What are butt implants? January 25, 2023 Buttock implants are specialized silicone implants used to improve the overall shape, size, and feel of the buttocks. Butt implants are nearly always made from silicone gel, unlike breast implants that are also available in saline and silicone variants. The silicone gel inside our buttock implants provides a soft, yet firm form that allows them to keep their original dimensions even after insertion. Dr. Cara Downey and Dr. Jamal Bullocks are board-certified plastic surgeons with nearly 15 years of experience with plastic and cosmetic surgery. Over this time, they have crafted many successful and life-changing butt implant surgeries every year for patients in the greater Houston area.
