Why does my butt looks so flat and saggy 7 weeks after BBL? (Photo)

Thank you for your question and photos. Based on this single view photo, you had a square shaped buttocks before and after your BBL. The sculpting of the back looks good, but unfortunately the buttock’s shape is altered minimally. A BBL procedure is as much a technical as an artistic operation. Allow yourself to heal at least for six months, but you will need another surgery to give you the desired result. You will need the upper square shaped hip/ buttock area rounded off, lateral thighs will need to be addressed, upper buttocks shelves created and increased projection. Hopefully, you have enough fat left to achieve all these. Over the next 3 months, your buttocks will get smaller, but you will not have improvement in shape.See a board certified plastic surgeon experienced in advanced body sculpting techniques for an in person consultation/evaluation. You cannot afford another failed procedure. Good luck.

It would be helpful to know the amount of fat injected as I revise about 75% of BBLs due to conservative removal and injection.

Thank you for your pictures and questions. It looks like you have had some nice improvement in the areas of liposuction. The buttock shape however, is not what you had hoped for. None of us know the details of the procedure or the techniques used. However, with buttock fat grafting, the success of the procedure depends on many factors. While things can look great right away, the fat will resorb with time and likely will not improve with additional time. You need to discuss your concerns with your PS and review your expectations compared to the outcome.
Hope this helps!

We know that after fat transfer with a BBL that is standard for fat volume to go away for 3 to 6 months after surgery. This means your booty will be the biggest it is going to be immediately post op then shrink slowly for 3-6 months. The majority of the volume loss occurs in the first 4-6 weeks after surgery then more slowly up to 6 months. The volume of fat lost is ~30-50%. Some surgeons also inject a lot of "fluid" with their fat and therefore more can be lost. Unfortunately, your booty will continue to change from now to the 3 months mark but now in the way you are wanting. It is going to get smaller not bigger. From the one view that you gave us in your photos, the overall shape is not much of an improvement. Obviously, none of us were there when you shared your expectations with your PS and when they informed you of what is realistic in their hands. The areas of liposuction look dramatically different but the overall shape of your buttocks is not as round as most desire. Give things time to settle in (at least 6 months) then you can consider a revision if you have fat left on your body for harvest.
