Tried with matte and dewy textured concealers (Inc creamy concealer and heavier concealers), primer and on top of eye shadow but this eyeliner is the worst I’ve ever used. I’ve been doing feline flick liner for years but this is difficult to apply, it’s thin when it goes on and isn’t a solid black because it doesn’t go on evenly. If you then gently go over the area again to build it it rubs off the original liner. It flakes off after a few hours and becomes less black throughout the day. Would not use again and would not recommend.

I've used every formula and brand under the sun. This is my absolute Holy Grail eyeliner, can't imagine what I would do if it ever got discontinued. Jet black colour on the first coat, not too liquid, not too dry. Just perfect. It stays put all day and doesn't bleed onto the eyeshadows underneath. Both eyes under thirty seconds is a first for me and I always - always - achieve the perfect wing, thanks to the precise felt tip. Also a first.

I am an avid eyeliner user and I've tried pretty much everything under the sun. This is just great, can't imagine switching to something else. I got this as a present: I was resistant to buying it because of bad reviews on MUA. I have no clue what product these people are using, but it's certainly not this one. This is jet black on just one coat, with the most precise felt tip. It glides on, is not too liquid but doesn't dry too quickly. Doesn't snag on the skin (I'm in my late thirties, that's an actual thing) and stays put all day long. People seem to be complaining it's not waterproof. I don't understand how anyone could want more staying power than this eyeliner. It's honesty brilliant. Highly recommended.
