Nano-fat grafting for the face and also seeking to get a fat transfer on the hands and feet. Could I do this all at once?

Nano fat is prepared using filters with the goal of creating a liquid that can be injected directly into the skin. Because the process kills most of the fat cells, it is not used for volume. It is used for skin rejuvenation thanks to the stem cells that survive the process. Many plastic surgeons incorrectly use nano fat for volume. The preparation includes harvesting and filtering -- with or without centrifuge. Most of the recent data suggests that centrifuging may harm fat cells -- which doesn't matter so much with nano fat since the filtration kills them, but would impact results (compared to) gentle filtration when using micronized fat for volume.

Yes, certainly these procedures can be done in one session and best of all general anesthesia is certainly not necessary (or even desired).  You will be far safer if this procedure is done under local anesthesia.  If I understand your question correctly yes, you can have STRUCTURAL fat transferred to your hands and feet using standard and well accepted Fat Transfer techniques.  At the same time, it is a simple procedure to convert some of your fat removed to Nano Fat (or emulsified fat) to inject into your face.  Done properly, you should have a wonderful result from these procedures!

Yes, you can do multiple areas at once.  Fat transfer technique is what is important for successful fat transfer. I recommend water-assisted fat harvesting which gives pure fat to transfer and combine with platelet rich plasma (PRP) to get the most viable and sustainable fat cells. I then combine with Sculptra, depending on areas, to get the best outcomes. I recommend getting a formal evaluation with an expert. Best, Dr. Emer
