This mascara curls the lashes up and fixes the curve in place for beautiful results. Its proprietary Curve Memory formula uses a penetrating Curve Fixer ingredient*1 to lock in curl from the inside, with a Curve Coating ingredient*2 that gives the lashes a lifted yet flexible finish. Two types of fibers fuse with the lashes for added length. The Curve Up Brush grasps each individual lash, curling the lashes beautifully without any clumping. Waterproof type resistant to sweat, water and sebum. *1 Malic acid, sodium naphthalenesulfonate. *2 Microcrystalline wax.
