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.
So, what is it and how does it work, exactly? Don't let the name fool you. In fact, "It's usually done in full light of day," says Beverly Hills-based dermatologist Ava Shamban. In all seriousness, the treatment is a "combination of a microdermabrasion, followed by the application of PRP (platelet-rich plasma)," says Shamban. "The PRP is derived from the serum portion of the blood, which contains platelets. The platelets contain high levels of growth factors, which, when applied to the skin, will stimulate cell turnover."
