Female celebrities have tons of pressure to always stay beautiful and camera ready, and Bar Refaeli has gone to extreme lengths to ensure her looks are long lasting. The 28-yeaer-old beauty treated herself to a gold facial this week, a procedure that involves one’s face being covered in 24-carat liquid.

The high-end facial is said to give the skin a radiant lustre, and the gold is said to retain moisture in the skin, increase flexibility and smoothness, slow down collagen depletion and prevent sagging skin. Gold facials are also believed to prevent premature aging. But do they actually work, and are they worth the costly price? Dr. Jeannette Graf, a dermatologist in Great Neck, N.Y, told the New York Times that “there are absolutely no scientific studies that show that gold has any effect in firming or revitalizing the skin, nor that it reduces wrinkles or gives skin a plumped, golden glow.”

But there is no doubt that celebrities are willing to try strange products if they will keep them looking youthful and attractive. In January, for example, the Israeli fashion model got a vampire facial, for a whopping $1,500. Kim Kardashian also got the bizarre treatment, and made headlines after trying the blood facial on her reality show.

The treatment, which is marketed as “vampire facelifts,” entails blood being drawn from your arm, then spun in a centrifuge to separate the platelets, or small blood components. It is purported to give skin a younger-looking appearance.

Kardashian tweeted a picture of the result, which looked like a scene out of a scary movie. It's unlikely Kardashian will repeat the unique beauty regime, as she said on the episode, “Owww. Oh my God. I will never get a facelift if it feels like that.” Refaeli’s gold facial certainly looked more aesthetically pleasing, and pain free.
