How long can fat be stored before it is injected?

Written by Frank P. Fechner, MD

We like to inject the fat immediately after its harvest. The success of fat grafting procedure depends ultimately on the viability and survival of the fat cells. I do not store fat any longer for later treatments down the road because I prefer optimal fat quality for best fat survival. And it is relatively easy to obtain a little more fat during the next treatment.

Other surgeons may store frozen fat for up to 1 year, recognizing that survival will likely decrease.
