The L'Oreal Super Slim Liquid Eyeliner has garnered mixed feedback from guests, with many expressing disappointment over recent changes in its formula. While some appreciate its precision and ease of application, others report issues with dryness, smudging, and lack of pigmentation. Guests have noted that the eyeliner can dry out quickly and may not perform as well on oily eyelids. Despite these concerns, some still find it to be a reliable choice for creating fine lines and achieving a polished look.

Not impressed
It started out great on the eye lid. When I got to the bottom lash it wouldn’t work. I tried it on a tissue and had to press too hard to get the liquid to come down then it wouldn’t transfer to my lash line. Definitely a waste of money.

Hello! Thank you for sharing your feedback on our Infallible Super Slim Liquid Eyeliner. We are sorry to hear that the precision felt tip did not provide the smooth, consistent flow you expected for your lower lash line. To help activate the formula and ensure the ink reaches the tip, we recommend storing the liner tip-down and giving it a gentle shake before use. Ensure your eye area is clean and dry, free from any oils. We have shared your specific comments regarding the application with our product development team, and we hope you find your next favorite eye essential with L'Oréal Paris!

Avoid buying - dry, not smooth application
Tip was completely dry after opening it on the day I bought it. I tried turning it on its side and kind of using just the thick bottom part to at least cover just the upper edge of my eyelid, after giving up on creating a wing, but even that wasn't a smooth application. If you need a better recommendation I found that NYX's Epic Ink Liner lasted months where I didn't notice any dryness or lack of quality. It's much wetter and easier to apply

Hello Alex! We are very sorry to hear about your experience with the Infallible Super Slim Liner. Delivering a precise, fluid application is a priority for us, and it is disappointing to learn that the product did not meet our quality standards upon opening. To help revive a felt tip that may have settled during transit or storage, we suggest storing the liner tip-down for twenty-four hours to allow the formula to fully saturate the applicator. Additionally, gently wiping the tip with a damp tissue can sometimes remove any surface film that may be hindering the flow of the ink. We appreciate your feedback as it helps us maintain the high quality expected from our Infallible collection.

Worst eyeliner I've ever used
This is probably the worst eyeliner I’ve ever used. The tip was completely dried out from first use, so I could barely get any product on my eye. When I would try to fix it, it would smudge whatever product I did have on my eye, making it look even worse. It was so frustrating and such a waste of time to try and get the eyeliner to work, and a waste of $9.

1 use wonder
I love this product! It didn't smear and cause black circles under my eyes. But it runs out after 1 use. I bought several tuning maybe it was just a bad batch. Everyone is bought did the same. The first time I used it about a year ago, it lasted longer then 1 use.

My favorite eyeliner
The BEST eyeliner! It makes eyeliner lines so crisp and sharp. Lasts a long time too! the pointed edge makes for easiest wing application. Lasts all day but is not difficult to remove with any face wash.

Dry Applicator
I have been using this eyeliner for years always got compliments and just recently, The last month or two. Each one I’ve purchased seems to dry out right after using once. I’ve purchased from several different stores hoping it. Was just a bad batch and still dry applicator. What’s going on??

Looks good initially but smears!
I like the ink pen eye liner, however it smears and smudges! It doesn't even stay on in one place for long. I will not buy this again.

Smells bad
It just smells real bad. I bought it a couple of months ago and packaging and everything else is superb. But the eye liner smells chemically bad.

Something changed!
Flowerchild52 got it right! The "new" super slim is so dry it will not even line one eye. I, too, bought several thinking I must have gotten old stock. I used / loved this product for years - please bring it back!!!

Dries Out Quickly
For about the first week, this was a good eyeliner. After that it started to dry out which also led to the stick breaking. Now it's basically no color pay off and scratches the eyelid. I used less than half the product before giving up and throwing it out.

What happened to my Loreal Super Slim eyeliner?
I have loved Loreal Super Slim eyeliner for years and years. But I am sad to have to give my all time favorite eyeliner a bad review. My favorite eyeliner has changed in the last six months. I can not even line one eye before it stops. It seems to be the eyeliner itself, or maybe the slim applicator. I did not want to give up my wonderful eyeliner, so I kept buying new ones thinking it maybe had been stored too long. After buying about 6 of them from different stores, I have had to give up on my wonderful Loreal Super Slim eyeliner. It breaks my heart. I just wanted to let you know in case it is a manufacturing change. I know I can't possibly be the only customer experiencing this problem. PLEASE bring back the Loreal Super Slim eyeliner that we have always known and loved!!!!

Do Not Buy!!
I just bought this, it sucks. Absolutely horrible, completely disappointed. It’s dry, the brush gets ruined with the littlest pressure. I got the shade ‘Black/noir’, it comes out a dark grey. Completely disappointed, e.l.f. Or Revlon is a better choice.
