Healing Nappy Rash: What to Know

Nappy rash, also called diaper dermatitis, often affects skin covered by the nappy. Irritation from moisture, stool, urine, rubbing, or a product can leave the skin red, sore, and tender. During healing, redness should become less intense, the skin should feel more comfortable, and raw areas should begin to close. Mild colour change can remain after the irritation has settled.

A rash that involves skin folds, has small separate spots around its edge, or does not improve with barrier care may have a fungal component. Other conditions can resemble nappy rash, so persistent or unusual changes deserve an examination rather than repeated self-treatment.

Change wet or soiled nappies promptly and clean gently with lukewarm water or a mild fragrance-free product. Pat the area dry, allow nappy-free time when practical, and fasten the nappy so it does not rub. Apply a protective, fragrance-free barrier layer to clean dry skin. Avoid talcum powder, fragranced wipes, harsh soaps, and scrubbing the sore area.

If irritation continues, a clinician may suggest an emollient routine to support the skin barrier. If the pattern suggests yeast or another fungal cause, a healthcare professional may recommend a topical antifungal treatment; use it only as directed and keep routine hygiene measures in place. See [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) and [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/).

Contact a healthcare professional if the rash is worsening, very painful, blistered, bleeding, weeping, or not settling despite careful nappy care. Prompt advice is needed for pus, spreading redness, marked swelling, fever, or a child who seems unusually sleepy, distressed, or unwell. A baby with a widespread rash or significant skin breakdown should be assessed without delay.

Ask what may be irritating the skin, which cleanser and barrier product to use, how often to apply it, and whether the rash could be fungal. Ask how long to try the plan, which signs suggest infection, and whether a prescribed treatment should be stopped or continued when the skin starts to improve.
