We caught up with top models Elettra Wiedemann - daughter of Isabella Rossellini - and the stunning Arlenis Sosa at the Lancome studio backstage at New York Fashion Week to get the inside scoop on all their beauty tips and tricks. The two faces of the Parisian makeup line revealed which products keep them gorgeous year-round, the beauty bag essentials they can't live without, and where else you can apply blush besides your cheeks!
