I just came to this site to try and learn more about Acne & Rosacea, saw your post, and thought I'd pass this along. If you can obtain some Bentonite powder, mix about 2-3 tablespoons with just enough spring water or organic apple cider vinegar to make a light paste, and use it as a facial mask for 20 minutes. Wipe off and rinse excess from your face, and apply a light, non-clogging moisturizer. Repeat 2-3 times per week as necessary.
I've read of people using it for the purposes you mentioned, and hope it works for you too.
