8 Best Waterproof Mascaras That Won’t Run, Smudge or Smear

This under-$6 pick is a cult classic for great reason. Our testers loved that the formula went on smoothly, added lots of volume and lengthened without flaking or smudging. They said this brush was the easiest to use, and the formula also snagged perfect scores for being non-irritating, even on sensitive eyes and skin. In the Lab, it earned a perfect score for not running even when doused with water, but the trade-off is that it can be tough to remove.

If clean beauty (or vegan and cruelty-free makeup) is a must for you, this “clean” version of the cult classic is all that and it got a perfect score in the Lab for not running when exposed to water. Consumer testers rated it best for volumizing and thickening lashes and it got second-highest scores for overall satisfaction and creating the desired look. “I like how easy it was to coat all of my lashes,” said one tester. “It made them look longer and fuller.” This formula is easy to remove, but the downside of that, as several testers noted, is flaking and smudging.
