I love this product, I can see my eyelashes are growing becoming longer and more full. The only one thing about it once you put it on you need to go sleep I noticed if I am still up my eyes get little irritated. But I can see the difference in my eyelashes so I would definitely recommend this product.

Customer Feedback:
I got this product to help address my dry eye symptoms and I didn't have many expectations about this product in regard to lash growth, but it totally works. My lashes are fuller, longer and less brittle. It took like 8-10 weeks to start seeing the difference. A little goes a long way, I use half a pump for both lashes.

Review Title: Very Nourishing!
Customer Rating: 4 out of 5 stars (Very Good)
Reviewer Name: Kathryn H. (Verified Purchase)

Customer Feedback:
I love the get growing lash & brow serum. I have been using this serum for almost 2 years. It can be a bit shiny, so I only use the serum at night. I have seen an improvement in the density of my lashes for sure. Minimal amount of growth in both lashes & brows, but more dense & very nourished. This is more of a nourishing & calming treatment I would honestly say. If you have dry eyes from seasonal allergies, dry eyes or any general eye irritation, this serum will definitely be a soothing solution.

This has been one of my favorite products I've tried from this line. It works well. I apply it to the base of my lashes and brows and then use a clean, dry mascara wand (I save up all the good ones for this purpose!) to sweep it up my lashes. I recommend this.
