Fat grafting can be done more than once in the hands. It's generally best to wait at least 6 months in between sessions.There are a few reasons this procedure would be repeated. If not enough fat was injected, or there was more re absorption of fat than was expected another treatment should improve the results. The procedure is done by removing fat from one area of the body with micro-liposuction techniques, concentrating the fat by eliminating anesthetic fluid, oil, and blood cells, and injecting the fat in a gentle and sterile manner with fine tubes (cannulas). It usually takes about 2-3 weeks for the swelling to settle after the procedure. It can be performed under local anesthesia or sedation. Fillers are an alternative to fat injections that don't last as long but also don't require much recovery time.
Fat augmentation of the Hands is something we developed more than 35 years ago. If properly done it should only need to be done at one time. The initial swelling will go away and the fat that remains will be permanent. See a very experienced injector for this
