Butt Lift with sculptra: 

Sculptra® is an injectable dermal filler made of a biocompatible synthetic material called poly-L-lactic acid. Sculptra® works to increase volume by stimulating the body’s natural collagen production. Increased collagen can improve the structure and elasticity of skin as well as add or replace fatty tissue. A Sculptra® butt lift, sometimes called a “liquid butt lift”, can give a more plump, round look to a flat derriere or add lift and boost a booty that has begun to sag with age.
