Bar Refaeli is bloody beautiful — literally.

The Israeli supermodel and actress shocked fans Saturday by posting on Instagram a photo of herself with blood smeared all over her face. The selfie was taken as she underwent a beauty treatment known as a vampire facial.

We first heard of this gruesome procedure when Kim Kardashian tweeted a photo of her blood-spattered face last March. The New York Daily News reported that the $1,500 procedure, trademarked as “The Vampire Facelift” by Alabama doctor Charles Runel, involves drawing the patient’s own blood from her arm, and separating it into platelet-rich plasma using a centrifuge. The plasma is combined with Restylane or Juvederm, and injected into the patient’s face to stimulate collagen production. This supposedly creates new skin and removes fine lines and acne scars.

According to the Daily News, Refaeli and Kardashian are far from alone in undergoing a vampire facelift. Cosmetic surgeons to the rich and famous in New York and Los Angeles are apparently doing the procedure on at least several patients per week.

Well before Refaeli, 27, posted the bloody facial pic, she posted another photo in August 2012 of her arm as she was getting a blood test. “Big girls don’t cry,” was the caption she gave the image of the butterfly needle in her arm and blood running down a tube. Perhaps she was practicing for the vampire facial, with looks none too comfortable.

The supermodel posted on yesterday’s Instagram photo that she had gone to “Dr. Paula” for a vampire treatment in preparation for her live appearance on the “X-Factor” televised musical talent contest, which she hosts.

The Channel 2 show has drawn a huge 1.1 million-strong audience since debuting in Israel in October.
