This mascara fulfills its functions well. Sometimes the lashes tend to stick together, but with something sharp I manage to separate them. My lashes look thicker and longer.

Why buyers reorder it
One tube, two mascaras
Repeat purchases are common in the reviews - several buyers are on their third order, comparing it favorably to mascaras that cost far more.
Length or volume, your call
One end is built for lengthening, the other for thickening - use either alone or layer both for a fuller look.
Silk fiber, not just pigment
The fiber formula wraps and builds each lash rather than just coating it, which is what gives the visible length and thickness.
Holds through the day
Multiple buyers specifically call out that it stays put for hours without flaking - a common complaint with cheaper mascaras.
Easy to remove
Despite the hold, reviewers note it comes off easily with normal makeup remover - it isn't the stubborn kind that needs scrubbing.
Getting the most from it
Thin layers, let each one dry
The most common complaint - smudging - almost always traces back to applying too much at once.
Start with the lengthening end
Build your base coat first, brushing from root to tip in one motion.
Let it set before the second coat
Give the first layer a few seconds to dry before going back in - this is the single biggest fix for smudging.
Add volume sparingly
Switch to the thickening end for just the outer lashes if you want more drama without clumping in the center.
Separate while damp
If lashes stick together, a clean spoolie or the tip of a pin separates them cleanly before it fully sets.

Excellent mascara for the price. It increases volume and separates lashes well - it feels like it wraps around each lash and seals it.
According to the advertisement. I've bought before and it's very good. I really like this mascara, it delivers what it promises.
In general I liked the effect, but you need to wait for it to dry as it smudges a bit. I have used better mascara before.
Beautiful mascara. It has two modes, lengthening and thickening. I highly recommend it because the product is truly high quality.
It's very similar to a well-known original brand and I will buy again - all my mascara works amazing no matter the brand.
Well packaged, shipping was fast, delivery was very good. The brush thickness is right, not too thick or too thin, no bad smell.
Quick delivery and true to photo, great quality. I have very straight lashes but after a heated curler and this mascara it stays curled from morning till evening.
Super fast delivery. Second time buying this mascara. Very pleased with it - the best mascara I've bought on Ali.
Good mascara for a good price, holds well, does not fall apart during the day, easy to wash off. I only use the first brush mode since the second picks up too much product.
I have been using it for three years. It applies well, doesn't clump, and is easy to remove. Most importantly, it lasts long.
Second time I've ordered this mascara. It's amazing, lengthens and thickens with excellent hold.
The best mascara at a fabulous price - been buying it for years, everywhere else is $30+ for the same quality.
Fantastic mascara. Makes eyelashes long and thick. I wouldn't say it's fully waterproof since it can smudge, but still well worth the money.
If you are looking for mascara that lasts, this is excellent. I put it on and it stayed on without running for almost 3 days.
There's a plus right there, very interesting concept - looks like it will be messy but we'll see.
My partner says the formula is amazing, and she has used a lot of them, even from well-known brands. I definitely recommend it.
This mascara looks good and the packaging is high quality, but it gives almost no effect, just a little black color on the lashes.
I loved it, it's good quality, it doesn't smudge, it's not clumpy, it's lightweight and looks great.
Haven't used it yet, it looks to be of good quality and has a good price, arrived quickly.

Before you buy
Straight answers
The two questions we hear most: does it smudge, and which end do I use.
Ask a questionIs it waterproof?
It's water-resistant, not fully waterproof - a few buyers noted it can smudge with heavy tears, sweat or rain. For everyday wear it holds up well; if you need true waterproof for swimming, this isn't that.
Which end should I use first?
Start with the lengthening end for your base coat, then use the thickening end on top if you want more volume. Using the thickening end alone, first, tends to pick up too much product for some buyers.
Why does mine smudge?
Almost always this comes down to applying too much at once, or a second coat before the first has dried. Thin layers, given a few seconds to set, fix most smudging complaints.
Does it clump?
Some buyers with the thickening end note lashes can stick together if too much product is applied - separate with a clean spoolie while it's still slightly damp.
How do I remove it?
Standard makeup remover works fine - it isn't formulated to resist normal removers, just to resist smudging during wear.
