Thank you for your question and photographs.I would recommend that you schedule an appointment with a board certified plastic surgeon so they can perform a physical examination of your body and see if you are a good candidate for BBL or not. If you have little body fat, which it appears based on your pictures that you do, you may be a better candidate for buttock implants. I do not recommend patients gaining weight prior to surgery because weight fluctuations before or after the procedure can affect your results. For patients who have little body fat I recommend using buttock implants using the XYZ technique which is intramuscular. This would be the best option for you if you do not have enough body fat to harvest for a Brazilian butt lift and will help you achieve a curvier look. Best of luck in your endeavors!Sincerely, James Fernau, MD, FACSBoard Certified ENTBoard Certified Plastic SurgeryMember of ASPS, ASAPS, ISAPS, The Rhinoplasty Society, AAFPRS, OTO/HNS, ASLMS, International Federation for Adipose Therapeutics & Science
