You HAVE To See What Hilary Duff Used To Look Like

Since she came on the scene 15 years ago, Hilary Duff has served as a walking Instafeed of top beauty trends. Throwback to her Lizzie McGuire era, and you'll recall the then-teen rocked teal eyeliner, extensions, and mad lip gloss — the onetime beauty essentials of ingenues everywhere. And now? The mother-of-one is right on target with a revolving door of rainbow-colored hair. (Duff says she gleans inspiration from Instagram, just like many of us.)

Despite her genius for landing on trend, all the time, Duff manages to dodge beauty victimhood by giving equal play to the classics, such as smoky eyes and dewy skin. But no matter how much she alternates between edgy and refined looks, the bright-eyed star always keeps it fresh.

This is the beauty evolution of Hilary Duff.
