Helena Christensen may be the original clean girl.

The supermodel is dedicated to an all-natural skin care routine that starts in the great outdoors.

“If I’m in nature, my beauty routine is right away going outside, getting some sun, jumping in the river, swimming,” Christensen told Page Six Style exclusively at a recent NYC event hosted by wellness brand Lyma.

“Being in nature makes me feel like I’m blooming, you know? That’s what makes my skin glow: getting sun, being in the elements.”

That’s not to say the 57-year-old fashion legend doesn’t love products, however.

“I will literally try as much as possible and hope that there is a magical combination in there,” she said.

“[But] my beauty routine does not consist of a lot of different steps. Splash some water on my face in the morning, a little bit of hydrating mist, oils, serums and some moisturizer. And makeup for me, during just a day in my life, would be a little bit of blush and a gloss on my lips. That’s about it.”

Having worked with some of the industry’s greatest glam squads, Christensen loves to “transform” in front of the camera.

“I love crazy makeup. I love wigs. Because you become a different person. And that helps so much when you do a photo shoot, because you can create your own little story,” she said. “It’s wonderful to disappear into that world.”

But when she’s off-duty, she told us, “always, always, always it’s been very natural.”

Christensen will occasionally wear a red lipstick (“because I love the color red, and I love a clean face with just a pop in the middle”), but that’s about it.

“I never use mascara, ever,” she told us, saying she “[doesn’t] want to bother” with scrubbing it off every evening. (It helps that she inherited naturally long, dark lashes from her Peruvian mother: “I’m lucky,” she admitted.)

As for the top beauty tip she’s picked up during her years of modeling? Using fingers to apply products rather than brushes, which helps “really pinpoint where you put it” and yields a more natural look.

“Glowing, moisturized, natural skin is absolutely my favorite,” she said.
