Myth: "Eczema is caused by dirt"

Doctor review pending

Eczema is a barrier and immune condition — over-washing makes it worse.

Key points

  • Eczema isn't caused by dirt.

The myth


Some think a child with eczema is not being washed enough.

The facts: how it really works


Eczema is linked to inherited differences in the skin barrier (such as filaggrin) and an overactive immune response. Soap and frequent hot bathing strip natural oils and worsen it.

Why it matters on darker skin


On dark skin eczema looks brown, grey or purple and often appears as bumps around hair follicles.

Where the myth comes from


Rough, dry patches can look dirty; stigma persists.

What actually helps — and why


Emollient twice daily: barrier repair. Expected timeline: days. Soap substitute: protects oils. Expected timeline: immediate.

More detail


Children with eczema are sometimes teased, or parents are blamed, because rough, dark or scaly patches are mistaken for dirt. Eczema runs in families and is closely linked with asthma and hay fever. Many children have inherited differences in proteins such as filaggrin that help hold the skin barrier together, so water escapes and irritants get in. The immune system then reacts more strongly than usual, which causes the itch. Scratching damages the barrier further and leads to thickened, darker skin, which can look 'unwashed' but is not. Washing more often, especially with soap, antiseptic or hot water, removes the skin's natural fats and makes eczema worse. The best routine is a short, lukewarm bath with a soap substitute, patting dry and applying emollient straight afterwards — plus prescribed treatments for flares. Schools should understand that eczema is not catching.

What to avoid and why


Avoid antiseptics, perfumed soaps and scrubbing.

Common mistakes


  • Blaming the parent.

Caring for children's skin


Children's skin is thinner, loses water faster and absorbs more of what is applied to it relative to body size, so simpler is safer. For most children a short lukewarm bath, a fragrance-free soap substitute and a plain emollient are all that is needed, plus shade, clothing and sunscreen from six months of age. Avoid adult products, essential oils, antiseptics in bath water, bleaching or 'toning' creams, and cosmetic treatments such as relaxers and gel nails. Medicines and medicated creams should be used only as a doctor, nurse or pharmacist advises, and in children Melanin & Me does not offer photo checks: a clinician should see the child. Trust your instincts as a parent: a child who is unusually sleepy, floppy, not feeding, breathing fast or has a rash that does not fade when pressed with a glass needs urgent care. Keep a simple record — photos and dates — of rashes that come and go, as this helps the doctor.

Products, medicines and when to worry


When choosing products for children, look for fragrance-free formulas with short ingredient lists, and avoid adult acne, anti-ageing or lightening products, essential oils and talc. Medicated creams — including steroid creams, antifungals and antibiotics — are safe and helpful when prescribed for the right condition and used for the right length of time, but mixed creams sold over the counter can contain strong steroids that are unsafe for children. Sunscreen is suitable from six months of age; younger babies should be kept in the shade and covered. Do not give medicines intended for adults, and ask a pharmacist about the right medicine for a child's age and weight. Seek urgent care for any rash with fever and a very unwell child, a rash that does not fade under a glass, swelling of the face or lips, or blistering of the mouth or eyes.

Important

When to see a doctor

See a doctor if eczema keeps the child awake or looks infected.

Visit a hospital or clinic near you and ask to see a dermatologist (skin specialist), or ask your general doctor for a referral. Take this page and the products you use with you. Emergency: call 112.

Questions to ask your doctor or pharmacist


Useful questions include: What do you think is causing this? Is it likely to come back, and how can I prevent it? Which products should I stop? How long before I should expect improvement, and when should I come back if it isn't better? Are there side effects to watch for? Is this treatment safe if I am pregnant, breastfeeding or for my child? Writing your questions down, bringing your products (or photos of their labels) and taking dated photos of the problem make an appointment much more useful.
