How Long Does Fat Last After Harvesting?

The harvested fat must be grafted in a few hours or most of it will die. Frozen fat is not recommended as a large percent of the cells die as well. Best to use fresh fat with each graft.

Frozen Fat Transfer - Possible but not in your best interest. First of all it must be done in absolute sterile conditions using a protocol and utilizing a company that specializes in stored fat.

Freezing fat is not a standard procedure and should be viewed as experimental. In short, is not in your best interest. The reason is that as a rule, the longer the fat is outside your body the more of a chance there is of fat cell death, infection from contamination, and less chance of survival. The best chance for maximum fat survival is immediate fat transfer. Even then there is incomplete survival.

 

Remember there is Zeltiq CoolScultpting which essentially cools fat in your body externally to make fat cells die early. It therefore doesn't make sense that cooling fat will also increase the survival of fat. See a board certified plastic surgeon with experience in this technique

Fat that is harvested for transfer should be used right away. Stored fat has unpredictable survival and there is always a concern about bacterial contamination or "sterility" of a biological product stored under conditions which have poorly defined industry standards -- especially in a private clinic setting.
