are naturally occurring hyaluronic acids that are synthetically reproduced and then modified to prolong their effect.  This means they are safe and effective.
