It was Jovovich's early work with Herb Ritts, Richard Avedon and Peter Lindbergh that led to her success in advertising, bringing the young model contracts and covers for both "Vogue" and "Cosmopolitan". Since then, she has been featured on more than 100 magazine covers, including all the major fashion magazines in the US. She has been part of campaigns for Banana Republic, Christian Dior, Damiani, Donna Karan, Gap, Versace, Calvin Klein, DKNY, Coach, Giorgio Armani, H&M, and Revlon. Since 1998, Jovovich has been an "international spokesmodel" for L'Oréal cosmetics. She was referred to in a minor cameo in Bret Easton Ellis' novel "Glamorama", a satire of society's obsession with celebrities and beauty.
