I remember going into Sephora and asking about the best liquid eye liners; Stila's liquid eye liner was mentioned. It is waterproof and stays on all day. It is easy to apply onto your eyes, and doesn't smudge. I have not had a problem with this liquid eye liner. All my girlfriends who ask which liquid eye liner I use, also agrees that Stila makes one of the best ones. At around $19 for the one I bought at Sephora, it was worth it! (And the amount itself is quite a bit, so it will last awhile!).

This is overall a good liquid eyeliner. Once you put it on, it doesn't budge at all. This is great for tightlining you eyes. The only problem I have is that the eyeliner pen has a felt tip, which means that sometimes the product doesn't come out very easily.

I walked into Sephora one day with the intent to find a black liquid eye liner that would be easy to use and last longer than most other eye liners I've tried in the past. I don't remember what I had originally picked, but the product wasn't even in the box when I got to the cash and the cashier recommended the Stila All Day Waterproof Liquid Eye Liner instead - with high praise. She was right! This liquid eye liner goes on very smoothly and stays put through long and stressful days. I would recommend this product to everyone and plan to try it in different colours in the future for different effects!

I've tried a bunch of different eyeliners, but I find myself coming back to this one all the time. It's pretty easy to apply, and it really stays on you. I don't have problems with smudging, and I like that you can get a sharp look with this. Note, though, that the black color seems to work better than the rest. I've tried the dark blue and brown , but they work noticeably less than the black. It also lasts me a while!

I used a Stila Liquid Eyeliner in blue. I loved it so much, I'm thinking about going out and buying every color. The only thing about it is that it's really liquidy. You have to put on one layer, wait about 30 seconds and then apply another layer or its pretty messy. Otherwise, I love it. I LOVE the sparkly blue color I got.

Good product easy to use creates a smooth line without effort last all day without any smudging . What I like the best is it drys really fast!

Thanks AGAIN to ChickAdvisor for sending me this as a prize for review of the week!
I got this in "Moss", a really nice green shade. It brings out the green in my eyes and I also like how it works for both day and night without being too over the top.
Liquid eyeliners have always intimidated me a little bit, especially waterproof, because my hands just aren't that steady! But I had to experiment with this, and I'm glad I did. It wasn't as difficult to apply as I always remembered liquid liners to be.
The product goes on perfectly and it's easy to control how you want it to look. The tip is soft and easy to manage and the product stays where you apply it - no smudging and flakes and it is definitely waterproof.
I really like this liner and would purchase it / recommend it to others.
