Reviewers Cannot Stop Raving About Fiber Mascara for Serious Length

As most mascaras coat the lashes to make them appear longer and thicker, fiber mascaras go a step further by infusing tiny sticky fibers in their formula to extend and plump up lashes even more. The fibers, usually made of rayon, nylon, or even silk, enhance the fullness of lashes to give that glamorous false eyelash effect without the hassle of applying false eyelashes or getting lash extensions or a lash lift. Thus, fiber mascaras have grown in popularity but choosing one that offers that doe-eyed look can be difficult.

That's why here at the Good Housekeeping Institute Beauty Lab we have sorted through hundreds of lash-enhancing formulas over the years to find the best mascaras, including top-performing waterproof mascaras, hypoallergenic mascaras, and drugstore mascaras. We send the products out to consumer testers across the country to evaluate how mascaras perform at lengthening and volumizing lashes, and whether they flake, clump, or irritate eyes. In the Lab, our Beauty Lab pros test any waterproofness claims and use Visa images before and after application, which are later compared and rated on each mascara’s ability not to smudge, run or flake when exposed to water. Finally, after all the data is collected, we score all the testing to make our picks.

While we didn’t get to Lab test every last fiber mascara on this list, below are our top picks based on Lab tests, editor and chemist favorites or those that are highly rated and reviewed. Some of these mascaras have fibers in their formulations, and others feature a two-step process where teeny-tiny threads are applied to mascara-coated eyelashes. Here are the best fiber mascaras:
