Is Cornstarch Good For Diaper Rashes? A Pediatrician Explains
There are better options.
Babies are famous for having incredibly soft skin, but that velvety smoothness comes at a price: Itchy, painful rashes. That's especially true in the diaper area, of course, and there's nothing like a raging diaper rash to put a baby in a horrible mood. You'd try just about anything to make it go away, and there are tons of baby creams and ointments to choose from. Still, lots of parents swear by straight-up, old-fashioned cornstarch. Seems harmless enough, and it's certainly affordable. But is cornstarch good for diaper rashes? And, most of all, is cornstarch safe to use on babies?
Is cornstarch good for diaper rashes? Is it safe?
Cornstarch for diaper rashes has been a home treatment “used for many generations,” as pediatrician Natasha Burgert, M.D., tells Romper. But while Burgert says it is considered “likely safe to try,” that doesn't mean that cornstarch helps with diaper rashes much, either.
“We don’t recommend cornstarch,” Dr. Burgert says. And yet, some moms claim cornstarch for diaper rashes is just plain magic. Scroll through any of the many diaper rash remedy message boards out there and you'll find countless testimonials to the effectiveness of this simple home remedy. So, what's the deal?
Basically, how successful cornstarch or any other treatment will be in treating your baby's diaper rash depends on what's causing the rash in the first place, Burgert says. Usually, diaper rash is triggered by a combination of too much moisture, too little air, friction, and irritants (the contents of your baby's diaper, the cleansers in baby wipes, bath products, and so on. Diaper rashes themselves can fall into one of several categories, including chafing (the most common type), yeast, intertrigo (a red area that can ooze), impetigo (a bacterial infection), and eczema.
What to try instead of cornstarch for diaper rashes
“Most doctors recommend lubricating emollients for diaper rash to keep a moisture barrier intact, rather than trying to wick moisture from the skin,” Burgert suggests.
The way you treat your baby's diaper rash will depend on the type. Aside from regular old diaper creams, you might try simple measures, such as keeping baby as dry as possible — in other words, changing them as soon as you suspect a wet or dirty diaper — and giving them some good diaper-free time to let the problem area breathe. If you’re ever concerned there is something more serious going on — or feel unsure about what treatment might be best — you should always feel free to contact your childs doctor.
You might have heard some people (even medical professionals) say that cornstarch makes yeast-based rashes worse. And older study published in the journal Pediatric Dermatology found that cornstarch was shown to minimize and protect against irritation from friction, and did not enhance the growth of yeast on human skin. A recent study published in the Journal of Drugs in Dermatology used cornstarch in conjunction with a natural cream to test it's effectiveness as a barrier and found that it was over 70 percent effective with no adverse affects.
While talc-based baby powder was once found on changing tables everywhere for this reason, the American Academy of Pediatrics advises against using it because babies can easily inhale the particles, causing harm to the lungs. (Cornstarch is also a powder, but it's talc-free.)
Because cornstarch is so cheap, you've essentially got nothing to lose by giving it a shot. Just be sure to use it sparingly, and keep it away from your baby’s face. And, naturally, if your baby's rash doesn't respond to this or any other home remedies, call your pediatrician.
