A+D vs Desitin is a question about two different jobs. A+D Original Ointment is a lanolin and petrolatum barrier that prevents diaper rash. Desitin Maximum Strength is a 40 percent zinc oxide paste that treats one that has already started. Parents buy one expecting it to do the other's job, and then wonder why the rash is not clearing or why the baby's bottom is permanently coated in thick white paste. Here is how they compare and when to use each.
Quick Verdict
Use A+D at every diaper change as a thin preventive layer, especially overnight and during teething or a round of antibiotics when rash is likely. Switch to Desitin Maximum Strength the moment skin turns red, apply it thick, and leave the clean paste in place at the next change rather than scrubbing it off. Once the rash is gone, go back to A+D. Most families should own both tubes.

How Each One Works
A+D forms a water-repellent film over the skin so urine and stool sit on the ointment instead of the skin. Lanolin adds a little moisturizing and healing. It is a prevention product: it keeps healthy skin healthy. Desitin's zinc oxide is a mild astringent and a physical barrier at the same time. It dries weepy skin, blocks moisture completely, and stays put through several changes. It is for skin that is already irritated.
When to Use A+D
Every change, in a thin layer, as routine. Thicker before bedtime when the diaper is on longest. During teething, after antibiotics, and when starting new foods, when stool gets more acidic and rash shows up fast. A+D also works on drool rash around the mouth and on chapped cheeks in winter.
When to Use Desitin
At the first sign of pink or red skin. Apply a thick layer, like frosting a cake, and do not wipe it all off at the next change. Clean the soiled part, pat dry, and add more on top. If the rash has not improved in two to three days, or if you see bright red spots with defined edges, small pimples, or blisters, it may be yeast and needs a pediatrician and an antifungal, not more zinc.
Cost and Mess
A+D is far cheaper per ounce and comes in a big tub that lasts months. Desitin Maximum Strength costs more and a tube goes fast when you apply it properly thick. Desitin also stains cloth diapers and clothing; A+D washes out. For cloth diaper families, A+D with a liner is the daily choice and Desitin only when needed.

Frequently Asked Questions
Is there a zinc oxide version of A+D?
Yes. A+D Zinc Oxide Cream has 10 percent zinc and sits between the Original ointment and Desitin in strength. It is a mild treatment, not a maximum-strength one.
Can I mix A+D and Desitin?
You can layer them, zinc first and ointment over it, but there is little reason to. Use one or the other depending on whether skin is healthy or irritated.
Which is safe with cloth diapers?
A+D with a disposable liner. Desitin's zinc can build up in cloth and cause repelling. Use a liner or switch to disposables during a Desitin course.
