Everything you need to
know about nappy rash
Here at Metanium we have been treating and protecting babies’ bums for over 30 years. We understand that nappy rash is a cause of concern for parents. We also know that your little one will most likely experience nappy rash at some point before they are toilet trained. So if you want to find out what causes nappy rash, how to protect your little one from the symptoms and what you can do to minimise the frequency of nappy rash developing, read on to find out more. That’s one more worry you can tick off your list!

What causes nappy rash?
Nappy rash is most common in 9-12 month old babies, but all babies in nappies can develop it, so it’s always best to be prepared! Nappy rash can be caused by:
- Your baby's skin being in contact with wee or poo (stools) for a long time.
- The nappy rubbing against your baby's skin.
- Not cleaning the nappy area or changing the nappy often enough.
- Using irritable or fragranced soaps, detergent or bubble bath.
- Using alcohol-based baby wipes.
- Your baby recently taking antibiotics.

Symptoms of nappy rash
- Inflamed skin - the skin around your baby's genital and anus area may look red and tender.
- Blistering – the skin may blister and then peel, leaving raw patches (ulcers).
- Spreading – the rash can spread onto the tummy and buttocks.
- Ulcers – small ulcers can sometimes form on healthy skin, near the area of the rash.
- Damage to the skin is sore and can unsettle the baby, especially when urine comes into contact with the rash.


A barrier ointment used on your baby’s skin at every nappy change can form part of a healthy skincare routine. Metanium’s Everyday Barrier Ointment has been specifically formulated to prevent and protect your baby from nappy rash.


Always seek medical advice from your pharmacist, your health visitor or GP if:
- Your baby's nappy rash is spreading or getting worse.
- Your little one develops a persistent, bright red, moist rash with white or red pimples that spreads into the folds of their skin.
