I received this eyeliner as a gift more than a year ago. At that time, my favorite eyeliner was the Kat Von D one and it soon became my second favorite! The Stila one is easy to apply, the black is really opaque. Even if it's a waterproof formula, it is easy to remove with micellar water.

Before I found Stila All Day Waterpoof Liner, no matter what I used, I always found that it wore off or smeared by the end of the day. This product is a LIFE SAVER! So many products claim to be waterproof, but this is the only eyeliner that truly lives up to its word. It dries quickly and won't smear, smudge or transfer. It's basically tattooed to your face until you use makeup remover!

The holy grail of all liners! I will never go back to any other liquid liner. I find this one to be the easiest to use and it no doubt stays on all day. It doesn't smudge or crease and on a rainy day it's waterproof. This is the liner I grab every time I do my makeup. I would recommend this one to anyone who has oily lids because you won't have to worry about it creasing or running. It has an easy to use felt tip that makes winged liner so easy to do.

BEST eyeliner I've ever used! I purchased the Kat Von d tattoo eyeliner to try something new and it doesn't even compare to the Stila eyeliner. Lasts all day and doesn't smudge !

The Stila Liquid eye liner is a great eye liner and I like the fact that it is waterproof. It goes on very easily since it is like a marker and lasts throughout the day. The black is nice and dark so it adds drama to your eyes. The only draw back is that it is a bit pricey but it is much better quality than lower priced liquid eyeliners.

Okay, so I have been a die hard eyeliner fan for years! No look is complete without the perfect winged eyeliner. I decided however to splurge on this product after seeing numerous good reviews! I can't even tell you how much this product impressed me in comparison to the drug store brand. It stayed on all night, through tears and lots of dancing! It was incredible! I fell asleep with a full face of makeup and woke up with it still perfectly in place. It is super easy to apply and makes a really nice bold, clean line! Definitely recommend to anyone wanting to take there liner up a notch.

I would buy this eyeliner over and over again! I've deviated only to come back to it. I love the slim pen size and also the felt tip brush. It's just the right thickness and length to tightline and create a cat eye wing. But what I love most is how long lasting it is. I wouldn't say it's absolutely waterproof (so far, have not found one that is) but it is the longest lasting and it also does not smudge at all, even during the summer heat.

The black is also a true black. I would definitely purchase this again (and already have!)

I really like this eyeliner. I used to use the Kat von d but it would dry out so quickly so I made the switch to Stila and boy do I live it. The only thing is I find it pretty expensive but it lasted me a full month when I use it everyday

Winged liner has been my look for years so I've been on the hunt for the best liner... this is the best!! Doesnt rub off in your crease..doesn't sweat off..doesn't flake off or fade. Seriously the best liquid liner there is!! I even need a heavy duty remover to take it off

This is probably the best liquid eyeliner out there. It's so easy to use and apply because of the applicator and it lasts forever! I would highly recommend this to any beginner who isn't too comfortable with liquid liners.
