Is it possible to not have enough fat for fat injections for my face?

Yes, it is very possible to not have enough fat for fat injections for the face.Many patients who require volume augmentation in the face are very thin or perhaps an athlete with little body fat.  In these instances, fillers such as Sculptra, Voluma, and other syringe based filler are excellent alternatives to fat transfer (augmentation).  However, if you are lean but have enough fat to transfer the fat typically survives very well in the recipient areas if good techniques are utilized.The attached link provides more information.I hope this helps.

If you do not have any squeezeable fat it is unlikely you have any to harvest for facial injections and fillers like bellafill, sculptra, or radiesse would be useful for you if you want longer term filler options.  see an expert for an evaluation.  best, Dr. Emer.

You typically don't need a large volume of fat for facial grafting.The best way to assess and give true advice would an in-person exam.Please see a board-certified plastic surgeon that specializes in aesthetic and restorative surgery.best of luck!Dr Schwartz
