Your surgeon draws blood from your arm (not your neck, as many a movie vampire has been known to do) and spins it to separate out the plasma, which contains platelets. These are the proteins and growth factors that may stimulate collagen production and thereby promote skin regeneration and rejuvenation. There are several kits available to isolate these growth factors, and platelet-rich plasma (PRP). Once collected, the PRP is injected back into your face.
You've probably seen the photos on Instagram: A celebrity or influencer's face covered with blood splatter. No, it's not Halloween makeup, it's actually one of the latest treatment trends in skin care, also known as a "vampire facial." Celebrities, including Kim Kardashian West and Bar Refaeli, are fans of the facial, which might look quite scary, but boasts big-time results.
