Kevyn Aucoin Volume Mascara
Waterproof mascara is undeniably enduring, often resisting even your eye-makeup remover. This brilliant formula is impervious to heat and humidity but rinses away with warm water and light rubbing when you're ready to be bare-faced. Makeup artist Troy Surratt also loves the skinny wand, which lets you get close the lash line to maximize the eye-opening effect.
