Bellafill® injectable dermal filler is a unique product indicated to correct smile lines (nasal labial folds) as well as acne scars. It is a smooth, collagen-based dermal filler comprised of 80% collagen and 20% polymethylmethacrylate (PMMA) microspheres. When injected, Bellafill's collagen component immediately adds volume below acne scars or wrinkles to lift them to the level of the surrounding skin. The PMMA microspheres form a matrix that supports production of collagen, which replaces the injected collagen over time. This matrix provides lasting support the skin needs for acne scar and wrinkle correction. In fact, in US clinical studies, Bellafill correction was maintained throughout the course of the 12-month studies.
