Thank you for your question . The results will depend on the experience of your surgeon and how your belly was post up of your procedure. Many surgeons, including myself, offer online virtual consultations where you send us your photos and we can estimate the cost. I, like many surgeons, also offer free consultations so that you can be examined and given the most accurate quote. Choose a board certified plastic surgeon who has done a ton of Brazilian Butt Lifts and has privileges to do this surgery at a local university hospital. This says his credentials have been checked out by fellow Drs. All surgeries carry risk, talk to your plastic surgeon and choose one wisely.
When fat is harvested from the abdomen it should not impact the umbilicus to any great extent. But I will say it depends upon what your abdomen looked like before and how much fat is harvested.
