My all-time favorite black liquid eye liner is from Stila. Stila’s Stay Proof Waterproof Liquid Eye Liner applies extremely well with it’s easy to use thin, marker-like pen. This eye liner makes creating a winged liner look incredibly easy and doesn’t smudge or run. Overall, I love this product, but it’s a bit pricey at $20.
I found a very comparable “dupe” pictured belong with the Stila liner. Milani’s Eye Tech Extreme Liquid Eye Liner also serves as a great liner, especially for creating winged or dramatic looks. It also comes with a felt-tip point marker that doesn’t smudge or smear. It’s a very comparable product at a much lower price, only $7. I would say the only difference is that the Stila liner doesn’t dry out as fast, but each liner lasted me at least 6 months. Otherwise, I think the Milani product does just as well!
