I have a very skinny, gaunt face. How do I gain facial fat? (Photo)

I suggest starting sculptra injections and/or other fillers.  IF you are fit you will always have a thinner face and fillers can help to fill this out without having to compromise your body / health.  Best, Dr. Emer.

Thank you for sharing your question. Based on the photo you have provided you appear to be an excellent candidate for dermal fillers and, potentially, fat grafting. I recommend trying a dermal filler first such as Restylane Lyft, Juvederm Voluma or even Radiesse to add volume to your midface. If you are happy with the results, you may want to consider the more permanent option of fat grafting. Fat grafting is a procedure that involves harvesting fat from a donor site such as the abdomen or inner thighs, purifying the fat cells, and then injecting the fat into the desired location on the face. Approximately 50% of the fat injected remains permanently. However, I strongly recommend starting with dermal fillers and considering fat transfer at a later date. Best of luck.  

Facial fillers might be the best way to start. Fat transfer is another consideration as well as submalar implants.
