I have really wrinkly, heavy-lidded eyes (always have; you should see my baby pictures!) And I always admired the look of liquid liner but never could figure out a way to make it work for me. It was too hard to apply without messing up and it would ooze into my wrinkles. It didn't help that I have a hand tremor, so there's a lot of trial and error involved in applying makeup.

Stila's liquid liner has changed all that, though! I love it. The felt tip makes it easy to apply, and if I mess up I can just wipe it away with a q-tip- but it stays put until I WANT it to wipe off! It leaves a clean line with pure color- no blotchiness, and it doesn't smudge or fade.

I can't praise it enough. I want one in every color. :)

So far... this is by far the best eyeliner I've tried. My only con to this product is that it's so shiny. I'd prefer a more matte look to eyeliner.
I can look past the shiny-ness for the stay, non-smudginess of it though.

I have always hated liquid eye liner because it's so hard to make the lines even! The tip on this liner makes it so easy. It stays on and is the perfect black--not too intense but not too faint either. Perfect for people like me who are not used to liquid eye liner.

I use this when I'm in a hurry and have no time to use my gel liner. I still prefer gel but this is so fast! 5 seconds each eye.

Seriously is the best. It doesn't melt off in the heat. It's a fine tip pen, which is the easiest of liquid eyeliners (at least for me) to apply. When it comes to liquid eyeliner, I will never buy another brand, but Stila.

No matter what new liquid liner I try, I always go back to the Stila liquid eye liner. It's super black, applies on easily with the sponge brush tip, and you can easily create thick and thin lines.

LOVE this eye liner. Literally stayed on until the next day and looked exactly like it did when I first put it on. The color is perfect and the pen makes it very easy to use and put on a straight line.

I love this eye liner. I can get surgical precision on my cat eyes while sitting in the passenger seat of a car. I love the way you can control the thickness of your line and that it is mess free. Love it.

This eye liner works great - it stays on all day and doesn't smudge or run. It's easy to put on. I bought the brown and it's a great color!

So, i am a long time liquid liner user. For years i used MAC, but since i do not live close to a MAC store I tried out the Stila one. I really like it, the black is nice and dark, it is easy to go on and do my cat eyes. My only negative is that unless you use a primer underneath it will fade a bit during the day.. especially the fine points of my wings, they seem to blur if there is no primer. Otherwise, i plan to keep buying!
