I have heard that you have to get a BBL done twice for the fat to take. Is this true? (Photo)

Thank you for your question. If done correctly, the results of a Brazilian Butt Lift should remain as long as your own body's natural fat deposits.  However, at  any given procedure, your surgeon can only inject and your body will only allow a limited amount of fat to survive and become a permanent part of your buttocks.  One treatment is usually adequate, but for more significant enhancement, more treatments might be needed.  As with any fat grafting procedure, the extracted fat needs to be treated before being transferred into the buttocks. And, as with any fat grafting procedure, some of the fat is reabsorbed during the recovery phase. However, the rest should remain permanent. I would strongly recommend finding a board certified plastic surgeon who is experienced in this procedure, since the technique of how the fat is injected makes a big difference as far as the quality and longevity of the results. Good luck! 

I tell patients that the fat injected will not take 100%. Initially you also have swelling which will settle over time and so the final results may take a several months to see. Some patients want more fat after this,and often if there is more fat to harvest, it can be accomplished. But, it is the exception rather than the rule.
