Good Product
This product does exactly what I was hoping it would do.  Over the past several months, I've found that after applying make-up in the morning, my face gets very oily only an hour later.  I saw this and decided to try it.  I brush it on after my face powder and it keeps my face matte and not shiny.  It's not 100%, but compared to before, I would say that there is 80% or better improvement.  (And it could possibly be even better if I were more thorough in my application.)  I would recommend this product.  (And no, I did not receive it at a discount for a review.  I paid full price.)
