TL/DR: very dark intense black, precise, stays on, can do multiple coats with no flaking or peeling, on the glossy side. A very good waterproof liner choice for us older ladies as it does not “skip” or crack on loose or lined lids.
I have to start by saying I've been wearing eyeliner- a lot of eyeliner- probably longer than quite a few of you reading this have been alive. I'm a make up artist, I worked at Nordstrom in cosmetics for years as a counter manager for a big name makeup company, and I've tried many, many different eyeliners over the years- cream, pencil, gel, liquid, cake, waterproof and non-waterproof. I decided to try this Revlon liner on a whim. The first thing I noticed when I opened it was the weird little “ball” on the end of the felt tip. I hadn't really noticed it as a feature when ordering it, and was worried I'd made a mistake by buying a gimmicky liner. I tested it on the back of my hand. Nice and deep pigmented black- good start. I could easily vary the line thickness by applying pressure to various degrees, so the little ball didn't make application difficult. I then tried it on my eyes. I have always worn a very bold 1960s eye, with eyeliner all around my eye, with a tapering cat-eye “tail” at the outer edge of the eye- sort of Cleopatra style. Although I am not young, I have taken good care of my skin, so I have very few wrinkles. But I do have a few shallow vertical lines at the corner of my eyes near my nose, and a lot of eyeliners will “skip” (or crack) here. This liner did NOT do that. It applied easily- dried fairly quickly- is VERY black, and a bit shiny, which I am fine with, as I set my liner with a light application of black eyeshadow. However if you prefer a super matte eyeliner, you might not be a fan of this liner's glossy finish. Personally, I liked it. So now to measure wear time. I wore this liner for six hours, at home, working on the computer. I made coffee and cooked, so was around hot humid air and did some Tai Chi, so I perspired a bit. Most liners that end up in the reject pile invariably fade or flake at the inner corner of the eye, near the tear ducts, or my cat-eye extension will fade a bit. This liner did not do this. There was a spot on one lid that was not as dark as I prefer, and I went over it with another coat of liner. No flaking- no peeling. I have purchased some very pricey liners in my day, and this one was outperforming all of them. It worked as well as my old reliable- MAC Fluidline- and it is much less expensive. You will for sure need waterproof eye makeup remover to get this liner off. Soak a cotton round with remover, and hold it against your eye for about ten seconds. Flip it over, and hold for another ten seconds. (Do not rub! That breaks down the fragile eye skin.) I didn't expect much from this liner, and I have a new favorite! Any of you who have loose or slightly wrinkled lids- give this liner a try. Very happy I found it!
