Hope this helps some of you guys...
I found that I was getting the acne too after continuous usage of the orange.
Anyway, one thing I've used very successfully for the last couple of years for pimples is tea tree oil. If you catch them before they actually erupt, you can stop them completely. When you start feeling those little sore, slightly raised bumps, dab them with a little pure tea tree oil once or twice a day, and they will completely disappear before erupting.
I picked some up last Thursday because I was feeling and seeing sore, red spots start, and applied it once on Thursday and Friday - and the completely disappeared without errupting by Saturday. Since I was out camping all weekend, I even admit that my hygiene wasn't the best throughout this time (dirt, woodsmoke, infrequent showering, etc), and still they never erupted.
I think I picked this tip up from Diane Lane (a beauty author), and it has never failed to work. But you have to catch them before they hit the surface of the skin.
It's worth a try if you want to continue the P7 but are having trouble with acne.
