Two cubic centimeters of fat has been found to have more than 1.2 million adult stem cells. In areas that have been grafted with fat the overlying skin improves in all aspects, including thickness, texture, etc. We have a process where fat is deliberately broken down into a liquid, which is then injected subcutaneously.
The distortion to the skin caused by doing this disappears in a few days. Long term, the overall condition of the skin is improved. The improvement is thought to be secondary to the stem cells that were released from the fat.
