Mascara is an essential part of our everyday makeup routine, and the formulas we keep in our collection are wide-ranging, from the lengthening and thickening to the vividly colored. And because the fat wands and volumizing formulas that fluff up our top lashes can be a little unwieldy, we even have defining formulas that are perfect for the bottom lashes. Below, we’re sharing our favorite mascaras for bottom lashes that deliver flake-free, clump-free results.The Best Bottom Lash MascarasL’Oréal Paris Telescopic Lift Washable MascaraThe newest iteration in the L’Oréal Paris Telescopic line, this TikTok-famous mascara gives lashes an instant floaty, lifted effect. The double-hook bristles grip every lash for even application and length, and the formula stays put for up to 36 hours.  Lancôme Le 8 Hypnôse MascaraThe serum-infused volumizing mascara promotes strong lashes inside and out. This formula will give you plush, pigmented, clump-free bottom lashes with just one swipe. Maybelline New York Lash Sensational Sky High MascaraThis flake-free, smudge-proof mascara has a flexible rubber wand to grip even the tiniest bottom lashes at the outer corners. It contains bamboo extract to help provide dramatic volume and length. It also comes in a waterproof version if you want extra staying powder. L’Oréal Paris Telescopic Original Lengthening MascaraOne of the most important factors to look for in a bottom lash mascara is a slim wand, like this one.
