One of the benefits of a Brazilian Butt Lift is that the fat grafted to the area can survive and create permanent enhancement. However, not all of the fat that is transferred to the buttocks will survive, which is why surgeons typically overfill the area slightly, to compensate for these cells that will not survive the transfer. After about six months, the fat cells that will live are typically established, and results shouldn’t change much after this. Although the results are considered permanent, aging, weight gain or loss, and other factors can influence the appearance of the buttocks later in life.
