"It's the blackest one I have tried — it lasts so long and doesn't crack. I do a cat-eye on myself daily, so I feel like I'm an expert in this area. I'm so happy I stumbled across this one!” — Kristin Gallegos, makeup artist to Riley Keough. NYC Liquid Eyeliner, $4.19, available at Walgreens.
The shape of this narrow, felt-tip marker gives you the best of both worlds: The fine point helps with precision work, and the wider edge allows you to go bolder. The carbon-black, glossy finish lasts a full day. $6.81 (amazon.com).
