The 'proper' name for a vampire facial is Platelet Rich Plasma (PRP) Therapy.
It's essentially a regenerative therapy, which uses nothing but the patient's own blood.
Platelets are tiny blood cells which play a crucial part in helping the body stop bleeding - as well as repairing damaged blood vessels and cells.
You could think of them as little powerhouses, which release proteins for growth when they come in contact with the body's tissue.
In PRP, a needle is used to draw blood from the client's arm. The blood is then spun in a machine, to remove the platelets.
The plasma from the blood is extracted, and spattered on the client's face using tiny acupuncture-style needles to rejuvenate their face.
