Help!

This is the end of my 3rd week on the regimen. I've been following it exactly using all the acne.org products (I hate the moisturizer, but that's another story). I've had significant acne reduction, and a couple days ago my skin was almost fully clear!

But yesterday morning I woke up with TERRIBLE acne on my cheeks that continues to worsen. I've changed nothing about my routine or the regimen.

Has anyone else had this happen at this stage of treatment? And if so, what helped you? Please advise.
