Good Morning E.haddock Thank you for your question. The answer to your question would be determined on your pre-op testing to be sure that you are healthy enough for the fat transfer to the buttocks region. This procedure of a BBl using fat transfer or, fat grafting, is usually done in combination with full body liposuction or some liposuction. Your blood work as well as a full ECG must show that you are healthy enough to undergo such a procedure. Also, if you have already had liposuction, and have maintained your weight since the procedure back in 2007, there may no longer be sufficient fat stores or, "good quality fat" to harvest during liposuction for the fat transfer to the glutes. This also would depend on how much volume you were looking to add. If there isn't enough fat stores then, perhaps you would need to have gluteal implants instead to achieve your desired final results. I hope this helps and wish you the best!
