I havn't finished my course yet, but, I had the same thing. It was just getting worse and worse until about month 4. Constant 2 or more new ones each day. Then it started to die down slowly. I just got into month 5 and I only get like 1 spot week or two but red marks are still everywhere.

Basically, it works differently for different people. You might be one of the unlucky ones who it takes longer to work, but just keep at it!
