Review - New York Biology Eyelash Growth Serum

I received the new growth serum a week about and have been using it everyday. I have liked all all the all products I have tried by New York Biology, but this one I am not in love with yet. It is kind of had to put on. I think the brush should be a bit thicker. I have used it for 7 days and am going to give it a few more weeks and will update what I think. As of right now there is no difference, but that I am losing more lashes than I was. Not sure if it's coincidence or from the serum. I'll come back in a couple weeks to update how it's going.

Disclaimer: received this product at a huge discount for my honest unbiased run which I have used it every day since receiving the product.
