Vampire Facials. No not a superstitious relic from the dark ages or drawn from the imagination of a die hard Twilight fan, this is actually a real and apparently effective treatment happening in cosmetic clinics all over the world. Not your average facial it does need to be administered by a qualified practitioner (no a guy in a cloak with plastic fangs doesn’t count) as blood is drawn from your arm, spun out in a machine to separate the platelets and then injected into your face in the hopes of stimulating cell production. Many say it works but if you are squeamish I don’t suggest this is the one for you, it’s bloody hardcore.
Elizabeth Báthory has been doing it for centuries! As beautifully and gruesomely illustrated in a tribute scene in Hostel 2 (will not link images as they’re not for the faint-hearted!)
