Infallible Never Fail Eyeliner, Carbon Black

‘Never Fail’ that’s a joke as I can barely get a mark out of this on my eye lid & even testing on my wrist you have to press really hard to see anything. I’m so disappointed, especially as I was very keen to try it after reading fantastic reviews. I also had to wait over a month for this eyeliner to arrive. I’m now thinking it’s either a fake product or from very old stock for it not to work like this.

Good product

This is my absolute favorite eyeliner ever. I know that everyone's preferences/interactions are different when it comes to cosmetics, but this one works the best for me. I have been using it for several years now and it is the only one I will continue to use, except when I want to add some liquid liner for a special night out. I prefer a more smudged eyeliner look than a hard and straight line, so this is ideal for me since the eyeliner itself is softer than a pencil and it has the smudge tool. Since I smudge it anyway, I can apply this relatively quickly without worrying about getting a perfectly straight and even line. Even though it is softer than a pencil, it is not so soft as a liquid liner/brush, so it is easier for me to control and apply and it is dry right away. It is dark, but it is not as dark and defined as a liquid liner. You will get a slightly different look depending on whether you apply it before eye shadow or after. Eye shadow will stick to the top of it, so it's less defined (more blended in?) if you apply the eyeliner first. If you apply the liner after the shadow, then it takes a little bit more effort because the liner will kindof wipe away the eye shadow first before it actually sticks to your eyelid, so you have to make a couple passes. But the end result will be a bit more definition of the line. And there is obviously more definition if you don't smudge it afterward. When I want a darker, more defined line, I use this liner as a sort of primer to liquid liner. I will apply this one and smudge it in as usual, then top it with a thin coat of liquid liner. More color and definition, but less worry about making the liquid line 100% correct and thick since the undercoat of liner shades in any gaps. It also comes with a sharpener attached to the smudger, but I never use it since I'm not going for that thin/defined line and I'm smudging it anyway; sharpening the crayon just wastes product. Once applied, it lasts me all day as long as I'm not rubbing my eyes or something. Even after swimming or sleeping, there is enough there to still look ok (again, since I smudge it...if I was going for a defined thin line, it probably wouldn't look right after swimming or sleeping). The only problem I have with this eyeliner is the casing - the clear smudger cap breaks and detaches easily in a bag and the casing around the smudger/sharpener cracks easily which causes the smudger/sharpener to fall out completely (and it always ends up at the bottom of my makeup bag, of course). The crayon itself often detaches from the retracting mechanism so that you can only advance it and not retract it.

Love this eyeliner and have ordered many times, price is good too. I have used this eyeliner for at least 10 years, easy to put on and stays on!

I’ve been loyal to the L’Oreal Paris Infallible Never Fail Mechanical Pencil Eyeliner (0.008 oz, Black) for years, and it’s still my go-to for everything from daily work looks to dramatic evening vibes. Priced around $8-10, this eyeliner is a steal for its creamy application and all-day staying power. It’s become a staple in my makeup bag, and I can’t imagine switching to anything else. If you want a reliable, versatile eyeliner that’s easy to use and travel-friendly, this is it! What I Love: Smooth, Effortless Application: The creamy formula glides on like a dream, whether I’m lining my upper lid or tightlining. It’s pigmented enough for bold lines but blends beautifully for smoky looks, thanks to the built-in smudger sponge. No tugging or skipping, even on rushed mornings. Clever Built-In Sharpener: The sharpener tucked into the opposite end is a genius touch—perfect for keeping the tip precise without needing an extra tool. It’s easy to use and ensures crisp lines every time, whether I’m going for sharp wings or a soft, blended look. Long-Lasting and Gentle: This eyeliner stays put all day (8+ hours!) through work, workouts, or humid weather without smudging or flaking. It’s ophthalmologist-tested and doesn’t irritate my sensitive eyes, which is a huge win compared to other brands I’ve tried. Purse-Perfect Size: The sleek, compact design fits easily in my purse or even a small clutch for quick touch-ups on the go. It’s lightweight but sturdy, so it doesn’t feel cheap or break in my bag. Any Downsides? None that bother me! The sharpener can collect some product residue, so I wipe it clean occasionally to keep it pristine. It’s slightly pricier than drugstore alternatives, but the quality and features make it worth every penny. Final Verdict: The L’Oreal Paris Infallible Never Fail Eyeliner is a makeup must-have that delivers flawless results every time. Its smooth glide, long wear, and handy sharpener-smudger combo make it perfect for beginners and pros alike. I’ve repurchased it in Black and Brown multiple times and will keep doing so—it’s that good! Whether you’re creating everyday looks or dramatic cat-eyes, this eyeliner won’t let you down. Highly recommend for anyone who wants effortless, eye-safe perfection!

This Infallible Eyeliner by L'Oreal is very reliable and works great. It goes on smoothly and lasts a long time. I have other eyeliners but I prefer this one. I like the smudger tip on the end of it. I bought the carbon black which I think is a bit too dark for me but that is my mistake. Next time I will just buy regular black. I like the fact that it is sturdy and soft at the same time. I have used this eyeliner for a long time and never had the point break.
