After a Brazilian Butt Lift (BBL) you will experience a series of changes with your newly transferred fat cells. You will immediately notice your booty will be stiff and hard. As the swelling decrease so will some volume because the body reabsorbs some of that fat. That doesn't mean you'll need another BBL round. At around 3-4 months post-op your booty will become fuller, rounder and softer and it will fluff out. No need to worry or overwhelm yourself early on the "fluff out" is real just give your body time and the new fat cells to settle in.
