Not sure...
Pros: - easy to use - like putting on mascara - light and non-gluggy - affordable Cons: - not sure if I can see a big difference between using it and not using it

Good
Love this product!!!! I will purchasing this product again.

Use this on my brows and they never looked fuller!
Such a big fan, I love my brows now!

Did not make a difference for my lashes
Gel like consistency, no scent detected. Did not irritate eyes. I used this product on my lashes over a month and saw no difference in length or volume. Will not repurchase even though its very inexpensive.

Ok
Just okay... can’t really tell what’s happening with this
