What it is: An award-winning mascara that has been a backstage cult favorite for 10 years. What it does: This mascara delivers perfectly plush, glam lashes with an innovative XXL brush for show-stopping volume. Its creamy, buildable, customizable formula allows you to achieve the same dramatic lash volume that can be seen on the Dior runway for a glamorous, false-lash effect. What else you need to know: This legendary brush was inspired by Dior makeup artists who would use plush toothbrushes to coat models' lashes backstage for volume that a regular mascara wand couldn't create-until now. It's also available in a waterproof formula.
