With the advent of injecting fat into other parts of the body,  It was observed that a large percentage of the fat that was injected was destroyed, transforming into liquid fat which was progressively reabsorbed by the body. However, it was found that potential multiple stem cells emerged from this destroyed fat, which could be transformed into any type of body cell through the process of differentiation. It began to be observed that where the fat was injected, there was not only an increase in volume, but there were also changes in the texture and turgor of the skin in the area.  Later it was discovered that these stem cells, derived from fat, were responsible for changes in the quality and texture of the skin.

​

With this in mind, we proceeded to try to rejuvenate the hands by injecting fat that is obtained  of the patient's body, being able to be from the abdominal area, the inner part of the thighs, the flank area, fat that once obtained, is prepared and injected using the micro tunneling technique, injecting the entire back of the Even hands and fingers, in volumes high enough for stem cells to be produced, which produce on the skin on the back of the hands a production of new collagen, which is responsible for the rejuvenating changes of the skin. This meant that the aging changes of the hands could be corrected with a high degree of satisfaction, becoming today the only really effective method to achieve the rejuvenation of the hands.
