Other websites have a weekly Best Dressed pick, but Beauty Flash Blog has Skin Win, a list of the most glowing women we've seen recently.

This week's winner is Jessica Biel, who arrived at the Sundance Film Festival wearing a classic natural makeup look.  You can winterize your skin - and copy Biel's beauty style - with HydraQuench Tinted Moisturizer, which protects skin in extreme climate while boosting its color, too.  (And you thought multitasking was only for afternoons in the office!)  Add a moisturizing lip gloss like Instant Light Natural Lip Perfector, and you've not only given your mouth a sexy shine, you've also helped insulate it from harsh winds and chapping.  As for the rest of Biel's glow... well, we regret to inform you that Justin Timberlake is not sold on Clarins.com.

More looks we love:

*Freida Pinto with glowing cheeks and lips - something easy to accomplish with a quick swipe of Beauty Flash Balm.

*Dakota Fanning looking smartly sweet with candy pink lips.  (Protect your pout from winter winds with a moisturizing formula, like Rouge Prodige Lipstick in 111 Raspberry Sorbet.)

*Rooney Mara premiering her new movie Side Effects with a wash of brown eyeshadow - a nice alternative to the popular cat-eye, and super easy to do with a soft eye color, a few drops of water, and a small, clean makeup brush (look for one whose bristles are the size and shape of a Q-Tip).

*Jamie Lee Curtis wearing no makeup and a smile.  She likes Activia yogurt to get a flat stomach; we like Double Serum to get smooth, age-defying skin.  (It doesn't have fruit on the bottom of the container, but it does have 20 essential plant extracts, including super-fruits like bananas.)

*And Claire Courtin-Clarins, because she's wearing Joli Rouge lipstick in Clarins Red, which is kind of just super-adorable, n'est ce pas?  Also, if you're trying to emulate Claire's look, take note: Claire always uses Tonic Body Treatment Oil on her legs, and it's especially important in winter, when they can lose moisture more quickly.
