A <a rel="noreferrer noopener" target="_blank" href="https://wwd.com/shop/shop-beauty/best-waterproof-eyeliners-1236149262/">waterproof eyeliner</a> may sound unforgiving — particularly for those who haven't quite aced the perfect cat-eye flick. Kosas' Soulgazer Gel Eyeliner, on the other hand, is impressively easy to apply. The pencil is thinner than your favorite lip liner and has a buttery-smooth glide, which makes fine-lining your lashes a breeze. Because it offers about 30 seconds of playtime before it sets, you can quickly smudge it for a smokey look or drag the outer corner of your liner up and out towards your brows for a soft flick. An included smudging tool and sharpener allow you to do just that without extra tools or cotton swabs for clean up. <br><br><strong>Price upon publish date of this article:</strong> $24
