What are butt implants? 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.
