As far as risks go, there aren't as many as you might think. In fact, Shamban explained that the only risk you really run is bruising at the time of the venipuncture. Aside from the discomfort of a blood draw and bruising from injection or microneedling, Zeichner says the vampire facial is "extremely safe, as it is your body's own blood being recycled."
If the procedure is carried out properly, the risks are low, except for people with blood-related medical issues, especially those which require blood-thinning medication. The microneedling causes temporary bleeding—hence the name "Vampire facial". Meanwhile, bruising, swelling, redness and pain may persist over the injection site, but these side effects usually disappear within a few days.
First, the injector (1) uses HA fillers to create a beautiful shape. (2) Then, the physician isolates growth factors from the patient’s blood. (3) When these growth factors enter the face (injected by the physician), then muti-potent stem cells become activated to grow new tissue. This new tissue includes new collagen, new fatty tissue (for smoothness), and new blood vessels (for a healthy glow).
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.
