Butt lift or Brazilian butt lift (BBL) is a plastic surgery procedure performed to give a fuller appearance to the butt area of people with volume loss in the butt area. This process is performed by injecting the fat tissue taken from the person's body into the butt area.

The butt lift process first starts with fat aspiration. In this procedure, fat is usually removed from areas of the body that contain more fat, such as the abdomen, hips or thighs. Then, the extracted fat is processed with a special process and made ready for injection.

The prepared fat is injected into the butt area. The injected fat adds volume to the butt area and provides a fuller appearance. It also improves the shape of the butt area.

Butt lift is usually done under general anesthesia and takes about 2-4 hours. After the procedure, the person can return to their normal daily activities, but there may be swelling and bruising in the butt area. The healing process may vary depending on the person's body type and the amount of fat in the butt area.

Butt lift can also be done in conjunction with other aesthetic procedures. For example, when performed together with tummy tuck surgery, a tighter abdomen and a fuller butt can be achieved. However, butt lift can always be risky. Complications can include infection, bleeding, anesthetic reactions, fat embolism, and loss of sensation in the butt area. Therefore, it is important to consult a plastic surgeon and discuss the risks and benefits before the procedure.
