Thank you for your question and photographs.You may be a candidate for a BBL but it will be more on the conservative side seeing as it appears that you do not have a lot of body fat. The fat can be harvested from multiple areas on your body and injected into the buttocks to build it up and give you that curvier silhouette. Sometimes, this procedure needs to be staged to achieve your cosmetic goals because injecting too much fat at once can increase the chance of more fat cells not surviving. I would recommend scheduling a consultation with a board certified plastic surgeon to have a physical evaluation done to see if you are a good candidate or not. When I perform a BBL, I will evaluate the patient’s body to make sure that they are a good candidate for the Brazilian butt lift. It will also be assessed as to which areas will be liposuctioned. Depending on the amount of fat necessary to fill the buttocks/hip area, multiple donor sites on the body may be considered. After liposuction has been performed, a closed sterile system is used which ensures the fat tissue is never exposed to the air. This keeps it safe and purified for reinjection into the buttocks. Our plastic surgery office uses P188, a triple-wash antibiotic that sterilizes the tissue and separates the healthy fat from any tissue that may not survive the transfer process. I will then reinject the fat to make sure that the layering is done properly, effectively and that the results are smooth and shapely. I do not recommend patients gaining weight for this procedure. You should maintain a stable weight for at least 3-6 months prior to having the procedure done to obtain optimal results. If your weight fluctuates too much pre or post operatively, this can affect your results. If you do not have enough fat to achieve your cosmetic goals, I would consider buttock implants or the combination of fat grafting and buttock implants to achieve your goals.
