Bar Rafaeli underwent a so-called "vampire facial" - a rage with the rich and famous.
The supermodel shared a pic of herself during the procedure with her fans, Radar Online reported.
Kim Kardashian was one of the first celebs to go public with the vampire facial.
It involves drawing blood from the arm and separating it into platelet-rich plasma using a centrifuge. That's then combined with Restylane or Juvederm, and injected into the patient's face to stimulate collagen production, according to the New York Post.
It allegedly creates new skin and removes fine lines.
Rafaeli had the gory beauty treatment before debuting as a mentor on The X Factor in her native Israel.
