4D Silk Fiber Lash Mascara - Natural Waterproof, Smudge-proof, Thickening & Lengthening, No Clumping, Lasts All Day

One of the best mascaras I have ever used. It lengthens your lashes without looking clumpy, I rarely get smearing underneath my lower lashes, and it really is waterproof. I have been using this for years.

This is the best mascara I have ever used. I am 55 years old and have tried them all I think. L’Oréal Lash out from the 80’s was the only thing that ever came close and this is BETTER! I am blessed with some disposable income and have tried many many products including very expensive ones. This stuff does not flake, does not smudge, does not clump. It comes off easily with soap and water. It might have fairy dust inside. Do not bother with any other mascara. This is the holy grail.

I reordered this mascara because I really liked how it added length and volume to my eyelashes. It is easy to apply and there is very little clumping. Stays on with no smearing. The wand itself is sparkly and beautiful. It does need to be removed with eye make up remover, but that is not an issue for me. So based on my positive experience using it, I reordered again, even ordering another for my daughter. However, when I received my order, the package was empty except for a sale receipt. Package had not been tampered with in any way so I have to assume it was sent empty. However, Amazon customer service agent quickly rectified situation by sending in another. As far as the product itself, I am pleased with the results.

Best mascara, beats the most expensive ones. It doesn’t end up looking like I have black eyes at days end. Washes off easy but doesn’t smudge. Will buy again

I was looking for a tubing dupe for a much more expensive major brand as my toddler previously decided to flush that one down the toilet 🙄🙄🙄 and came across this one. It has surpassed my expectations and I’ll be reordering this one vs the famous “teal packaged” one that’s like 4x more expensive. Lasts all day, even with oily skin & hooded lids. ❤️

Actually not sweat proof. So not waterproof. Had it coming off my lashes and onto my bottom lids. But it does look nice while on. So I’m mixed. It doesn’t run, just not completely waterproof.

I gotta say, the case alone makes this mascara AMAZING! So gorgeous! As for the mascara itself, I’m pleased with the performance. I don’t have a lot of lashes, and it didn’t seem to add a lot of fullness, but it definitely added length! I read a couple of reviews before I bought saying it wasn’t a fibre mascara as it’s advertised, but I disagree because of the way it removes. Regular mascara liquifies and smears on removal. Fibre mascara comes off in pieces and that’s what this did. It stayed on well, except when my eyes got teary and I rubbed one it left a couple of remnants on my face that I easily wiped away. When I washed my face I splashed it with water first and the mascara stayed put and didn’t run. Mascara ALWAYS runs on me. I must have some super powered tears that eat through all mascara, waterproof and all. Fibre Mascara is the only thing that I’ve found that doesn’t run on me, and after a day of wearing this along with moisturizer under my eyes, this seems to be a quality mascara that doesn’t run and performs exactly as advertised. I’d recommend this!

I love this mascara but I am sadly switching to a different brand because when washing this mascara off, black chunks get everywhere! When I shower and wash my face , its black specks all over the shower curtain and tub. When I wash my face at the sink, black specks get stuck the sink! I have never had a mascara do this before. And although I really like the product and it washes off my eyes easily, Im left with a mess to scrub clean when Im done.

This is a great product, at a fantastic price point. Its water and sweatproof but still easily cleans off your lashes at the end of the day. I love the look length on my lashes, with very little chunking! I'm also highly sensitive to most mascaras and find no allergies at all with this product.

I wasn't expecting much from this mascara but I turned out to be quite pleased. It has good staying power and covers the lashes well. I do definitely recommend having a secondary brush to comb over the lashes once applied because when you first start using it, it can come off pretty thick on the lashes. It doesn't clump if you comb it out though.

In a former review I thought I was reviewing eyeliner. This is cruelty free which means a lot to me. I little flaky and extra time in removing but overall I am satisfied

I was convinced to buy this mascara due to all the super positive reviews. Reviewers, as you can see, rave about the lengthening and thickening properties of this mascara. There are even photos! Which makes me wonder if I received the same product as everyone else? **What I like about this mascara: It is a nice glossy black. It separates lashes REALLY well. It does not clump. It does not cause your lashes to stick together. It stays on nicely throughout the day. I even put this mascara on my bottom lashes, which typically causes me to get black raccoon eyes - but the mascara stays put on my bottom (and top) lashes. **What I don't like about this mascara: I could not discern much lengthening, and absolutely NO thickening, even after multiple coats. **BOTTOM-LINE: If you would like a natural looking mascara, that is glossy black, separates lashes well & does not melt or run, even on the bottom lashes, then this is the mascara for you. If you are expecting dramatic lengthening and ANY thickening, I would give this one a pass.

If i could rate this product 100 stars I would do it in a heartbeat!!!! This mascara doesn’t smudge at all. I wore it at work for 12 hours and when I got home my eyes are still perfect! No smudges, no panda eyes! I sweat a lot at work but not a single black mark on my eyes! Best mascara ever! Can’t even compare to any high end mascaras I got!
