How to Prevent and Treat Adult Diaper Rash

Incontinence-associated dermatitis (IAD), commonly known as adult diaper rash, is a very common skin inflammation that affects people who use adult diapers or absorbent pads. Characterized by redness, burning, itching and, in more severe cases, skin sores, this condition can cause significant discomfort.

Fortunately, with the right daily skincare routine and appropriate products, it is entirely possible to prevent and treat this condition, helping restore comfort, well-being, and dignity to people living with incontinence.

In this practical guide, we’ll explain step by step how to protect the skin of adults and older adults.

What Causes Adult Diaper Rash?

Contrary to what many people believe, diaper rash is not caused by the diaper itself, but rather by prolonged exposure of the skin to moisture and acidic substances found in urine and stool.

The skin barrier of adults (especially older adults) is thinner and more sensitive. When continuously exposed to moisture, the skin undergoes a process of maceration (becoming overhydrated), creating the ideal environment for the growth of fungi and bacteria.

How to Prevent Diaper Rash (Daily Care Tips)

Prevention is always the best treatment. To keep the skin healthy and free from diaper rash, follow these three golden rules:

1. Change diapers frequently

Don’t wait until the diaper or absorbent pad reaches its maximum absorbency. The rule is simple: whenever there is urine or stool, change the diaper immediately. For nighttime use, choose high-absorbency products, such as our Intimus Premium Care Maxi Adult Diapers, to help keep the skin dry for longer.

2. Choose diapers with active skin protection and vitamin E

Choosing the right diaper makes all the difference in preventing diaper rash. Today, it’s not enough to simply keep moisture away; you also need to support the skin’s natural barrier. Intimus Premium Care Adult Diapers go a step further in prevention: they contain a special lotion enriched with vitamin E.

Vitamin E acts as a powerful antioxidant and moisturizer that works directly on the skin while the diaper is being worn, helping strengthen its natural defense against irritation caused by urine and stool.

3. Gentle cleansing (Say “no” to regular soap)

Frequent washing with water and regular soap can dry out the skin even further.

Instead of unnecessary full-body washing, use adult wet wipes, such as Intimus XL Wipes.

Important note: Avoid using baby wipes, as they are not formulated with the appropriate pH for mature adult skin. Choose Intimus XL Wipes, specially developed for mature skin, to cleanse, moisturize, and protect in a single step.

How to Treat Diaper Rash Once It Has Developed

If the skin is already red, irritated, or showing small cracks, it’s important to act quickly to prevent the condition from progressing to a fungal infection (such as candidiasis).

Clean the area gently: When cleaning the affected area, avoid rubbing. Use adult wet wipes gently, patting the skin instead.
Dry the skin thoroughly: Before putting on a clean diaper, make sure the skin is completely dry. If possible, allow the skin to air dry for a few minutes, using an absorbent bed pad to protect the mattress.
Take advantage of continuous skin hydration: When using an Intimus Premium Care Adult Diaper, the vitamin E-enriched lotion helps soothe irritated skin and supports the skin’s natural recovery process.
Avoid fastening the diaper too tightly: Make sure the diaper fits securely enough to prevent leaks, while still allowing air to circulate.

When Should You See a Doctor?

Although most cases improve within 2 to 3 days with proper care, you should consult a healthcare professional if you notice:

Blisters or open sores.
Pus or bleeding.
Fever or severe pain in the affected area.
No improvement after several days of treatment.
