Your surgeon draws blood from your arm (not your neck, as many a movie vampire has been known to do) and spins it to separate out the plasma, which contains platelets. These are the proteins and growth factors that may stimulate collagen production and thereby promote skin regeneration and rejuvenation. There are several kits available to isolate these growth factors, and platelet-rich plasma (PRP). Once collected, the PRP is injected back into your face.
“Thanks to modern science, we now know that platelets contain various factors that stimulate the production of collagen, elastic fibers and new blood vessels,” says Mandeville. “Microneedling causes direct trauma to the skin. As a result, the body rushes to repair the wounds, sending platelets and cells to the rescue. As platelets play a significant role in terms of growth factors, it seems particularly appealing to inject the plasma back into the skin through the punctured holes to really speed up the healing of the tissues.”
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.
