GUIDE
Creams are lighter and absorb into skin — better for mild rash or prevention. Ointments are thicker and form a moisture barrier — better for active rash and protecting raw skin.
Most families end up using both, depending on the situation.

“If your child just seems to have a generalized diaper rash, it's best to keep the area clean using plain water and a soft cloth so that you don't irritate the skin even more. Allowing the air to reach that area can sometimes be really helpful.”
Dr. Jacqueline Kaari, DO, Pediatrician, Cleveland ClinicWalk down the diaper care aisle and you will see "cream" and "ointment" used almost interchangeably on packaging. They are different formulations designed for different situations. Understanding the difference helps you reach for the right product at the right time, instead of using whatever is closest when your baby has a red bottom.
Creams are emulsions — a mix of water and oil. They are lighter, absorb into the skin, and deliver active ingredients like zinc oxide directly to irritated tissue. They are your everyday product for mild redness and prevention. Ointments are oil-based (usually petrolatum). They do not absorb. Instead, they sit on top of the skin and create a thick, waterproof barrier that keeps moisture and irritants away from raw or inflamed skin. They are your heavy-duty product for active rash.
Most pediatric dermatologists recommend having both on hand. Use cream for prevention and mild redness. Switch to ointment when rash is active, especially if the skin is raw or broken. For severe rash, layer medicated cream under a thick ointment for maximum effect. If you are not sure whether what you see is diaper rash or something else, our guide to baby rash types can help you tell the difference.
| Aspect | Diaper Rash Cream | Diaper Rash Ointment |
|---|---|---|
| Consistency | Lighter, semi-solid emulsion. Absorbs into skin more easily. | Thick, greasy, does not absorb. Sits on top of skin as a barrier. |
| Primary function | Soothes irritated skin and delivers active ingredients (zinc oxide). Some barrier protection. | Creates a thick moisture barrier between skin and irritants. Stronger physical protection. |
| Best for | Mild rash, daily prevention, and situations where you want the product to absorb. | Active moderate-to-severe rash, raw or broken skin, and overnight protection. |
| Common active ingredient | Zinc oxide (10-40%), sometimes with soothing additives like aloe or vitamin E. | Petrolatum (petroleum jelly) or zinc oxide in a petrolatum base. |
| Application | Spreads easily, thin layer. Comfortable under clothes. | Thick application. Can be harder to spread on sore skin. |
| Examples | Desitin Daily Defense (13% zinc oxide), Boudreaux's Butt Paste (16% zinc oxide). | Aquaphor Healing Ointment (petrolatum-based), plain petroleum jelly, Desitin Maximum Strength (40% zinc oxide). |
Creams with 13-16% zinc oxide are sufficient for most mild rashes and daily prevention.
If cream alone is not resolving the rash within 2-3 days, switch to or add an ointment.
Plain petroleum jelly (Vaseline) is one of the most effective and cheapest barrier ointments available.
The mess is a tradeoff for effectiveness. For cloth diaper users, use a liner to protect the diaper from petroleum stains.
Tinylog lets you log symptoms like diaper rash, note the severity and treatment, and track how quickly different products work — so you know exactly what to use next time.
Most diaper rash resolves within 2-3 days with frequent changes, air time, and barrier cream or ointment. See your pediatrician if: the rash does not improve after 3 days of treatment, the rash has bright red borders with satellite spots (possible yeast infection), there are blisters, pus, or open sores, or the rash spreads beyond the diaper area. If the irritation seems more widespread or does not respond to typical treatments, it may be baby eczema rather than standard diaper rash. These signs may indicate a yeast infection, bacterial infection, or another condition that requires prescription treatment.
Is the skin slightly pink? Use cream. Is the skin red, raw, or broken? Use ointment. Is there an active rash that is not improving? Layer cream under ointment. Is the rash bright red with defined borders and satellite spots? See your pediatrician — it may be yeast. Your diaper type matters too — if you are deciding between cloth and disposable diapers, note that cloth requires more frequent changes. Is there no rash at all? You can use a thin layer of cream or ointment preventively, or skip it entirely. There is no rule that says you must use a product at every change.
For active rash, apply any medicated cream first (antifungal or zinc oxide), then seal with a thick layer of ointment on top. The cream delivers the active ingredient; the ointment locks it in and protects the skin. This layering technique is what many dermatologists recommend.
When rash appears, note the severity, what product you used, and how long it took to resolve. Over time, this data shows you which product works fastest for your baby. Some babies respond better to zinc oxide; others do better with plain petroleum jelly.
The most effective diaper rash treatment is frequent diaper changes and air time. No cream or ointment can overcome a diaper that stays on too long. Change as soon as the diaper is wet or soiled, and let your baby go diaper-free for short periods when practical.
