As most of the other surgeons have stated, three days after fat injection is far too soon to comment on the results. The good news is that most of the fat placed will be gone.
Can fat transfer be reversed? Yes, but it is very difficult in certain area. Any facial filler, be it fat, Radiesse, etc. is difficult to reverse with the exception of Restylane (HA family).
The fat which has been placed was most likely placed in multiple layers throughout the face with very small amounts (microfat graft, FAMI, etc). Trying to remove a small amount of fat that has become integrated with your body is very difficult.
Frequently patients do not complain about the amount of fat but small hard areas which they can palpate. Steroid injections may be a good place to start, but not earlier than one year.
