Gentle skin care and pharmacy advice may suit minor irritation, eczema or insect bites. Monitor for spread, pain, fever or reduced wellbeing.
View NHS rash guidanceMany childhood rashes are mild, but the child's breathing, alertness, temperature and hydration determine urgency. Good photographs can help, yet an unwell child may need immediate examination.
Rashes and colour changes can look different across skin tones. Check palms, soles, lips, tongue and inside the eyelids when pallor, blue-grey colour or blotchiness is a concern.

A well child with a mild local rash can often start with pharmacy advice; fever, rapid spread or systemic illness needs clinical review.

Explore in-person GP careUse 999 for a non-fading rash with illness, breathing or swelling signs. Use 111 for fever, rapidly changing rash, poor feeding or dehydration.
Contact NHS 111Do the glass test only when safe and do not let a fading rash falsely reassure you if the child is seriously unwell.
Distribution, texture and associated symptoms are more useful than colour alone.
A non-fading bruise-like rash in an unwell child is an emergency; press a clear glass firmly if you are unsure.
Hives, eczema, bites and contact reactions can itch, but mouth swelling or breathing difficulty indicates anaphylaxis.
Blistering, weeping, honey-coloured crusts or rapidly spreading painful skin may indicate infection.
The child's age, vaccination history, illness contacts, breathing, feeding and overall behaviour guide urgency.
Measles is highly infectious. If you suspect it, call the GP or NHS 111 before attending in person so the service can reduce exposure to others.
A clinician can review the pattern and general health, but children who are unwell or whose diagnosis is unclear may need face-to-face care.
Explore in-person GP careDiscuss where it began, spread, texture, itch, pain, blisters, crusting, blanching and how long it has been present.
Cover fever, breathing, alertness, feeding, hydration, sore throat, joint pain, medicines, vaccinations and illness contacts.
An in-person skin and general examination, swab or other test may be needed for infection, blistering or uncertainty.
Different rashes need very different care. Avoid starting strong or leftover treatments before the likely cause is clear.
Use fragrance-free products and avoid new irritants. A pharmacist can advise on moisturisers and suitable itch relief.
Some rashes spread easily. Handwashing, separate towels and school or nursery advice depend on the diagnosis.
A clinician may advise antifungal, antibiotic, antiviral, steroid or other treatment only when the assessment supports it.
Do not apply someone else's prescription or strong steroid to a child's rash. Treatment strength, site and duration matter, especially on the face and skin folds.
Photograph the rash in natural light: one wider image showing location and one close image showing texture. Include a ruler or coin for scale if useful.
Note the child's age, fever, behaviour, breathing, feeding, urine, itch or pain, new products or medicines, illness contacts, vaccination status and when the rash began.

Press the side of a clear glass firmly against the rash. If an unwell child's rash does not fade, call 999 or go to A&E.
Good photos and video can help, especially if the child is well. An in-person assessment is safer when the child is unwell, the rash is painful or blistering, or the diagnosis is unclear.
Redness may be less obvious. Texture, heat, swelling and pain matter, and colour changes may be easier to see on palms, soles, lips, tongue and inside the eyelids.
Seek urgent advice and call before attending a clinic because measles spreads easily. Mention vaccination status and any known exposure.
