10 Outstanding Products That Changed the Beauty Business Forever

Any girl who grew up in the '00s is well acquainted (read: obsessed) with Lipglass. Glossy looks reigned supreme in the simpler days of Britney, Buffy, and Backstreet Boys. But not all gloss was created equal, a fact that MAC wisely capitalized on. Where other brands were just dumping more shimmer into their formulas to create that sheen, MAC product engineer Jenny Frankel (fun fact: she's also the cofounder of Nudestix) discovered an ingredient that created a vinyl finish without the need for excessive sparkles.

What followed was a revolution in gloss and a hero product that now comes in 57 shades and limited-edition launches that we all go gaga for. Forget matte — for us, it's all about that glassy gloss.
