Love this product. The brushes are a bit rough for the eyelashes, but I see that you have to get the product into the skin. I notice a result right away. My lashes where dry and very thin, could not see them even with mascara and after a week they were long and beautiful. Starting to fill out. Would suggest this product for women who has thin and problem eyelashes. I have never written a review on any products, but believed this product deserve a review.
