First of all, a good clean mascara is hard to find. Using one often feels like you're gently highlighting your lashes with tinted coconut oil. But the Saie Mascara ($24) is so good, it might just be a cult favorite in the making. The rubbery brush really lets you define your lashes (it even has extra spikes at the end so you can get into the inner and outer corners), and the formula is layerable for tons of volume and length. It also won't smudge or flake, but it rinses off easily at the end of the day — the fact that it's clean is a bonus.
