What should you do if your baby has diaper rash? What are the recommended products to prevent and treat it? You are not the only parents with these questions: more than 50% of babies will be affected.

Focussing on solutions, this article about diaper rash was prepared in collaboration with Marie Fortier, a nurse who specializes in pre- and post-natal care.

What are the causes of diaper rash?

As is the case with other skin conditions, many factors may be considered:

  • Humidity of the diaper area;
  • Exposure to irritants present in urine and faeces;
  • Friction (diaper and skin folds);
  • Presence of chemical components in diapers, wipes and creams;
  • Seborrheic dermatitis that might already be present.

How to prevent and get rid of diaper rash?

Always make sure to use products that:

  • Are clinically approved and specifically made for babies
  • Are hypoallergenic
  • Don’t contain any perfume, coloring, alcohol or other substances that may irritate the eyes and skin


  • ✅ After the bath, moisturize your baby’s bottom with a hypoallergenic cream in order to keep the skin barrier intact.

We recommend: Cutibase, Cerave, Exomega, Uriage, Glaxal-Base.

  • ✅ Change diapers often to prevent humidity and minimise the contact of the skin with urine and faeces.
  • ✅ When changing diapers, do not overwash. For instance, when there is only a little pee, we’ll prefer to simply wipe with a clean damp cloth.
  • ✅ Avoid commercial wipes.



  • ✅ For disposable diapers, test by switching brands: your baby may react to certain components contained in one brand of diapers and not in others.
  • ✅ Dry the diaper area and apply a thick cream or paste that will act as a protective barrier.

We recommend Zinc paste, Ihle’s paste or Vaseline.

  • ✅ Leave baby’s bum diaper free for short periods throughout the day.


  • ✅ Consult with a family doctor or dermatologist who can prescribe a low-dose cortisone cream (to be applied 2x/day until symptoms go away).
  • ✅ Cortisone cream is very efficient when the diaper rash is persistent or recurrent. In these cases, it is better to apply cream on a small area as soon as rough red patches appear rather than wait too long and then have a bigger area to treat.
