Did not work on my stubborn acne

Unfortunately this product did not work on my stubborn acne. I had high hopes for it, especially for the price, but no luck! It also stings upon application.

When you first apply this product, it feels as if it's doing something because, for me, it made my skin tight. Unfortunately, when I would wake up after applying it the night before, my skin looked shiny and the blemishes were not at all improved.
