The most effective treatment, although not always the most practical one, is to discontinue use of diapers, allowing the affected skin to air out. Other commonly recommended remedies include oil-based protectants, often using various over-the-counter “diaper creams”, but sometimes people use petroleum jelly and shark liver oil or cod liver oil; zinc oxide based ointments, and, in extreme cases, anti-fungal cremes. Low concentration hydrocortisone creams are also sometimes used to treat the symptoms of diaper rash, although they do little to clear up the rash itself. Some claim that discontinuing the use of baby “wipes” can be effective in alleviating the symptoms of diaper rash.
