What it is: Developed with plastic surgeons, this lash innovation is your peptide-infused black lash primer, eyeliner and mascara in one step.What it does: Unlike most other mascara brushes that leave the first 1/3 of your lash roots bare, the groundbreaking skinny wand starts coating your lashes at their actual roots to create a beautiful, lash-lengthening effect and lays down black pigment between each and every lash for instant tightline eyeliner definition and the look of a fuller lash line. How to use: Starting at the root of your lashes, hold the wand horizontally, then wiggle and sweep up and through your lashes from base to tips. It can be worn alone or under mascara. 0.12 oz.
