Review: Long Time Fan! - I've been using this product for seven years and will continue to use it for at least 7 more years! Why I love it: 1. It doesn't irritate my sensitive eyes. 2. It actually works- the serum thickens and lengthens my eyelashes, as per the product description. When I run out and forget to reorder, I notice a difference in my eyelash length, so it's definitely is the serum that's causing my eyelashes to thicken and lengthen. 3. The lash brush makes it easier to apply than other eyelash serums. 4. I apply the serum at night after I take my contacts out, take my makeup off, and do my skincare routine. I've found that applying the serum at night also helps get off any lingering mascara. 5. The price- so affordable! Especially compared to other brands/similar products. 6. The serum is also great for eyebrows! The same lash brush can be used on both eyelashes and eyebrows without residue from each other.
Review: Feels nice, but idk if it works for eyelashes - Well my lashes definitely feel healthier. I don’t see any growth after a month, but it does help curl my eyelashes upward which makes them look longer I guess. They’re super nice to put on my lashes and brows, but it does sting if it gets in my eye. Overall it’s a nice product, but I think it’s more of a lash primer than a serum. Update (1/11/24): I realize now that since putting it on my brows they HAVE gotten considerably thicker. So that's yay, but I'm going to buy again to see if it'll help with my lashes. Nice product! Update (1/9/25): After about a year of use, not even consistent, my eyelashes have grown and are fuller/healthier! It works!

**Q: Can you put it on your lashes with your finger to get it on the roots?**
A: I swipe it with the applicator and use my finger to rub it in. I also use it on my eyebrows!

**Q: should I disinfect the wand? or will my eyes be ok.**
A: If I was doing that, after disinfecting, I would wash and rinse the wand thoroughly and let it dry completely (meanwhile cover the tube with a bit of clean plastic wrap held in place with a rubber band so the stuff doesn't dry out) because I wouldn't want to get disinfectant in my eyes.

**Q: does this get flaky after a while?**
A: It hasn't happened to me and I wear it for long days and it takes me a long time to use up a tube.. It does tend to clump a bit on my eyelashes after I've worn it awhile no matter how good it looks when I start out

### ⭐⭐⭐⭐⭐ WORKS but itches?
*by K***N on April 8, 2024*

I already have long lashes, but I get a little nervous when I do my lash extensions and some fall out, so I bought this because I wanted my lashes to still grow when I didn’t have lash extensions in. it is spring and I have HORRIBLE allergies, so I ultimately can’t tell if this is the lash serum doing this or just my allergies, but I feel like if any formula gets in my eye, it gets VERY red and irritating so maybe beware of that. it definitely works, but GOD I think it makes your lashes super dry!! maybe carry some eye drops with you. Also be careful of exactly where you apply because applying this made a lash grow out of my waterline and I had to pluck it out (it hurt..)
