I think that changing the type of soap you use, may trigger a break out. I use Dial, the yellow antibactieral soap. If I use any other soap, I break out. I think part of the reason is that my face is 'used' to it. I notice I also break out during the change of seasons. When it just changes from winter to spring, I always get a bad break out. I also noticed that to get an appointment with my dermatologist around this time is harder so I think this effects many other people.
