Verdict: We love how Eyeko's subtle shimmer helps brighten up your eyes without making it harder to remove at the end of the day. But we're not a fan of the twist-up design that makes it hard to control the amount of product you apply. It's as long-lasting and smudge-free as Helena Rubinstein's, although the latter excels with a brush that is hard and pointy, good for creating more refined cat-eye flicks. It also dries faster. Shu Uemura's handy pen offers smooth, solid lines in a single stroke for a natural finish, but it doesn't last as long, especially on oily skin.
