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."
