  • "After using it every day for a month or so I have noticed my eyelashes seem a bit thicker." in 1 review

It's pretty good. I use it every once in a while. I don't see much growth in my eyelashes but it is a great "eyelash primer". It makes the mascara you put on top less clumpy if ever clumpy. I would recommend to someone who already has long eyelashes that just wants a base coat.

I purchased this product at Walmart. I have purchased several bottles of this eyelash serum and I am always pleased with it. It truly does work and lengthening and strengthening your eyelashes, but you have to keep using it continuously in order to reap the benefits. Although the product does state that you can wear it under your mascara, I choose to wear this at night because sometimes the product (which goes on clear) can dry in clumps that resemble spider webs. 

I haven't been able to find this product lately in store and I am wondering if it has been discontinued. If I can find it, I am definitely going to repurchase it. I already have recommended it to friends and I recommend it to anyone else who is looking for an eyelash lengthening serum.

This product works! I used it religiously and always got compliments on my eyelashes and asked if I had extensions. Was able to find one recently and was so happy.

After using this consistently for over one month I found absolutely no benefits. My eyelashes didn't get longer, thicker, shinier... nothing. The applicator was a very awkward hard banana shape, I think a simple brush, like for liquid liner would have made the applying process a lot easier. Overall I do not recommend this because it will just waste your money and get your hopes up. You are better off taking Biotin.

As a makeup artist/addict I like to wear false lashes at times. I tried a new glue which upon removal also removed some of my lashes. I thought this would be great to try and maybe help my lashes a bit. I know it wasn't going to make then grow back in a month but I thought it help then get healthy again. I expected what it said it would do on the package. After more than a month I saw nothing, no difference. In my opinion with products like these it is better to buy high end

This lash serum works a little bit. I haven't seen a major difference in my lash color, length, or strength. However, if I use it as a mascara "base" it definitely plumps up lashes and darkens them a bit so you can use less mascara for the same desired effect.

If you really want to get major color, length, and strength results you have to use more expensive products. You need a prescription for Latisse, but it is so amazing!

Don't just use this whenever you feel like it, you have to use it everyday in order to see a difference, I'd say I saw a difference in about 2 weeks, that was using it every morning and at night before bed. Overall it made my lashes a little longer and thicker, and I pretty sure I had more coming in.

I used this product religiously day and night till I used it all up and it did wonders on my lashes. My lashes were noticeably longer within 2 weeks and a bit thicker. Although the moment I stopped using it, in about 2 weeks some of my lashes started falling off.

I haven't noticed much of a difference. My lashes are pretty sparse, thin, and light, and recently they have been growing (but that's from switching from makeup wipes to liquid makeup remover). The applicator on this was sooo awkward. Probably wouldn't get again.

I've always wanted to try a lash boosting serum but wasn't going to pay a high price for one. I saw this advertised and thought I'd give it a try. After using it every day for a month or so I have noticed my eyelashes seem a bit thicker. They are definitely more resilient. Once this is gone I will be buying it again!

Recently I got fake eyelashes done for a formal event, and they were amazing. When the lashes came off they pulled off a lot of my real lashes and I need a serum that is actually going to work to get me full and lengthy lashes. Does this serum actually work? And how long does it take to see results?

I recently ripped off my eyelashes using false eyelashes. I'm desperately trying to grow them back. Could this eyelash serum grow back hairs or just make hairs longer?
