Precision meets Innovation 😍😉
The Revlon Colorstay Lash Serum Plus Liner has quickly won me over, and here's why. First, let's talk about the basics: I'm not sure if this liner comes in other colors, but the blackest black shade is absolutely perfect for me. It's bold, rich, and exactly the kind of pigment I always look for in ...

One Product, Two Jobs—But Only One Shows Up to Work
[I received this product in exchange for my honest review] 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 b...

Great 😊
I usually don't get eye liners because they are really hard to use however the tip of this applicator was very helpful and manageable. Also was very easy to clean after a little mistake. I really like that the color is very pigmented.

Long lasting
Not sure how it works as a lash serum but love the liner. Goes on smooth, long lasting, and easy to apply. The applicator tip is really nice as well.
as a dancer, it stays on for DAYS
listen- i'm super ambitious so i do 5 different genres of dance, and just had a show recently. quick changes galore, with only 2-3 dances in between mine to change into the next costume (2-5 minutes) and this eyeliner didnt break a SWEAT when i was. in fact, it stayed on for days afterwards (i kept forgetting to remove and didnt have time), and i am so impressed. even in an 80+ degree humid theater with over 400+ people, it's so hard to smudge. the felt applicator is thicker than others, but i enjoyed that more than i thought i would because it felt much sturdier which helped with my confidence in putting it on. i have no idea about the lash serum part, i always wear cluster lashes but the eyeliner itself is AMAZING. 10/10 would buy again and again
Not for Oily eyelids
This isn't a bad product just not for me. The application was very smooth it but was patchy for it. Its really easy to take off with water or just rubbing it off. The pen is easy to hold and I love how it's pointy but it's just not for my Oily lids.

Amazing
[I received this product in exchange for my honest review] Works pretty well! Glides ride on, I might be switching to this over my nyx eyeliner after this! Definitely recommend 10/10 helps the lashes become very voluminous
