The one thing in my makeup bag that I can’t quite live without, besides mascara, is liquid eyeliner. Even though I have mastered that steady line after years of practice, the right tool makes all the difference. And after trying what seems like hundreds of versions, I’m so excited to have finally found a nearly perfect one: Eyeko’s Skinny Liquid Eyeliner. I love how easy it is to apply and that it’s highly pigmented and practically smudge proof. Is there a liquid eyeliner that you swear by? Do tell!
