## Customer Reviews

### ⭐⭐⭐⭐⭐ AMAZING!!!
*by S***E on April 8, 2017*

I am totally in love with this miracle serum! I suffered from a terrible eye infection which caused me to lose all of the eyelashes on my right side. Constantly using falsies so that I could feel feminine and a little less, like everyone staring. That process usually ended in a huge disaster and even bigger tears though. I did quite a bit of research on eyelash enhancement products once my eye was back to normal and kept coming back to this particular product. And I am so glad I did! I saw new growth within the first few applications and now I have enough to wear mascara again. This is the one and only beauty product I have ever used in my thirty year's of existence, that actually produced results as advertised! I have recommended this to everyone I know and plan to reorder more in the near future. I am beyond impressed.

### ⭐⭐⭐ The product is not super great but works a little bit
*by R***S on October 27, 2016*

I noticed a very, very subtle difference on my lashes. The product is not super great but works a little bit, because my lashes seem fuller than before, but not a whole lot though.

### ⭐⭐⭐⭐ Bought these for my girlfriend - I've noticed growth!
*by A***R on December 10, 2017*

So I don't usually post reviews here, but I thought maybe this can help others out. Anyways, mi girlfriend showed me this and wanted me to get it for her as a gift. I told her that she didn't need it, because I think that she is beautiful no matter what, outside and inside. But anyways, being the boyfriend that I am haha, I got it for her anyways.I don't watch her when she puts it on but she never complained at all about it. But actually, I've definitely noticed my girlfriend's eyelashes get longer since she started! It's been about a month now, and I look in her eyes everyday. Growth is relatively fast (not overnight-fast, but I think I actually first noticed a difference in around the 2 week mark from when we received it). Like I said, it never really mattered to me, but she's happier, so that makes me happy lol!Side note to all the women on here: use this just as a tool for growth, but not as something that you rely on to feel pretty. It's not a NEED because you are all beautiful, I don't care what anyone else says. And you know it deep down inside too. Don't compare yourselves to anyone else because your uniqueness is beauty in itself. :)
