I haven't had my skin break, but I get chafed easily in some area, including folds. I asked a nurse practitioner (because the medical office I went to then often had patients seeing nps instead of doctors) about the problem. At that time, I also had a problem where the chafed area would sometimes smell really bad, apparently because of a fungus. She gave me some cream to clear up the fungus, and told me to use unscented Ban antiperspirant solid after drying off well after showers. I haven't had any major problems since! I actually use unscented Secret solid right now, because I couldn't get Ban once, and tried Secret instead, and that seems even better. Just make sure you dry the area (don't rub so hard you chafe) after showering, then put the antiperspirant on.
