Andrea Pomer­antz Lustig is known around the offices of Glam­our as the ​“Beau­ty Sleuth,” thanks to the pop­u­lar beau­ty col­umn and arti­cles she wrote for the mag­a­zine for the last decade. She is cher­ished by read­ers for her orig­i­nal tips, ideas, and solu­tions. Pri­or to Glam­our, she was edi­tor in chief at Sepho​ra​.com, and spent ten years as beau­ty and fit­ness direc­tor at Cos­mopoli­tan.
