Olya Banchik

Dentist and founder of Smiles for Survivors, a nonprofit dental foundation; age 34

Style icons:: Kate Middleton and the Mad Men cast.

What she’s wearing now: Ports 1961 sweater, Joe’s Jeans, Gucci shoes and belt, Dee Berkley bracelets and Proenza Schouler bag.

Although this Russian-born dentist says fashion is her passion, she also holds beauty a very close second. “I believe that beauty comes from the inside out, so I try to follow The Beauty Detox Solution by Kimberly Snyder,” Banchik says. By making changes to her overall diet, which includes eating minimal protein and starches, plus adding more fruits and veggies to her plate, “my skin looks better.” So what’s her best beauty advice? “Floss daily.”
