This section is dedicated to questions that don’t easily fit into any other category but that concern facial plastic surgery. For hair restoration, see Dr. Lam’s Hair Transplant Forum. http://www.drsamlamhairforum.com/
The idea of stem cell is something that no one really knows about. I see nice textural changes after about a year or two following fat grafting (in many but not all) but things stabilize and then you have further aging (usually just slight). I think it is impossible for any honest clinician to comment on stem cell changes because we simply do not know nor do we even know that the effect that we are seeing is truly a "stem cell" change. best, sml
