Filler injections can be used to restore volume and fullness to the skin to correct moderate to severe facial wrinkles and folds, such as nasolabial folds. One of the more popular filler injections is Restylane, which has been in use since 1996, though a variety of other products are also available. Treatment results usually last approximately six months or even longer.
