While it is possible to “supercharge” fat grafts with extra, isolated stem cells, there is no solid evidence that this provides a better result than an excellent facelift with fat grafting. I've used fat grafting as a standard part of traditional rhytidectomy for many years, with some really spectacular results. When our faces age, they not only lose tightness, they lose volume. So merely lifting and tightening the skin is not sufficient to rejuvenate your face. A fat graft uses fat from the abdominal area and places it in the mid-face to create a natural looking and youthful volume to the lifted face. These fat grafts, by the way, are already loaded with stem cells. I'm not sure there is any verifiable value to adding more. Other procedures I often recommend as an adjunct to a face lift are blepharoplasty, brow lift, chin liposuction and sometimes even a chin implant to provide more angulation of the jaw. These procedures done together create a “wow” factor that takes years off your face while still looking natural and “un-done.” I hope this helps.
