Buttock augmentation, or gluteal augmentation surgery, increases the fullness and roundness of the buttocks and improves the overall balance of the area through the placement of implants or fat transfer which is commonly known as a Brazilian butt lift (BBL). Butt implants are surgically inserted into the buttocks to add size and shape to the area. Patients with sagging skin can enhance and firm their buttocks with butt lift surgery. A butt lift can be performed in combination with other procedures like an abdominoplasty to achieve more comprehensive body contouring.
