JUVEDERM ULTRA XC®, BELOTERO BALANCE® and RESTYLANE SILK® are prescription filler injections that are approved to temporarily plump lips to make them more voluptuous, smooth out and fill in acne scars, wrinkles and the tear troughs that form under your eyes (the folds or wrinkles that go from the side of the nose to the corner of the mouth). These are the natural substances our faces are made from, as we use this substance to hold wanter and maintain the space between the cells of our faces. As our skin ages, this hyaluronic acid, along with the natural collagen, elastin and fat are gradually lost from the facial tissues.
