The deal is this: Blood is drawn, usually from the client’s arm, then placed in a centrifuge in order to separate the plasma and the platelets from red blood cells. The resulting liquid is called platelet-rich plasma, or PRP. The plasma contains protein and other nutrients that are supposed to help stimulate skin cell growth and collagen. Then that material is either applied topically or injected into the face using microneedling techniques, which essentially involves puncturing the skin many times with super-tiny needles. The theory is that the holes help the growth factors and other nutrients get into deeper layers of the skin.
In laymen's terms: It's a facial that essentially uses, "your own blood to help promote the healthy activity of your skin cells," says Joshua Zeichner, the director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City. Our blood is comprised of red blood cells and serum, which contain our white blood cells and platelets.
