Sculptra is different from other fillers. It forms a matrix that your body will fill with its own collagen. Studies show the results last up to 5 years. Filling the top of the glutes will lift a drooping butt, and filling the lateral glute area will fill out the “hip dip.” Sculptra can also be injected directly into cellulite dimples to break up the bands that cause this deformity, smoothing and firming the skin at the same time.
