The freezing January weather at the Sundance Film Festival is harsh, but there's no better place to find cold weather beauty tips. Check out these smart tricks for blizzard-proof hair and skin, courtesy of the makeup artists and stylists who kept Kate Bosworth  and Elizabeth Olsen looking flawless during the fest.
Bright Eyes and Clear Skin
When it's dry and cold outside, you can't hide blemishes and dark eye circles with tons of concealer because your face will look flaky and cracked. To help de-puff actress Andrea Risborough's under eyes, makeup artist Nick Barose applied a Talika Eye Decompress  ($30) for 10 minutes. For an extra boost, Nick recommends putting it in the fridge so it's a little cold.
He hid blemishes with Guerlain Precious Light Rejuvenating Illuminator  ($48), a liquid formula concealer that isn't too thick and has light-reflective particles that enable him to use less product.
Sleek, Smooth Hair
Winter can dry everything out, hair included. For Elizabeth Olsen's smooth tresses, hairstylist David Stanwell liberally applied Leonor Greyl Spray Structure Naturelle  ($38) all over her roots for volume and body. After blowdrying her hair in sections using a large round brush, he finished the blowout with Leonor Greyl Laque Souple  ($36), a light spray that reduces flyways and maintains the bounce and body of the style.
A Glowing Complexion
Moisturizing is the key to plumping up skin and prepping it for makeup. To keep Kate Bosworth  looking radiant, makeup artist Kelsey Deenihan applied a calming and replenishing moisturizer — Votre Vou Attentive Crème de Jour For Sensitive Skin  ($39). To create a rosy glow, she then used both a powder blush and cream tint. She contoured Kate's cheeks with Nars blush in Zen  ($27) as well, and applied Jouer cheek tint in Poppy  ($20).
Especially for those with fair complexions, cold weather can make skin look dull and colorless. To give Vera Farmiga a sunkissed glow, makeup artist Nick Barose says he "mixed Patyka Huile Absolue Face & Body Serum  ($70) with a liquid foundation to warm up her skin."
