I know this is an old thread, but maybe this will help someone. I use Black Seed Soap to keep my PR at bay. It works pretty well. The only downside is it is a moisturizing soap so it may not be good for someone with oily skin. I have dry skin and use it all over except on my face, neck, and chest where my skin tends to be oily - so on the rare occasion that the PR pops up now, it only comes up on the areas where I haven't been using the soap (neck and chest). And when I have stopped using the soap (eg once when it ran out and I didn't replace it immediately), the PR comes back almost immediately and persistently. BLACK SEED SOAP!
