Even when she was a child, 21-year-old Mischa Barton’s beauty was undeniable. Modeling for Calvin Klein at age 11, she kicked off a career as an advertiser’s darling, appearing in campaigns for Neutrogena, Bebe and Keds. From 2003 to 2006, she further secured her pop-culture presence as TV’s drama teen Marissa Cooper on The O.C. And now she’s taking on the big screen (look out for Virgin Territory with Hayden Christensen). So what’s the secret to her allure? According to her makeup artist, Nick Barose, it’s her understated glamour. “She doesn’t like a typical Hollywood look with fake lashes and bronzer.” Instead, she keeps it simple "with a small element of fun,” like black polish or layered shadows on the eyes and nude lips. “In 50 years, she will still look timeless,” says Barose. Especially if the first decade is any indication.
