Why You'll Love IT™ Developed with plastic surgeons, Tightline™ is your peptide-infused, game-changing black eyelash primer, eyeliner and mascara all in one product! Unlike most other regular mascara wands that do not cover the first 1/3 of your lash roots, this groundbreaking skinny mascara wand starts coating your lashes at their actual roots to achieve a beautiful, lash-lengthening effect. The innovative wand also lays down black pigments between each and every lash to give you an instant tightline eyeliner effect and the look of a fuller lash line. This unique mascara primer is infused with an ultra-conditioning formula that combines the nourishing benefits of hydrolyzed collagen, proteins, biotin, jojoba, saw palmetto, chamomile, aloe, açai, amino acids, and antioxidants to deliver revolutionary, lash-changing results!
