This really does work!
My lashes are much thicker and longer than before I used this. I love it and will continue to use it because it works! Who doesn't want nice thick longer lashes?

Nope
I did not see much of a difference. The application is difficult for lashes. It is much easier for eyebrows but the often would be white and flaking in the morning.

so far it's not irritating my eyes
Have been using this for about a week and so far it is not irritating my eyes. I was using a product made by Benefit that seemed to be helping my lashes but I was getting irritation. I liked that this product can be used on eyebrows as well. The brush is kind of a soft sponge - like a lipgloss applicator - that is slightly angled. Very easy to use.

It really works!
I bought this product because it was highly rated as an affordable way to get thicker eyebrows. And it really did work! I had pencil-thin eyebrows and now they have really filled in! I would definitely buy it again!

Doesn't work at all!
I've used the entre tube and can tell no difference. Do not recommend!

Took a bit of time to arrive
I am early days on using this grow potion. I do notice a bit more fullness in the brows, eyelashes, not so much. But happy with the brows.
