Brand new never opened, Sephora sells it for $25 What it does: Inspired by the curves of a woman’s body, the hourglass-shaped brush was designed with extra stiff bristles to maximize the performance of this carbon black, collagen-fueled formula. One coat and lashes are full and defined. Two coats and lashes are even more luscious, curled, and dramatic. Three coats help you achieve the most intense, black, multidimensional lashes possible.
