6 months after BBL. My butt is still shrinking

Thank you for the question. From your description the shrinking of your buttocks is not from the loss of fat cells, but rather secondary to the weight loss after the procedure. This is causing a loss of fat content within the transferred fat. Transferring the fat cells does not mean that they will not gain and lose fat content in the same manner as before the procedure. I would venture, that if you have any noticeable weight gain in the future, you will notice an increase in your gluteal fat volume.I hope this helps. Good luck.

The fat cells that were injected and survived will shrink in size if you increase muscle mass and lose fat %.
