What it is: A mascara with an innovative oblique brush that curls and defines lashes. What it does: Diorshow Iconic Mascara is the latest in Dior's dazzling range of bestselling mascaras. Created backstage for fashion shows and celebrity red carpet events, the Iconic mascara features an oblique cut brush that gives an extra lash-curling effect. With its long, skinny teeth, the plastic comb brush allows you to precisely coat each lash one-by-one, creating a long, separated fan of lashes that usually takes the skill of a makeup artist. The extra-hold formula provides a 24 hour-curl with 100% smudge-proof results. What else you need to know: Inspired by the tailoring technique of cutting fabric on the bias to create maximum curve, the Iconic brush features soft silicone bristles that spiral around the stem to lift, curl, and separate every lash.
