Revlon ColorStay Lash Serum + Liner - Waterproof - 001 Blackest Black

[This review was collected as part of a promotion.] These eye liners are really nice and they go on my eyelid really well. The eyeliner is like a very sharp felt tip marker. It is a nice dark black. Also its cheap

[This review was collected as part of a promotion.] I normally don’t wear liquid mascara but I really like this product. Applied easily and is very light weight. There isn’t really a scent to it but I think it’s worth the money

[This review was collected as part of a promotion.] This liquid liner was easy to draw on. Not too expensive. Lovely scent. Cute packaging. I would totally recommend to a friend. I absolutely love the Revlon brand.

[This review was collected as part of a promotion.] I absolutely love the Revlon ColorStay Lash Serum + Liquid Liner! The brush tip glides on effortlessly, allowing me to create sharp, precise lines with ease. The rich black pigment stays put all day without smudging, even on my oily lids. An added bonus is the lash serum infused with Tahitian microalgae, which nourishes my lashes over time. It’s a fantastic 2-in-1 product that combines makeup and lash care seamlessly. Highly recommend!

[This review was collected as part of a promotion.] I am not so sure about the formula for the Revlon Colorstay Lash Serum + Liquid Liner. The packaging is nice I will say but after I apply the liner, it piles up which is weird.

[This review was collected as part of a promotion.] This is a nice liquid eyeliner that goes on smooth and easily for nice crisp lines. Lasts all day without flaking off and has a nice brush tip applicator.

[This review was collected as part of a promotion.] Eh it’s not really different from any other liner. It wears out quite fast too. I like that it has a lash serum as a bonus but I haven’t seen any results if I’m being honest.

[This review was collected as part of a promotion.] This eyeliner is solid. It works well as a felt tip eyeliner. I haven’t experienced the eyelash effects yet, but i like that it is a 2 in 1 eyeliner.

[This review was collected as part of a promotion.] Great liner, I get watery in the corner of my eyes and I havent found many liners that don't have issues with that and this one did better than others! There's no scent, the application is always easy for me with a felt tip brush so I appreciate that, goes on super smooth not too liquidy. Easy to use

[This review was collected as part of a promotion.] I don’t use liquid eyeliner, but this one is pretty good. The application tip is easy to apply and there is a perfect amount of liquid that comes out. No scent.

[This review was collected as part of a promotion.] The Revlon ColorStay Lash Serum + Liner Liquid Liner had me intrigued—liner and lash serum? We love a multitasker. Unfortunately, this one’s a little more “concept over execution.” As a liquid liner: It’s… fine. The pigment is decent—true black, semi-matte—but not as rich or intense as you’d expect from the ColorStay line. The tip gives some precision, but it can skip or feather if you’re not careful. Dries fairly quick, but not waterproof enough to survive a misty day or allergy season tears. Longevity is mid at best. Like, don’t touch your eye unless you’re ready to reapply. As a lash serum: Let’s be real—if there are any lash benefits happening, they’re extremely subtle. You’d have to use it consistently over weeks and squint to see results. It’s not irritating, which is a win, but it also doesn’t deliver the kind of growth or strength you’d expect from something marketed as a serum. It’s giving wishful thinking in a cute bottle. Packaging: It’s sleek, travel-friendly, and looks luxe for the price point. No complaints there. The brush tip could be better, but it’s workable. Bottom line: It’s trying to be a two-in-one hero, but really ends up being a so-so liner with a side of lash placebo. If you want bold, stay-put liner or actual lash growth—you’ll probably want separate products. Cute idea, just not quite pulling it off.

[This review was collected as part of a promotion.] Amazing eyeliner! This eyeliner is very precise and the color is unbeatable. As you can see next to my black tattoo the eyeliner is even darker!! Thats insane! I love the product and can’t wait to use it for date night!

[This review was collected as part of a promotion.] Very pigmented! One swipe and you are covered - the packaging is great and my brush has yet to dry out like many others I’ve tried. Also, comes right off with a gentle eye cleanser!

[This review was collected as part of a promotion.] Making a long lasting liquid eyeliner that’s ALSO A SERUM is genius. I don’t know how this hasn’t always been a thing?!? Easy glide, black as my soul, stays put, and also makes me feel good about what I’m putting on my eyes. Can’t beat it.

[This review was collected as part of a promotion.] This was perfect timing since I needed a new eyeliner anyway. I was very impressed with it. It’s a perfect dark black color and it glides beautifully on my eye. Will continue to use

[This review was collected as part of a promotion.] Very nice dark liquid liner , love the application tip as it makes the lining easier .its not waterproof but definitely doesn’t smudge.overall I like it

[This review was collected as part of a promotion.] Great budget eyeliner. Glides on beautifully, doesn’t smudge and looks great on my upper lash line (I did a small cat eye). Also love that this liner is a combo deal as it has lash serum. Can’t wait to see if the serum helps my lashes grow!

[This review was collected as part of a promotion.] This review was collected as part of a promotion.] Very pointed brush tip, making it easier to apply. This is an interesting product with the eyeliner having a serum in it to moisturizer your lashes when used on your eyelid and lower lash line.

[This review was collected as part of a promotion.] The Revlon colorstay lash serum and liner liquid liner is a good liner. It is not my go to but I keep it in my makeup kit as a good back up. It comes off easily with makeup remover.

[This review was collected as part of a promotion.] It was smooth, no sticky feeling when applying and easy to apply, and my eye didn't itching, which is new for me. I didn't have a tough time either.
