Best Bet: Clinique Bottom-Lash Mascara

Though most women wear mascara on a daily basis, bottom lashes are often left bare to avoid a clumpy, overdone look. Clinique’s new bottom-lash mascara is designed specifically to highlight fine lower lashes. The mini brush gives you added length and definition, making eyes pop without liner. We were dubious about smudging over the course of the day, but the slick formula is waterproof to cold water and flake-resistant (so you won’t have raccoon eyes by mid-afternoon).

Clinique Bottom Lash Mascara, $10 at Sephora or online.
