Yeast vs Irritant Nappy Rash: How to Tell | Parenting Hub
Most nappy rashes are irritant and clear with barrier cream. Yeast rashes look different and need an antifungal — here's how to tell.
Most nappy rashes are caused by wet skin and clear quickly. A yeast (candida) rash looks different and needs antifungal cream — knowing which is which saves days.
Irritant nappy rash (most common)
- Red, sore patches on the parts touching the nappy
- Spares the skin creases
- Clears in a few days with frequent changes, gentle cleaning and barrier cream (zinc, paw paw)
Yeast (candida) nappy rash
- Bright beefy-red
- INVOLVES the skin creases (groin, inner thighs)
- Small red 'satellite' spots around the main patch
- Doesn't improve — or gets worse — with barrier cream alone
Treatment
Yeast rashes need an antifungal cream (e.g. clotrimazole or nystatin from your pharmacist). Apply 2–3 times a day under a thin layer of barrier cream. If baby has oral thrush as well, treat both at once.
What helps both kinds
- Change nappies as soon as wet/dirty
- Wash gently with warm water and pat dry (no wipes with fragrance/alcohol)
- Nappy-free time several times a day
- Thick barrier cream at every change
When to seek help
- Rash not improving after 5–7 days of treatment
- Spreading redness, weeping, blisters or pus
- Fever or unsettled baby alongside the rash
- Cracked, bleeding skin
Common questions
Can I use hydrocortisone?
Only on GP/pharmacist advice for short courses. Steroid creams on undiagnosed yeast rash can make it worse.
