BELOTERO BALANCE® is a prescription injection that is approved to temporarily smooth out and fill in moderate-to-severe nasolabial folds (the folds or wrinkles that go from the side of the nose to the corner of the mouth). BELOTERO® is a hyaluronic acid (HA) injectable filler that completely integrates into the skin tissue. While some fillers are designed to rebuild facial volume and structure, BELOTERO BALANCE specifically treats moderate-to-severe etched-in lines and wrinkles such as vertical lip lines above and around the lips.
