Dermal fillers can soften or eliminate fine lines above the upper lip, smile lines, marionette lines (the creases that extend down from the corners of the mouth), and nasolabial folds (the creases that run from the sides of the nose to the corners of the mouth). Fillers can also add volume the lips and to areas of the face that have hollowed with age, including the cheeks, temples, and under the eyes. Some fillers can lift sagging tissue on the cheeks and jowls.
