What It Is: Diorshow Overvolume, the mascara that successfully combines extreme volume and lash-by-lash definition, available in a waterproof version. What It Does: This waterproof mascara instantly delivers extreme volume boost while defining each lash for a fanned-out look. Its intense pigment coats lashes in a deep, no-transfer black shade that lasts up to 48 hours. Enriched with D-Panthenol and Blue Cornflower Extract, the formula helps protect, revitalize, strengthen and soothe lashes day after day, even under intense wear conditions. The Overvolume brush features an innovative combination of three distinct types of bristles. Petal-shaped bristles for intense volume and thorough, even coating. Fine bristles to capture even the shortest lashes. Precision tip bristles for impeccable definition. How to Use: Apply mascara to top lashes, coating them from root to tip. For extra volume, apply in a zig-zag motion. Use the tip of the brush for additional precision.
