When I'm looking for new skin-care or makeup recommendations, I turn to my favorite beauty bloggers. Part of a beauty blogger's job is to test and review products before they hit the shelves. 47 hero items that they use and buy over and over again. Ahead, six beauty bloggers share their holy-grail products, and why they love them so much. Whether you're looking for a new all-purpose sunscreen, an eyelash curler, or an all-around eyebrow styler, there's a little something for everyone on this list.
