BBL stands for Brazilian Butt Lift, which is a cosmetic surgery procedure that involves transferring fat from other parts of the body, such as the belly, hips, lower back, or thighs, to the buttocks to improve their shape and size. It is not an actual "lift" because it does not try to raise the buttocks, but rather increases their volume. The procedure involves two steps: liposuction to remove the fat from the donor areas, and then injecting the fat into the buttock area. BBL is a popular plastic surgery procedure that can enhance the shape and size of the buttocks without the use of implants, and it can also remove fat from the midsection. BBL is performed by board-certified plastic surgeons who are experienced in this technique.
