Diaper rash creams are topical products designed to protect and soothe a baby's skin from irritation caused by wet or soiled diapers. These creams often contain ingredients like zinc oxide or petroleum jelly, which create a barrier to prevent moisture from coming into contact with the skin. They are typically applied during diaper changes to help prevent rashes. When a baby experiences a rash, these creams can help reduce redness and discomfort. It's important to apply the cream generously and allow it to dry before putting on a new diaper. Regular use can help maintain healthy skin and prevent future rashes.
