Why do you have a problem with staph bacteria infection? The infection improves with barrier ointment since less gets in. Of course, moisturized skin feels better than dry skin. Peeling lips is like cracked skin when the layers come off.
My current hypothesis is both bacteria and fungus infections. I think Sargvy wrote that he believes this is an internal infection, which is also in the mouth. So, you really need to address the systematic infection. However, the mouthwash is good as daily measure to decrease bacteria or fungus in the mouth. I do not know if some of us have both bacteria and fungus infections...that would make sense if it is an immunity problem.
