Finally, a long-term solution for smile lines and acne scars. Unlike hyaluronic acid fillers, which often dissolve within a few months, Bellafill creates a lasting improvement in your skin. With Bellafill, 80% injected collagen is placed below the depression immediately adding volume to the skin to lift and smooth out scars and wrinkles. Bellafill is the only FDA approved injectable to treat moderate to severe atrophic, distensible acne scars on the cheeks. Results may vary.
