Kate Moss reveals her 'insane' beauty trick for perfect skin

​Today Kate Moss turns 43 - and the supermodel is looking better than ever!

So what is her secret for looking fresh-faced at 43?

In an interview with W magazine, Kate revealed that she dunks her entire face into a tub of ice to give her complexion a boost.

"It’s so good," she says.

While the beauty tip sounds like torture, the British model claims that the pain is worth it because it comes with an awesome benefit. "It definitely works, because all the blood comes to the surface," Moss explains.

If you're wondering where she learned the trick from, it wasn't from a family member or a friend. She picked up the trick from a classic movie. "I just watched Mommie Dearest! That’s what she does, isn’t it?" Remember the opening scene from the '80s film?

Moss was bold to test out the tip, but her curiosity proved to be worth it. "I first thought, 'That’s insane.’ Then I was like, ‘Hmmmm,’” Moss elaborates. "Those old school tricks work! With slices of cucumber and you just put your face in it and you definitely wake up."

At least this trick is free!
