Hayden Panettiere and Connie Britton went head-to-head as dueling Country music stars last night on the season premiere of Nashville—and they looked stunning doing it. We caught up with the show's makeup artist, Erin Koplow, and got the inside scoop on her favorite products and how she gives the actors their Southern glow. "One product that I truly can't live without is Neutrogena's Healthy Skin Custom Glow Blush and Bronzer," Koplow told InStyle.com in an exclusive interview. "It gives them a healthy, sun-kissed glow." For a nice flush into the fall, use a large round-headed brush and sweep the bronzer upward on those areas that the sun would naturally hit—forehead, tip of the nose, and apples of the cheeks. To get the stars' bold, stage-ready eyes, Koplow used a liquid liner on lids and applied a generous coat of Neutrogena's Healthy Volume Mascara in Carbon Black. "This mascara is a must!" she told us. "It gives them full, lush lashes and provides the perfect eye framing." After using an eyelash curler, apply two coats of the mascara starting at the root of lashes, pulling upward. Pick up the bronzer for $9 and the mascara for $6 at neutrogena.com.
