Hello jasmor, thank you for your question regarding enhancing the shape of your buttocks after biopolymer removal. First off, congratulations on undergoing the biopolymer removal five years ago—a significant step toward better health and safety. Considering your desire for a more natural shape in your buttocks, a Brazilian Butt Lift (BBL) or autologous fat transfer is indeed an excellent option for reconstruction and it’s my preferred method after biopolymer removal. This procedure involves harvesting fat from areas such as your abdomen, back, arms, or thighs, and transferring it to the hips and buttocks. This not only helps in achieving a more aesthetically pleasing and natural contour but also utilizes your body's own tissues, which can lead to better integration and fewer complications compared to foreign materials. Thank you for your question regarding enhancing the shape of your buttocks post-biopolymer removal, and I wish you the best in your journey toward achieving the results you desire. Sincerely, J. Timothy Katzen, MD, FASMBS, FICS Plastic Surgeon
