Almost every baby gets diaper rash at some point, and a good barrier cream is one of the least expensive, most-used items on the changing table. The four products below are the top four sellers in Amazon's Diaper Creams category, with more than 215,000 ratings between them. They are not interchangeable: two are thick zinc oxide pastes for treating a rash, and two are ointments best used to prevent one. Here are the best diaper rash creams of 2026 and when to use each.
Desitin Maximum Strength Diaper Rash Paste
Desitin Maximum Strength is the number one best-selling diaper cream on Amazon, with more than 51,000 ratings. It contains 40 percent zinc oxide, the highest level available without a prescription, in a thick white paste that sits on the skin and seals out wetness.
This is a treatment cream. When a rash is red and angry, a thick layer of Desitin at each change, especially before a long overnight stretch, gives the skin a physical barrier so it can heal. Desitin says the paste stays in place for up to 12 hours. It is hypoallergenic and free of parabens and dyes.
The paste is thick, sticky, and hard to wipe off, which is the point, though it does make changes messier. It also has a distinct medicinal smell. Most families keep it for flare-ups rather than every change.
Best for: Treating an active, red diaper rash and protecting skin overnight.
Active ingredient: 40% zinc oxide
Size: 4.8 oz tube
Price: About $8
A+D Original Diaper Rash Ointment
A+D Original is the best-selling prevention ointment and has been on changing tables for more than 80 years. It is a smooth, translucent ointment based on petrolatum and lanolin, with vitamins A and D, that spreads easily and forms a moisture barrier between skin and a wet diaper.
Because it glides on and wipes off without scrubbing, A+D is the kind of product parents will actually use at every change. That consistency is what prevents most rashes in the first place. It is also useful for chapped cheeks and dry patches.
A+D contains no zinc oxide, so it is not the strongest choice once a rash has taken hold. It also contains lanolin, which a small number of babies are sensitive to. For daily prevention at a low price, it is hard to beat.
Best for: Everyday prevention at each diaper change.
Active ingredients: Petrolatum and lanolin
Size: 4 oz tube
Price: About $6
Aquaphor Baby Healing Ointment
Aquaphor Baby Healing Ointment is the most-reviewed product in the category, with more than 91,000 ratings, largely because it does far more than diaper duty. It is 41 percent petrolatum in a fragrance-free, preservative-free base that protects skin while still letting it breathe.
Parents use it as a diaper barrier, on drool rash, on dry and chapped skin, on minor scrapes, and on their own hands and lips. As a diaper ointment, it works the same way A+D does: a thin layer at each change keeps moisture off the skin. It is hypoallergenic, contains no fragrance, and comes from a pediatrician recommended brand.
Like A+D, it has no zinc oxide, so pair it with a paste when a rash flares. The 7-ounce tube is a better value than the small tubs, and it is the one product on this list that will keep getting used after diapers are done.
Best for: Families who want one multipurpose ointment for diaper area, drool rash, and dry skin.
Active ingredient: 41% petrolatum
Size: 7 oz tube
Price: About $11
Boudreaux's Butt Paste Maximum Strength
Boudreaux's Butt Paste Maximum Strength matches Desitin's 40 percent zinc oxide but in a formula many parents find easier to live with. It is creamier, spreads more smoothly, and wipes off more easily at the next change, with a milder scent.
The paste is hypoallergenic and free of dyes, parabens, preservatives, and talc. Boudreaux's has been a pediatrician-recommended brand for more than 40 years, and the Maximum Strength version has more than twice the zinc oxide of the brand's Original paste.
The choice between Boudreaux's and Desitin is mostly about texture. Desitin is thicker and stays put longer; Boudreaux's is smoother and less of a fight to apply and remove. Families who dislike the feel or smell of Desitin usually prefer this one.
Best for: Treating diaper rash with a maximum strength paste that is easier to apply and remove.
Active ingredient: 40% zinc oxide
Size: 4 oz tube
Price: About $9
How to Choose a Diaper Rash Cream
Ointment to prevent, paste to treat
Petrolatum ointments (A+D, Aquaphor) are thin, easy to apply, and ideal for prevention. Zinc oxide pastes (Desitin, Boudreaux's) are thicker and better at protecting skin that is already irritated. Many families keep one of each.
Zinc oxide percentage
Zinc oxide creams range from about 10 percent for daily use to 40 percent for maximum strength. Higher percentages form a thicker barrier and suit active rashes and overnight use.
Apply it thick and do not scrub it off
For an active rash, apply paste like frosting on a cake. At the next change, clean only the soiled skin and leave any clean paste in place, then add more on top. Scrubbing the barrier off irritates the skin again.
Frequently Asked Questions
Should diaper cream be used at every change?
It does not have to be, but a thin layer of ointment at each change helps prevent rash, especially for babies with sensitive skin, during teething or illness, and overnight.
When should a doctor look at a diaper rash?
Call the pediatrician if a rash does not improve after two to three days of treatment, if it has blisters, open sores, or pus, if it spreads beyond the diaper area, or if the baby has a fever. Bright red rashes with small spots around the edges can be yeast, which needs a different cream.
Can diaper cream be used with cloth diapers?
Petrolatum and zinc oxide creams can coat cloth diaper fibers and reduce absorbency. Use a disposable or fleece liner between the cream and the diaper, or choose a cream labeled cloth-diaper safe.
