As someone who wears liquid eyeliner pretty much every day, it's really important that I use an affordable, very black, and very matte liner that is not prone to creasing. I had been a loyal buyer of the Wet n Wild Megaliner Liquid Liner for 3-4 years, but my last three have been...off. I only assume they reformulated them, because those three were far less black then they used to be, the product in the tube dried up more quickly, and they creased more than they used to. Since I love NYX, I gave the Matte Liquid Eyeliner a try. I briefly considered the NYX Epic Ink since I'd heard rave reviews, but decided it against it because I don't normally like liquid liners that come in pens without a jar of liner that it dips into.
The Matte Liquid liner comes in a very skinny tube that is completely straight up and down compared to other liners like my old favorite and the Revlon Colorstay. This gives the illusion of having more actual product. The brush handle is quite long and took some getting used to; it is longer than most liner handles I've dealt with, and this can make getting a very thin line somewhat trickier, but is great for getting a flick or cat eye at the end, I've noticed. The brush tip is soft and flexible, with no fraying since I've gotten it. It absorbs a good amount of product and the product does not clump on the bristles like I've noticed with others.
The product is VERY black! This is important for me in a liquid liner. It is a pleasing inky black. I would recommend another color, however, if you do not like dramatically black liners. It does dry down pretty quickly compared to most liquid eyeliners, and dries down to a very matte finish. Although it's not waterproof, it does not go anywhere. It does not crease on my very oily lids, which is great! However, this does make it harder to correct mistakes during application. Typically a Q-tip soaked in micellar water would suffice for my past eyeliner mistakes, but this one takes more (like a makeup wipe) to remove. I would say with this it's important to focus more on precision during application, which isn't too hard anyway. Removing it with the rest of the makeup is not bad though.
I am very happy with this because it gives me very dark and matte eyeliner. I usually do pretty thick liner, normally winged, and this makes it easy to do so. It is slightly hard to do a very thin line but it is definitely possible.
