Wandering the beauty aisles of a drugstore or Sephora can be equally exciting as it is intimidating. In a perfect world, every product we picked up during a shopping spree would be the one thing we can’t live without. Sadly, that’s not always the case (and the pile of lipsticks you swiped on only once and tossed to the bottom of your makeup bag serve as proof). It could take years of trial and error to figure out the beauty products that are worth your money. We asked the best pros in the biz—who test hundreds of products a year—for their ultimate, must-have beauty essentials. From international finds to drugstore buys, discover the new products you should seriously know about.
