I love this mascara, it's perfect for everyday use! It's not too dramatic and gives a subtle and natural look for long lashes without the clumping. It isn't water proof, but it does not smudge throughout the day and is easy to take off at the end of the day.

Not exactly waterproof but definitely water resistant, it’s lengthening and volumizing without that overly thick mascara look. Builds well with a few coats and holds a curl! My every day holy grail.

This is my go to everyday product. Ever since I tried it the first time I haven’t gone to another one since. It’s very long lasting and natural looking. My lashes look full and long when I apply this. And I’m aware I said it doesn’t clump and then put clumping as a con, what I meant by that is that while it doesn’t clump if you do put too much you start to get what I call “spider lashes”. No weird mascara chunks just your lashes sticking together, looking as if you have 3 big doll lashes on your eyes. Almost like you glued them together. I only found this out when testing out the build up but don’t worry it will take far too many coats for my liking for that to happen.

I purchased Lash Slick a little over two months ago, and instead of forming an immediate opinion like I usually do with a new beauty product, I waited. I wanted to see how often and under what circumstances I chose this mascara. Mascara is probably my favorite makeup item to purchase, and I've collected some quality examples from high-end companies as well as drugstores. I'm very fortunate to have long lashes, but they're thin and fine. I am always eager to try a new mascara that promises to make them look thicker and fuller, so I snapped up Glossier's version. Initially, I was fairly pleased with my results. I wasn't blown away by the dramatic transformation of my fantasies, but I chalked it up as a decent addition to my mascara arsenal. To my surprise, over the past two months, Lash Slick has been the mascara I reach for nearly every day. It's become my go-to for work, meet-ups with friends, errands, and anytime I want to look polished but not overdone. It gives me a natural, clean look that makes my lashes stand out for all the good reasons. Unlike my mega-blast-punch-you-in-the-face volumizing and curling formulas, Lash Slick is simple and quick to apply, and it doesn't end up transferring to my lids or brows. I don't need a separate lash comb to remove clumps, and it lasts all day without flaking. I wasn't sure why I would ever need a water-resistant mascara. I never wear waterproof mascara unless it's to a wedding or funeral because I dread removing it (and losing lashes in the process). It turns out a water-resistant formula was what I've really been looking for, I just didn't know it. This feature means that Glossier's mascara doesn't melt or smudge in 99 degree weather, and it doesn't run in the rain or if I shed a few tears when I laugh too hard or get a little emotional. Honestly, I had no idea how much I was crying in a given day... And Lash Slick is quicker and more painless to remove than most of my other mascaras. I love it, guys, and that's that.

CONS Agh. I really wanted to like this. I'm Korean and have thin, straight, short, sparse lashes that need to be curled before mascara in order to look like they exist. To date I have only found one formula that holds the curl instead of weighing my lashes back down to straight within seconds—Maybelline's Falsies. It's not the best formula out there (kind of flaky formula + clunky brush that holds too much product for a completely smudge-free, clump-free application), but I've tried so many "better" ones that just won't hold my curled lashes for some reason. The problem with this mascara (for me) is that, while the brush and formula REALLY deliver on their promises to lengthen and define, my lashes drooped before I finished a single coat, and, therefore, totally disappeared. The only way I was able to make it work was to curl again after it dried a little, but that creates clumps that weren't there beforehand. Maybe that can be prevented by waiting until they're completely dry before re-curling, but then this very "everyday" mascara wouldn't be so "everyday" for me anymore. PROS They did looked beautifully long and "wispy" and "enhanced" in the few seconds before they dropped. LOL. And the brush makes it really easy to apply to BOTH upper and lower lashes without smudging. CONCLUSIKN Idk. I like the lengthening/defining power of this mascara enough to give it one more shot with a longer wait time before recurling. But if that becomes too impractical, I'm returning. Turns out that, like most Glossier products, this looks the best on people who are already naturally blessed (this time, in the curly lash department). Side note: scary that Glossier has the power to make me mindlessly purchase this product, then justify kind of ridiculous extra steps just to keep using it even though it's flawed)
