Brazilian butt lift, or BBL, uses liposuction to remove stubborn fat from the patient’s own body. A small incision is made and a cannula is inserted into the layers of fat. A solution of saline, lidocaine and epinephrine, along with the motion of the cannula, breaks up the fat cells. The fluid and fat cells are removed through a vacuum attached to the cannula. The fat is processed, purified and placed in the buttocks to give a more contoured and slimmer look. Since the transferred fat comes from the patient's own body, BBL carries a low risk of infection or rejection from the body. The injected fat provides a more curvy shape.
