After a Brazilian butt lift (BBL), some of the transferred fat cells may die. To improve your results, your surgeon may recommend a procedure called platelet-rich plasma (PRP) therapy. PRP is a concentration of platelets that are found in your blood. These platelets contain growth factors that can help to promote healing and the growth of new tissue. PRP therapy can help to encourage the survival of transplanted fat cells and improve the overall results of your BBL. If you are considering a BBL, be sure to ask your surgeon if PRP therapy may be right for you.
