Works But Slow Results
I received this product complimentary for my honest review. I love my lashes and brows so anything to make them appear fuller and longer I'm all about. I've tried other brands of peptide serum and eye brow and lash growth products and felt this product was pretty on par with some more affordable bra...

Brows look slightly thicker
Hair Type Wavy Hair
This serum is applied with a thin brush for precise application on the lash line and on brows. It is a thin clear liquid that applies evenly. I did not find that the liquid left any residue like some of the other reviewers. I actually saw a very small change to the density of my brow hair. It is not incredibly noticeable but perhaps longer use will allow me to see more. There is very little product in in the tube so I think it may run out quickly.
Definitely works!

Brow improvement
Hair Type Straight Hair
I've been using this for a few weeks now and I would recommend. I was a bit wary that the packaging looked a bit dirty upon opening, but the product itself seemed fine and unused. My brows do seem a bit more grown in, but a bit difficult to tell for sure. It's easy to use, but I would say a bit pricey, losing a star.
Didn't see much difference
Hair Type Straight Hair
I received this product in exchange for my honest opinion. The product is okay, I haven't seen much difference but it might just need more time. The smell isn't too pungent, so definitely acceptable. Overall, it is an acceptable product.
