Platelet rich plasma skin rejuvenation has grown in popularity in recent years, sometimes being referred to as the vampire facial. Celebrities like Kourtney Kardashian swear by the procedure's anti aging effects. She has also received PRP therapy to help grow back a bald spot in her hair. "I love platelet-rich plasma [treatments]. They take your blood and spin it, and then take the plasma and microneedle it [into your face]. They call it the Vampire Facial" she said. "It's usually a day of downtime, but it's something I like to do as often as I can."
