Beauty Secrets From the Most Powerful Women on the Runway

The role model: Hilary Phelps, founder and creative director of Genuine Joy, a lifestyle site that empowers women.

Deskside beauty must have: As a self-employed lady, Phelps works from home. But the one thing you'll always find next to her desktop is a great big glass of lemon water.

Everyday makeup essential: Phelps's philosophy is to keep things simple with both hair and makeup. For meetings, she applies a tinted moisturizer, a little bit of blush, and a nude lip gloss.

Best advice (ever): "Don't give up. Don't quit before the miracle. Right when it seems frustrating and you want to throw in the towel is right before great things happen."
