Think of it as the little black dress for lashes. Unlike a traditional white lash primer this eyelash primer is tinted black so you can use it on its own. 3 ways to wear it. Tint: Colors and lifts bare lashes so they stay silky black throughout the day and even overnight. Amplify: As an eyelash primer its the optimal mascara base for volume and fullness. Set: Brush over mascara for a long-wearing smudge-proof finish. No well-dressed lashes should be without it.
