How to Treat Diaper Rash With Cornstarch

Diaper rash is a common skin irritation that babies will more than likely experience at some point while wearing diapers. According to the American Academy of Family Physicians, diaper rash is caused by skin irritation from a diaper that is too tight or a soiled diaper that is left on for too long 1. Diaper rash can also occur from antibiotics being taken by the baby for infections or by a nursing mother. Diaper rash can be very mild with just a bit of redness in the diaper area, to more severe with open sores and blistering around the affected region. Although diaper rash is very uncomfortable for the baby and heartbreaking at times for parents, eliminating diaper rash can be a very simple process.

Remove soiled diaper and wash area with a mild soap using a cloth or soft face towel. Do not rub the skin too hard to avoid further irritation. Severe diaper rash can bleed if rubbed roughly.

Rinse soap off the skin after all waste has been cleaned from the skin and carefully blot the skin dry with another cloth.

Let the skin air dry for just a few moments which will ensure that the skin is completely dry and allow some of the cool air to soothe the skin. This is a great time to play and bond with the baby who may be a little cranky from the pain of the diaper rash.

Apply cornstarch to the skin by lightly sprinkling it directly on to the skin. A paste can also be made by mixing petroleum jelly and cornstarch together and applying it to the skin. Petroleum jelly is a great barrier against moisture.

Place a fresh cloth or store brand diaper on baby. Monitor the rash periodically and change diapers frequently, following the same process until the skin fully heals.


Certain causes of diaper rash can be made worse with the use of cornstarch such as rashes caused by yeast infections. If the rash becomes worse after the first application of cornstarch, discontinue use and use only petroleum jelly or an over-the-counter diaper rash ointment containing zinc oxide.
