Liquid facelifts, or injectables, and non-surgical facelifts have stimulated a great deal of interest. In limited scientific studies, stem cells mixed with hyaluronic acid have been injected into the laugh lines and shown to provide reduction in the depth of the creases. Further studies are needed, but there is a theoretical consideration that fat itself has stem cells within and therefore have unique aging prevention qualities. Fat injected in to the face or the back of the hands seems to do more than just feel in the crease- it can make the skin look younger. Fat grafting has become the treatment of choice for non-surgical face-lifts.
