Dear Roxxane, The simple answer to your question is 'Yes'. That is because fat injection to the butts, do not last beyond 6 - 12 months. Just yesterday, I had a patient who came for butt augmentation consultation for butt implants . She had fat injection to the butts 2 months ago and the fat already dissolved to a degree that made her unhappy and she is planning butt implants. I recommended to her to wait 6 -12 months before getting the butt implants because her present butt size will be reduced dramatically with time and the implants size and shape will have to be adjusted to the final butt size and shape. This story was repeated many times in my practice. Obviously , when you add butt implants to fat injection the cost is much higher. The big advantage of butt implants is that they do not disappear . You have, however, to consult with a board certified plastic surgeon who has lots of experience with butt implants and check the before and after results to make sure that you like the results.Best of luck, Dr Widder
