Sclafani's injections are an off-label use of Selphyl, the Aesthetic Factors technology that separates plasma from the blood. Bruce Katz, another New York dermatologist who offers individual injections, uses a similar technology made by the Swiss company Regen Lab. Katz advertises "twilight plasma renewal treatment" on his website. His patients get about 20 injections at once in the face, neck and décolleté, he says.
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.
