I, too, had problems with acne shortly after starting my CPAP therapy. I've been through four different masks now and, wherever each mask or headgear touches my face for any extended period, a few pimples would crop up.
The solution that seems to work best for me is:
1) Using a facial cleanser such as SeaBreeze right before bed
2) Daily wash and rinse of all mask parts
3) Bi-monthly wash and thorough rinse of the headgear
Unless you're having an allergic reaction to the mask or headgear material, this will probably do the trick. I also think that, as the weather cools down, you're less likely to sweat under the mask, which should also improve things.
