Nappy rash that is red and raw: what to know

Redness often follows the areas that stay damp or rub against the nappy. Rawness means the surface has become especially irritated and may feel sore during cleaning. A rash caused mainly by contact often affects the raised, rubbing surfaces while sparing deeper folds. Yeast can involve the folds and may show small spots beyond the main red area. Colour can be harder to judge on darker skin, so warmth, swelling, tenderness, texture and behaviour are also useful clues.

Change wet or soiled nappies quickly. Clean with lukewarm water and a soft cloth, then pat dry without rubbing. Let the skin air briefly and apply a fragrance-free protective barrier in a thick layer. Use loose nappies and clothing, and pause any new wipes, creams or detergents until the skin settles. If the rash stays vivid in the folds or develops edge spots, a clinician can assess whether [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) or [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) is suitable.

Arrange medical advice if redness is spreading, raw areas are worsening, the rash keeps returning or there is no improvement with careful nappy care. Seek prompt help for fever, marked pain, warmth, swelling, pus, blisters, bleeding, poor feeding or unusual sleepiness. Do not rely on colour alone to judge severity, and do not use prescription creams without specific instructions.

Does the pattern fit irritation, yeast or another diagnosis? Which barrier is appropriate for raw skin? Should I change wipes or washing products? What symptoms require same-day assessment?
