Managing a flare-up of atopic eczema or psoriasis at home requires a structured clinical approach that focuses on two goals: calming the immediate inflammation and restoring the skin’s protective barrier. In the UK, healthcare providers recommend a step-up strategy where you increase the intensity of your skin care routine the moment you notice the first signs of redness or itching. By acting quickly and using your prescribed treatments correctly, you can often prevent a minor flare-up from becoming a severe or infected episode that requires urgent medical intervention.
What We’ll Discuss in This Article
- Identifying the earliest signs of a skin flare-up.
- The correct step-up use of emollients and soap substitutes.
- Safe application of topical steroids using the fingertip unit.
- Managing the itch-scratch cycle with cooling techniques.
- When to transition from home care to a GP consultation.
- Home safety tips to prevent secondary infections.
1. Step up your emollient routine
The foundation of home treatment is a significant increase in the frequency of emollient (moisturiser) application. During a flare-up, the skin barrier is physically compromised, allowing moisture to evaporate rapidly.
- Increase Frequency: Apply your emollient every 2 to 3 hours, or as soon as the skin feels dry or tight.
- Liberal Application: Use large amounts of product. For an adult with a widespread flare, you may need up to 500g of emollient per week.
- Soap Substitutes: Ensure you are not using any traditional soaps or bubble baths, which strip away natural oils. Use your emollient or a specialised wash-off cream to cleanse the skin in lukewarm water.
2. Apply topical steroids correctly
If you have been prescribed a medicated cream, such as a topical corticosteroid, you should begin using it as soon as the skin becomes red and inflamed.
- The Fingertip Unit (FTU): Use the FTU method to ensure you are applying the correct dose. One FTU is the amount of cream squeezed from a standard tube onto the end of an adult’s index finger, which is enough to cover an area of skin the size of two adult palms.
- Thin Layer: Apply the steroid thinly only to the affected, red areas.
- Timing: Apply your emollient first, wait 20 to 30 minutes for it to absorb, and then apply the steroid. This prevents the medication from being diluted or blocked.
3. Manage the itch without scratching
Scratching is the primary cause of skin damage and infection during a flare-up. To break the cycle at home:
- Cooling the Skin: Use a cold compress or a damp, cool cloth on the itchy area for 5 to 10 minutes. This can distract the nerves and reduce the urge to scratch.
- Keep Creams Cool: Some people find that keeping their emollients in the fridge makes them more soothing when applied to angry skin.
- Cotton Clothing: Wear loose, 100% cotton clothing to allow the skin to breathe and reduce friction. Avoid wool or synthetic fabrics, which can trap heat and worsen the itch.
4. Identify and remove triggers
A flare-up is often the body’s reaction to a specific trigger. Take a moment to review if you have recently been exposed to:
- New Products: Laundry detergents, fabric softeners, or new perfumes/soaps.
- Environmental Factors: Dust mites (often disturbed during cleaning), pet dander, or sudden changes in temperature and humidity.
- Stress: High periods of emotional pressure can trigger a biological flare.
5. Identifying the signs of infection
While managing at home, you must monitor the skin for signs that the flare-up has become infected. Home care is not enough if:
- The skin is weeping a clear or yellow fluid.
- Small, pus-filled blisters (pustules) appear.
- You notice golden or honey-coloured crusts on the surface.
- The skin becomes increasingly painful, hot, or swollen.
- You develop a fever or feel generally unwell.
If you see any of these signs, you must contact your GP or call 111, as you may require antibiotics to resolve the infection.
Conclusion
Treating a skin flare-up at home is about providing your skin with the stable, hydrated environment it needs to heal. By acting at the first sign of redness, increasing your emollient use, and applying medicated creams as prescribed, you can often regain control of your symptoms within a few days. Consistency and the avoidance of harsh irritants are the most powerful tools you have to maintain your skin health and prevent complications.
Can I use cold compresses to stop the itch?
Yes, a clean, damp, cool cloth applied to the area for 5 to 10 minutes helps soothe the skin and distracts nerves from the itch reflex.
How much steroid cream should I apply?
Use the fingertip unit method. One unit is the amount squeezed onto the fingertip, covering an area equal to two adult palms. Apply only a thin layer.
Should I apply my emollient before or after my steroid?
Apply your emollient first, then wait 20 to 30 minutes for it to fully absorb before applying the medicated cream to ensure the steroid is not diluted.
What are the signs of an infected flare-up?
Look for weeping fluid, golden or honey-coloured crusting, small pus-filled blisters, or skin that is becoming increasingly hot, swollen, or painful.
Can stress trigger a skin flare-up?
Yes, intense emotional pressure is a well-known biological trigger that can cause or worsen eczema and psoriasis flare-ups even when you are managing your skin.
When should I stop home care and see a doctor?
Stop self-treatment and contact your GP if you notice signs of infection, if the condition spreads rapidly, or if your symptoms do not improve after four weeks of care.
