Vampiric Beauty Kim Kardashian shows off the effects of a "vampire facial" or "blood facial."
The idea behind blood facials is that they infuse the skin with platelets, which contain growth factors, which in turn are known to be helpful in wound healing. Practitioners of related injections say the growth factors may stimulate new collagen growth in the face. Collagen is the protein in skin that keeps young'uns' cheeks firm and taut.
