The results of a Brazilian butt lift are permanent, though your body will continue to change with the normal aging process. Not all the transferred fat cells will survive, but most of them — typically 60 to 80% — will remain in place permanently. The results you see after about six months will be your body’s new proportions. Weight fluctuations can affect the results, especially in the area treated with liposuction, so it’s best to maintain a stable weight through healthy eating and exercise habits.
