Kim Kardashian has gotten one. So, apparently, have other ladies in Miami.

A "blood facial" or "vampire facial" is a cosmetic procedure during which a doctor draws a couple vials of blood from your arm, centrifuges the blood to separate out the plasma and platelets from the red blood cells, and then adds the platelet-rich plasma back into your face. For extra absorption, the doctor pokes your face all over with a bunch of micro-needles before applying the plasma. Reminds me a little bit of making a Jell-O poke cake.

There's no evidence at all that this gory procedure works, and only the babiest starting evidence that injecting platelets into the skin works at all against the appearance of aging. But there probably is little harm, at least, to plasma injections because they deal with the patient's own body fluids, dermatologists say. The technologies dermatologists use for the facials are U.S. Food and Drug Administration approved for adding plasma to bone before orthopedic surgery... but not for wrinkle-busting.
