BUY at Birchbox

You prep your skin before foundation and apply a base coat before nail polish, so it only makes sense to get your lashes ready for mascara too. A swipe of this primer strengthens and lengthens your fringe and helps prevent clumps. The black tinted formula blends in seamlessly underneath your mascara (read: no white streaks in sight), and even wears great alone on low-maintenance mornings. Lashes look longer, more defined, and dramatic for eyes that do all the talking.
