Cornstarch is a popular remedy for diaper rash, but doctors don’t recommend it or talcum powder, another commonly used diaper rash remedy. Talcum powder is bad for a baby’s lungs, and tends to be inhaled easily. Cornstarch can make a diaper rash worse if it was caused by a yeast infection.
Using Cornstarch to Treat Diaper Rash
- People who use cornstarch to treat diaper rash either sprinkle it on the baby’s dry bottom, or apply a layer of petroleum jelly or another soothing ointment, like Milk of Magnesia, first.
Why It Works
Cornstarch absorbs moisture, so it may help if excess moisture is the source of the problem. However, excess moisture in a diaper usually comes from urine, so changing diapers more frequently may be a better solution.
Cornstarch can make a rash worse if the rash is being caused by a yeast infection. If you do choose to use cornstarch to treat diaper rash, keep a close eye on the rash to make sure that it is not getting worse. If it does get worse, discontinue use of the cornstarch and check with your doctor.
