CAILYN Cosmetics Gel Eyeliner

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.

I have been in search of the best gel liner for a long time. I needed one that didn't smudge, and also stayed on without flaking by the end of the day. I am extremely happy with this product & the same size is huge!

That packaging!
Sampled

The gel eyeliner itself is fine, and it's always cool to receive a tool (the brush) in addition to the makeup. I love the brush, and I think the eyeliner goes on pretty well though it doesn't really stand out to me from other gel eyeliners. My biggest issue was the packaging - the squeak of the plastic on plastic is like nails on a chalkboard, and it's so bulky that it's definitely not something portable.

The best eyeliner

I love this product! I was never a dedicated eyeliner wearer until I found CAILYN gel eyeliner. It spreads easily, does not smudge, and stays put all day! So excited to see Birchbox carry it now!

Goes on smooth for the long-haul

Super creamy and smooth, easy to use and forgiving unlike liquid, it lasted until I was read to take it off. Love the brush in the lid. Didn't love the iron shade, but I'd love to try another hue.

Love this eyeliner!

I received the Cailyn Gel liner in Iron in another beauty bag a few months ago, and I absolutely love it. Unfortunately, the Cailyn liner I received in this month's Birchbox in black was dried out. :( The lid wasn't screwed on completely, and it was hard to the touch. Overall, I love Cailyn's products, and definitely recommend the liner.

Long lasting for sure

This is a great eyeliner. It last long. The brush that comes with it is to thick for me so I use my own eye pencil. It takes me a long time to go through an eyeliner and this sample was full size, so ill be using it a while. I will buy in a differant color next. They have many to choose from. Purple will be my next one I buy.

Survives Day At Pool

I thought the packaging was really neat, so I was excited to try how it works as soon as I saw it. I drew a small black line on my hand, which withstood a dozen hand washings during a shift at work -- then I was REALLY excited to try the next morning with my makeup. And this particular day was an ultimate test, a day at the pool. In and out of the water, being splashed by kids, rubbing water out of my eyes. And as I got ready for bed, it still looked just as it had when I had applied that morning. Never using a greasy, smudgy pencil again. The brush included was not as precise as I would like, causing my eye liner to be a smidge thicker than I prefer, but I will be trying with my own, thinner brush tomorrow. Would recommend.

Different, but I like it!
Sampled

The packaging was really fun, I like how the brush is inside of the lid. I got the black color in my box, but would be interested in trying the other colors, too. It goes on very easily with the brush and didn't seem to run/smear throughout the day.

Love this liner!
Sampled

I already own a pot of this stuff and I was thrilled to receive a full-size spare in this month's box! I am a little eyeliner-challenged because my eyelids are a weird texture and liner usually doesn't go on smoothly at all, but this stuff is a miracle. The brush is perfect, the product glides on smoothly, and it stays all day. I've even worn this stuff to the pool and the beach and it did not smudge or run at all. HIghly recommend!

Excellent!
Sampled

I think this may be my new favorite eyeliner. It combines the precision of liquid liner with the flexibility and softness of a pencil. I love that I can get a variety of different looks by changing the brush angle and amount of product. I got the black liner in my BBox, but I'm definitely going to buy the brown as well.
