I didn't have any luck with ProActive. My skin is pretty sensitive, so the ProActive seemed to make it more irritated, red, and sore. I tried a bunch of topical treatments prescribed to me by a dermatologist, but these seemed to lose effectiveness after a month or so because my skin built up an immunity. I finally got really good results using a prescription face wipe and a pill (I can't think of the names at the moment, but can try to get them later). Also, since it's a prescription it was covered under my insurance.
I've also had some success with the Burt's Bees acne stuff, if anyone is interested in a slightly more natural solution
Does the stuff have Benzoic peroxide in it? I'm really allergic to it and get a pretty bad rash from it similar to what you've described. You might want to check the ingredients, especially the "active" ones (I think that's what they're called) to see if there might be something in there that you're allergic to. Some moisturizers actually have alcohol in them, which can dry out the skin. Usually baby moisturizers are pretty good for sensitive facial skin because they are made especially gentle.
