e.g. zinc oxide) and chemical ingredients (e.g. avobenzone / octocrylene), and re-apply every two to three hours — more often if exercising and / or swimming.
Traditional diaper rash creams have heavy oils and other ingredients in them (
e.g. zinc oxide and cod liver oil) that stick to cloth diapers, causing them to leak and retain odors.
