When I was using this at the time I had pretty moderate acne with some small cysts. I used it as a spot treatment and used up half of the bottle up an was ehh about it. For me it was ok didn't irritate my skin but didn't really do much for my spots. I felt like it took forever for the pimples/cysts to go away when using it. The only thing I liked about it was that it made my spots less red. But other than that it wasn't great for me.
