What Causes Diaper Rashes To Get Worse?

Quick answer: Contact with wet or soiled diapers, rubbing and irritating products can worsen diaper rash. Infection or another skin condition may need medical care. The earlier skin-mechanism and equipment explanations on this page were not supported and have been removed.

What Causes Diaper Rashes To Get Worse?

Start with the irritants you can identify

Check when the rash started, how often the diaper is changed, and whether a new wipe, cleanser, diaper or cream was introduced. Do not assume that every red rash has the same cause.

Cream advice: the product matters

Barrier care should not be confused with adding multiple medicated products. The AAP diaper-rash guidance discusses zinc oxide or petrolatum barriers, while NHS nappy-rash guidance advises following appropriate cream advice. Use the product instructions or your clinician’s directions; avoid treating “too much cream” as a universal cause of worsening rash.

Do not scrub off clean barrier paste just to expose the skin. Ask a pharmacist or clinician about products that sting, fragrance sensitivity, or a rash that worsens after application. Do not add steroid, antifungal or antibiotic treatments without appropriate advice.

  • ☐ Change a wet or soiled diaper promptly.
  • ☐ Clean gently; avoid unnecessary rubbing and fragranced products.
  • ☐ Use suitable barrier care according to the label or professional advice.
  • ☐ Check for tightness and friction.
  • ☐ Record new products and changes in the rash so you can explain them clearly.

When to seek medical advice

Contact your child’s clinician if the rash is worsening or not improving after a few days, or if there is fever, marked pain, blisters, pus, oozing or other signs of illness. A clinician can distinguish irritation from infection and other conditions.
