Diaper cream is a topical ointment designed to protect and soothe a baby’s skin, particularly in the diaper area. It is commonly used to prevent and treat diaper rash, which can occur due to moisture, friction, and irritation from urine and feces. Most diaper creams contain ingredients like zinc oxide or petroleum jelly, which create a barrier on the skin. Parents typically apply diaper cream during diaper changes, especially if they notice redness or irritation. Regular use can help maintain healthy skin and prevent rashes. Many brands offer various formulations, some with added soothing ingredients like aloe vera or calendula.
