How Bellafill WorksBellafill® uses an innovative blend of 2 distinct components to create results that are both immediate and long lasting. Suspended within its smooth collagen gel base are tiny polymethyl methacrylate (PMMA) microspheres. Once it's injected, the collagen goes to work immediately, adding natural-looking volume to soften smile lines or acne scars. Over time, your body naturally metabolizes the collagen — but that doesn't mean your results disappear.How Can Bellafill® Help?Bellafill® also reduces the look of acne scars. Although your acne may be long gone, its scars can hang around. Bellafill® fades these scars by adding volume to them, bringing them to the level of the surrounding skin and keeping them there through 1 year. Bellafill® is the first and only injectable filler that's FDA approved to treat acne scars.
