This is my "go-to" eyeliner! It's cruelty-free (a requirement for me), reasonably priced, well-pigmented, easy to apply (I have impaired vision, and the use of only one hand), and it wears tenaciously on my insanely oily skin. The tip is super-fine, which lends itself to creating a subtle "tightline...

'New Look' = Different Color
I went to get a fresh Eye Booster and saw the 'New Look' packaging. The eyeliner tube is identical to the one I had. Turns out it's a different shade/color. Left 'New' Deep Brown - grayish black in my estimation. Right 'Old' Actual Deep Brown. Sad that I'll have to give up my tried and true in searc...

Good eyeliner
Works well and doesn't irritate my eyes. Didn't notice any difference from eyelash serum.

This liner is pretty easy to use but I think the wet n wild breakup proof and kvd beauty are much easier. It didn't bleed into the inner corner, was very black, and didn't run or smudge. My issue is the bristles splayed out so I had to cut some off which was difficult, and I couldn't get as thin of a line as I'd prefer.
Best Basic Brown for Beginners
This is my holy grail, ride or die, whatever the best brown eyeliner I have used in a liquid formula. highly recommend
Favorite Brown Eyeliner
This is my favorite brown eyeliner that I have used, but it does have some downsides. First, the brush tip applicator is my all-time favorite and makes it super easy to get a crisp, thin line. Also, it is the best color of brown and does not look harsh on the eyes, especially for someone like me who is fair skinned with bleached hair. This liner does wear off fairly easily compared to black eyeliners I have used (every brown eyeliner I have tried has this problem), however, I find it lasts all day if it is set with brown eyeshadow. Another problem this eyeliner has is that the product builds up and dries on the tip after about a couple weeks of consistent use, but is easily fixed by wiping the dried product off the brush then it works like new again. My eyelids are dry so I dont know how it would work with oily eyelids. I have used the black color as well and it does have much better staying power than the brown does, but I love this brown and have bought it over and over again and used for many years.

ok product
it's an ok brown eyeliner but if you have oily lids I wouldn't recommend it. it fades through out the day. color is a nice brown that can be built if you let it dry between coats but I just wish it came in a water proof version.
