The Cellfina® System 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 in as little as three days. This one-time cellulite treatment is performed at a doctor’s office in less than an hour.
