Cellfina ™ is the only FDA-cleared minimally invasive, one-time procedure clinically proven to improve the appearance of cellulite for at least two years—the longest FDA-cleared duration for a cellulite treatment. How to get rid of cellulite? It treats the primary structural cause of cellulite—the connective bands woven throughout fat in the thighs and buttocks. These tight bands pull down the skin, creating the puckering you see on the surface of the skin. Similar to a rubber band under tension, once released, the treated skin bounces back to smooth itself out.
