Eczema Flare-Ups: What Causes Them and How to Stop Them
FAST ANSWER
Eczema flare-ups happen when the skin becomes irritated due to triggers such as dry skin, harsh products, stress, or weather changes. Managing flare-ups involves avoiding triggers, keeping the skin hydrated, and using gentle, barrier-supporting treatments consistently.
Eczema flare-ups can feel sudden and frustrating.
Your skin may be calm for a period of time, and then symptoms return quickly with redness, itching, and irritation.
Understanding what causes flare-ups and how to manage them is key to keeping your skin under control.

What Is an Eczema Flare-Up?
A flare-up is a period when eczema symptoms become worse.
During a flare-up, you may notice:
• Increased itching
• Red or inflamed skin
• Dryness and rough texture
• Cracking or irritation
To understand symptoms more broadly, see eczema symptoms and early signs.
Many people also find that their symptoms peak during rest, and understanding why eczema gets worse at night can help you manage these acute phases more effectively. To understand symptoms more broadly, see eczema symptoms and early signs.
What Causes Eczema Flare-Ups?
Flare-ups are often influenced by your body's natural rhythms. Many patients find that their skin feels relatively calm during the day only to flare up before bed, which is why learning why eczema gets worse at night is essential for planning your evening skincare.
Flare-ups are usually triggered by external or internal factors.
1. Dry Skin
When the skin loses moisture:
• It becomes fragile
• Irritation increases
• Symptoms worsen
2. Irritants
Common irritants include:
• Harsh soaps
• Fragrance
• Cleaning products
3. Weather Changes
Cold, dry air and wind can weaken the skin barrier.
Heat and sweating can also trigger irritation.
4. Stress
Stress can increase inflammation and make the skin more reactive.
If stress seems to worsen your skin, our guide to can stress trigger eczema flare-ups explains how stress affects itching, inflammation, and flare-up severity.
5. Allergens
Triggers such as dust, pollen, and pet dander can worsen symptoms.
To explore triggers in more detail, see eczema triggers and how to avoid them.
Eczema flare-ups can sometimes be more noticeable in specific areas of the body. For example, flare-ups on the face may be linked to environmental exposure or skincare products, while flare-ups on the hands may involve irritation or small blisters.

How Flare-Ups Relate to Causes
It is important to understand the difference:
• Causes make your skin prone to eczema
• Triggers cause flare-ups

How to Stop an Eczema Flare-Up
Managing flare-ups requires a simple, consistent approach.
1. Hydrate the Skin
Apply a moisturiser regularly to reduce dryness and irritation.
2. Avoid Triggers
Identify what worsens your symptoms and reduce exposure.
3. Use Gentle Skincare
Choose fragrance-free and non-irritating products.
4. Use Targeted Treatment
A suitable eczema cream can help:
• Calm inflammation
• Reduce itching
• Support skin repair
To understand treatment in more detail, see eczema treatment and long-term care.
What to Do During a Flare-Up
When symptoms worsen:
• Keep your routine simple
• Avoid introducing new products
• Moisturise more frequently
• Reduce exposure to irritants
It is crucial to act quickly to stop the itch-scratch cycle, as the more you scratch during a flare-up, the more inflammation you trigger, which only prolongs the healing process.
For practical steps during an active flare-up, see our guide to how to calm eczema flare-ups fast.
Consistency is key.

Preventing Future Flare-Ups
Preventing flare-ups is just as important as treating them.
Focus on:
• Daily hydration
• Gentle skincare
• Avoiding known triggers
• Supporting the skin barrier
Building a resilient barrier is a gradual process. Many people wonder how long does skin barrier repair take after a particularly bad flare-up; while redness may fade in days, deep structural recovery often takes several weeks of consistent protection and hydration.
Learning how to repair your skin barrier naturally by prioritizing non-irritating moisture and protection can help prevent the cycle of chronic inflammation from restarting.
Supporting Your Skin
Even when symptoms improve, ongoing care is essential.
A gentle option like our Atopic Cream can help:
• Soothe irritation
• Hydrate dry skin
• Support long-term skin repair

• Flare-ups become severe
• Skin becomes painful or infected
• Symptoms do not improve
Final Thoughts

• Maintain healthier skin over time
