Birchbox Breakdown

Long-lasting gel liners are kinda like unicorns, a beautiful notion of mythic proportions…that doesn’t really exist. That is, until we met this heroic eyeliner from CAILYN Cosmetics. The inky gel goes on smoothly like a traditional liquid liner and leaves behind a line of rich color like a high-impact eye pencil. It even comes with a built-in brush so you can get a bold eye even while on the go.

How to Use

Dip the tapered eyeliner brush into the gel formula, coating both sides of the brush with color. Wipe off any excess and begin by lining in the middle of the lash line, moving towards the outer corner of the eye. Next, apply the liner all the way to the inner corner of the eye.

Love this product

I was using another we'll know gel liner, However I think this one works MUCH better. :). I wish the brown was a bit lighter though.

Pleasantly surprised

Applies flawlessly. Liquid can go on too thick, smudge or flake. Pencil can be hard to remove, and look too penciled. Unnatural. This is the perfect balance.

Easy to apply
Purchased

I am pretty low maintenance when it comes to make up and don't know how to apply most things. BUT I wanted to try an eyeliner and after reading reviews decided to order Cailyn, THIS IS GREAT! It's so easy to apply and looks awesome!

I am now a believer

I was skeptical about this, cause I'm a super newb and the brush scared me! But it was all for naught - it goes on so easy and so solid. Very smooth application, stays on all day. I'll most likely buy more colors :)

Not what I was expetcing

Sorry, wanted to love this... but It is not easy to apply in the way I was looking for... I wanted a dark, thin eyeliner that went on solid, more like a liquid or cream. This is a thicker brush with a more eye shadow consistency.

One of my faves

I have this gel liner in both Chocolate Mousse and Iron and use one or the other almost every day. They are both really dark shades, iron is pretty much black. I love the clever applicator brush hidden in the cap, it gives great coverage and is easy to clean. The liner stays on all day. Love!!

love this eyeliner
Purchased

This eyeliner is AMAZING!!! It is so easy to apply and allows you to get really creative with your wings. I don't know how I survived with the pencil eyeliners for so many years, I'll never go back. The brush applicator is super easy to clean and can applies a nice thin or thick line on my eyelids.

Great eyeliner!

I absolutely love this eyeliner! The brush is perfectly-shaped to create a beautiful cat eye that stays on forever and doesn't smudge. The consistency of the gel is not so thick that it doesn't glide easily and it's not too creamy so that iyour hand slips. And how convenient is that the brush is the top so hat you can bring it with you! I used the dark purple color every day for over 5 months until it ran out and I was so sad when they stopped selling it! I might have to purchase the dark blue because it was the longest lasting and most easy to use eyeliner I ever had. Highly recommend.

Great eyeliner
SampledPurchased

I love this eyeliner, probably one of the best I've tried other than Chanel's eyeliner. Love wearing the black eyeliner at night or for events because it stays on ALL NIGHT. I bought another color, black shimmer, that I don't think they're selling anymore? But I wear that for an everyday look- a little more subtle than the black. I've found that after you apply it to your eyes, it's best to wipe the brush off so it doesn't get clumpy or hard. Other than that, I'm on my 3rd one so far. They also last a really long time!
