A BBL is an abbreviation for Brazilian Butt Lift, which is a cosmetic surgery procedure that involves transferring fat from one area of the body, such as the belly, hips, lower back, or thighs, to the buttocks to improve their shape and projection. The procedure is not an actual "lift" because it doesnt try to raise the buttocks, but rather it increases their volume. The surgery is a two-step procedure that starts with liposuction of a different area, often the abdomen, the flanks, the thighs, or back, and the fat removed from these areas is then injected into the hips and buttocks. The procedure is popular because it can enhance the shape and size of the buttocks without the use of implants, and at the same time, it removes fat from the midsection, where it may not be wanted. The procedure is not without risks, and the fat transfer technique used in a BBL can cause fat to enter the bloodstream and clog major blood vessels, leading to serious complications.
