Chang begins the 90-minute procedure with a deep cleansing of the face and the application of numbing cream. During the numbing process, Chang draws blood from the patient’s arm and then places two vials of blood in a centrifuge for 10 minutes to isolate the PRP. Chang then removes the numbing cream from the patient’s face, applies some PRP to the face and then injects the plasma into the skin with a microneedling machine.
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.
