Eczema treatment: calm a flare and rebuild your skin barrier

Eczema (atopic dermatitis) is a skin barrier problem and an immune problem at the same time. That is why moisturizer alone is sometimes not enough, and why steroid creams alone do not make it go away for good. The good news: with the right routine, most people can keep it well controlled.

Quick answer: Moisturize your whole body at least twice a day with a thick, fragrance-free cream or ointment, even when your skin looks fine. Treat flares early with an anti-inflammatory cream: mild hydrocortisone from a pharmacy for small patches, stronger creams from a doctor. Avoid your triggers. See a doctor if a flare does not settle within a week, if you see signs of infection, or if itching ruins your sleep.

What is eczema?

Eczema is a long-term condition that makes skin dry, itchy and inflamed. It often starts in childhood and may improve with age, but many adults have it too. It is not contagious. It tends to come and go in flares, with calmer periods in between. On lighter skin, flares look red; on brown and Black skin, they may look dark brown, purple or grey, and can leave lighter or darker patches after they heal.

It is more common if a parent has eczema, or if you or a close relative has asthma or hay fever.

What is going on in the skin?

• A leaky barrier. Many people with eczema make less of some proteins and fats that seal the skin. Water escapes and irritants get in more easily.
• An overreactive immune response. The skin reacts with inflammation and intense itch.
• The itch-scratch cycle. Scratching damages the barrier further, which makes the itch worse, which leads to more scratching.

Common triggers

• Soap, bubble bath and strong foaming cleansers.
• Fragrance in skin care, laundry products and air fresheners.
• Wool and rough or tight fabrics.
• Sweat and heat, or cold, dry air.
• Stress.
• Dust mites, pet dander and pollen.
• Skin infections.
• Hormonal changes, such as around periods or in pregnancy.
• Certain foods, mostly in babies and young children, and only when confirmed by a doctor.

The daily routine that helps prevent flares

1. Short, warm (not hot) showers or baths, about 5–10 minutes. Long, hot water dries skin out.
2. Use a gentle, soap-free cleanser or wash with an emollient (a moisturizer used as a soap substitute), only where needed.
3. "Soak and seal": pat the skin until it is just damp, then apply moisturizer within 3 minutes of getting out of the water.
4. Moisturize at least twice a day, generously, all over, even on good days. A large tub should run out in weeks, not months.
5. Use a pump or a clean spoon to take moisturizer out of a tub, so you do not add germs.
6. Wash clothes with fragrance-free detergent, wear soft cotton and keep nails short.

Which moisturizer is best?

Helpful ingredients include ceramides, which are fats found naturally in the skin barrier, glycerin, colloidal oatmeal and urea. Urea can help with thick, rough patches but may sting on broken skin. Occlusives, ingredients that form a seal on top of skin, help most when skin is very dry.

Choose fragrance-free products. Fragrance and essential oils can irritate or cause allergic reactions, and eczema skin is more likely to react. Patch test any new product on a small area first.

Treating a flare

Moisturizer helps prevent flares, but it does not calm active inflammation on its own. Treat flares early.

Over-the-counter options

• Mild hydrocortisone cream is sold in pharmacies in many countries for small, mild patches on the body. Follow the label, and ask a pharmacist or doctor before using it on the face, on children or for more than about a week.
• Colloidal oatmeal baths or creams can ease itch.
• Cool compresses can calm itch for a while.

Prescription treatments

A doctor can prescribe:

• Topical corticosteroids in different strengths. Used as directed, for the right length of time, they are safe and effective. Using too little or stopping too early often makes flares last longer.
• Non-steroid creams and ointments, such as calcineurin inhibitors, PDE4 inhibitors and topical JAK inhibitors. These are often used on the face, eyelids and skin folds.
• Wet wraps, a damp layer of clothing or bandage over moisturizer or medicine, then a dry layer, for very itchy flares. Ask your doctor how to do this safely.
• Bleach baths in specific amounts, sometimes advised for people who get frequent skin infections. Only do this on a doctor's instructions.

For moderate to severe eczema

When creams are not enough, a dermatologist may suggest light therapy (phototherapy), tablets that calm the immune system, or newer medicines such as biologic injections and oral JAK inhibitors. These can work very well, but they need a specialist to weigh the benefits and side effects and to monitor you. Talk to your doctor about what fits your situation.

What not to put on eczema skin

• Fragrance, essential oils, menthol and alcohol-heavy products.
• Retinoids, exfoliating acids and scrubs on active patches.
• Steroid creams on the face for long periods without a doctor's plan. This can thin the skin or trigger other rashes.
• Olive oil as your only moisturizer. A small study found it weakened the skin barrier in adults. Sunflower seed oil and petrolatum are gentler choices.
• Aqueous cream (in countries where it is sold) as a leave-on moisturizer, as it can irritate eczema skin.

Eczema on the face, hands and eyelids

Some areas need a little extra care:

• Face and eyelids. The skin here is thin and absorbs creams easily. Use only gentle, fragrance-free products, and ask a doctor which anti-inflammatory cream is suitable. Doctors often choose non-steroid creams for eyelids.
• Hands. Frequent washing and hand sanitizer can trigger flares. Wash with lukewarm water and a mild cleanser, then moisturize every time. Wear cotton-lined gloves for wet work and cleaning. If hand eczema keeps coming back, ask about patch testing, which checks for allergies to things you touch.
• Skin folds (inner elbows, behind the knees, neck). Sweat and friction make these areas flare. Loose, breathable clothes help.
• Scalp. Eczema can cause an itchy, flaky scalp. Choose fragrance-free shampoos and see a doctor if it does not settle.

How long until results?

Itch often eases within days of starting the right anti-inflammatory treatment. A good barrier routine usually takes a few weeks to reduce how often flares happen. Eczema is long term: the goal is control, so that flares are fewer, shorter and milder.

Living with eczema

• Keep a simple diary of flares and possible triggers.
• Carry a small tube of moisturizer for hands, especially after washing.
• Keep your bedroom cool and use breathable bedding.
• Stress can trigger flares. Sleep, exercise and support from others help.
• Eczema can affect mood and sleep. Talking to your doctor about this is part of treatment.

When to see a doctor (today)

Get urgent medical help if you notice:

• Yellow crusts, pus-filled spots, weeping or rapidly spreading redness, or skin that is hot, swollen and painful. These can be signs of infection.
• Painful clusters of small blisters or punched-out sores, especially with a fever or feeling unwell. This can be eczema herpeticum, a serious infection that needs treatment right away.

Book a regular appointment if:

• A flare does not improve after a week of treatment.
• Itching keeps you or your child awake at night.
• You need steroid creams very often.
• Eczema is affecting your mood, school, work or relationships.
• You are not sure whether it is eczema, or a rash looks different from usual.

FAQ

Is eczema contagious?

No. Eczema itself cannot be caught. Infected eczema can spread germs, so keep infected skin covered and see a doctor.

Should I stop eating dairy or gluten?

Not without testing and a doctor's advice. Unnecessary diets rarely help adults and can cause nutrition problems, especially in children.

Can I wear sunscreen with eczema?

Yes. Many people with eczema tolerate mineral sunscreens with zinc oxide or titanium dioxide well. Patch test first.

Are steroid creams safe?

Used as your doctor directs, for the right length of time and on the right areas, they are safe and very effective. Ask your doctor or pharmacist how much to use and for how long.

Will my child grow out of eczema?

Many children improve as they get older, but some keep having eczema into adulthood. Good skin care helps at every age.
