Everyone knows Pinterest is a gold mine of recipes and DIYs, but lately we’ve been using it to aid our beauty sleuthing. Case in point: when an intriguing new product with thousands of repins shows up at the top of our personal feeds. Why has this product seen so much love? What is it about it that makes women want to pin it to their boards (which we all know is, like, the highest honor ever)? The answer is usually simple: because it’s good. Products that get repinned over and over are usually the most-loved in their class—and thus, we need to know what they are ASAP. With this mind, we asked our friends at Pinterest to share with us the one mascara that’s received over 10K repins in their vast network. Turns out it’s a true classic: Benefit’s They’re Real! Lengthening & Volumizing Mascara ($24).
