Hi bambi07. Just checking up on you to see if you had the procedure done. I too am interested in fat grafting, fat taken from my stomach and injected into my face. I too am thin, so my face is hollowing out. I am 57 years old, at this age I feel my face is very drawn looking. I live in the San Francisco bay area, currently in the process of finding doctors who perform this procedure. If you have time, I'd love to hear how it went for you!
