What do you look for in a liquid eyeliner?
Super black? Affordable? Foolproof to use?
… How about sex-proof?
If that’s the case, step right this way because BOY do I have an unsmudgeable recommendation for you.

Beauty lovers are raving about the NYX Makeup Professional Epic Ink Liner for exactly that, according to Allure.
Reddit user okra_ shared her review on the makeupaddiction subreddit earlier this week, claiming "everyone who wears liquid liner NEEDS to invest in it immediately".
"I have been using it now for the last month or so and it is absolutely AMAZING and stays put through everything," she wrote.
"I know you're not supposed to keep your makeup on overnight (and I'm normally good about it) but I've fallen asleep multiple times drunkenly at a friend's place or had unexpected adult sleepovers (lol) and when I wake up the next day everyone (including me) is absolutely amazed at the fact that it still looks PERFECT every. single. time!!!"
