There are two distinct camps of lip color aficionados: Gloss gals and lipstick lovers. Me, my thin, perpetually dry lips force me to heart gloss. Maggie Gyllenhaal, she loves herself some lipstick.

We caught up with the young mom at Duracell "Power A Smile" Campaign kickoff in New York City, a charity program that spreads the love to kids who will be spending the holidays in hospitals. The Stella McCartney-clad MG dished on what powers her smile (note: No gloss. Ever.). "I like lipstick and it's kinda the only makeup I usually wear when I'm not working. I use Stila's Lipsticks on my cheeks as well as my lips, and I've recently been really into Julie Hewitt's Lipsticks." And her pearly whites? "I use a regular toothbrush, Tom of Maine Toothpaste and I go to the dentist."

So follow Maggie's tips for primping your smile, then take a few sec's to help out. Snap a pic of your grin and upload it here. Duracell will donate $1 to the Mattel Children's Hospital UCLA. Here are a few shots of Maggie with the kids to inspire you!
