My Go-To Mascara for Years — Makes My Lashes Look Fuller and Longer!
Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer
I’ve been using this mascara brand for a few years now, and it’s never let me down. This particular two-in-one (primer + mascara) combo works so well — it gives my lashes a great boost and really helps them look fuller and longer over time with consistent use.
Every time I wear it, I genuinely feel more confident and put-together — it just makes me look prettier, and that’s always a plus! The primer adds volume and helps the mascara go on smoothly without clumps. It lasts well throughout the day, too.
If you’re looking for a reliable mascara that delivers results and enhances your natural lashes, I definitely recommend this one!

okay so far
Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer
bought this because i have recently developed a sensitivity to heavy makeup around the eyes. loved the ingredients of this mascara and rates a 3 on the think dirty app (amazing app check it out!) that being said, i honestly didn’t expect any crazy results like i would with my prior mascaras (l’oréal lash paradise and maybelline lash sensational) and i was right, it took forever for me to apply a decent amount to my lashes.
both sides seemed kind of dried out too, not the thick consistency that people were talking about in the reviews. the primer was dry and sort of settled in clumps around my lashes and i did the best i could to comb them out but i ended out plucking out the clumps with my finger tips. the mascara itself was very thin but no clumping, just felt dried out like i said. my lashes fell straight in a matter of half an hour.
it also flaked throughout the day and i spent it entirely indoors. i rubbed my eye once or twice and my inner corner felt a little irritated but im not sure it’s because of the product itself. the packaging itself is a little bulky when applying but i guess it’s a matter of working with it. i think it’s a little pricey for what it is but i think i can work with it, given that i don’t want harsh chemicals around my eyes. i will continue to be on the hunt for a “clean” mascara that works better though

Sensitive eyes, and actual visible LASHES now.
Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer, Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer
I've gone through so many different mascara products to be able to try and find the ones that are going to work with my sensitive eyes.
I have blonde eyelashes that stick straight out and are very long for them being blonde.
I was using physicians formula for years and years and years and years and then it got to the point where they switched the formula recently?
And I was not getting any desired results. On a whim I decided to buy this even though it is about 10 to $12 more than what I would normally spend and I was blown away.
I love the pre mascara coating, and the mascara is just so clean and so soft... It's easy to remove stays in place!
It does not budge.
This is a quality product 10 and a 10 100 out of 10 if I could vote it that way. Fair-skinned fair eyebrows fair eyelashes we just want to have normal looking lashes.... That's all we ask in this product delivers!

It actually is the best
Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer
This mascara has apparently won awards, as it should have! This is the first mascara I have ever used in 20 years of wearing mascara that doesn't smudge around my eyes.
The key is obviously the primer. I'm obsessive about priming something before painting it, because it makes all the difference. No wonder it makes all the difference with makeup, too.
Great applicator. Product lasts for about 5 months for me, with near-daily use. Works great all the way until the tube is empty. Also thankful of course that it is a clean brand.
About to purchase for the 4th time.

Great mascara with two small flaws
Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer
I really like this mascara. I was using mascara which was not labeled as using clean ingredients. I switched to this one and after a few weeks, I noticed my eyelashes were longer, fuller, and healthier. The only problems I have had is it clumping my eyelashes quite a bit and it flaking throughout the day, adding to my permanent dark circles under my eyes. A lash comb fixes the clumping pretty easily and I have just learned to wipe under my eyes throughout the day to get the flakes off. Knowing the product I'm using is clean and safer than others is worth those two small inconveniences.
