You need to give any acne treatment more than 2 weeks to see if it's going to work - more like 8 to 12 weeks before you can make a decision if there's been any improvement or not. To be honest the only things that worked for my acne was Dianette, but you can't be on it for too long, I think a year or two at most. I'm now on a new contraceptive pill called Yasmin, which works well, though not as good as Dianette.
