Eczema Triggers: What Causes Flare-Ups and How to Avoid Them
FAST ANSWER
Eczema triggers are factors that cause flare-ups by irritating the skin or weakening the skin barrier. Common triggers include dry skin, harsh skincare products, weather changes, stress, and allergens. Identifying and avoiding your personal triggers is key to reducing flare-ups and keeping skin calm.
Eczema flare-ups can feel unpredictable. However, in most cases, they are linked to specific triggers that irritate the skin or disrupt its natural barrier. This process is especially common for those with sensitive skin, as a compromised outer layer allows environmental stressors to trigger inflammation much faster than they would on healthy skin.
If you understand what is causing your flare-ups, you can take simple steps to reduce them and calm eczema flare-ups faster when symptoms appear.

What Are Eczema Triggers?
Eczema triggers are external or internal factors that make eczema symptoms worse.
They do not cause eczema itself, as the underlying causes of eczema are linked to genetics, immune response, and skin barrier dysfunction.
• Increase inflammation
• Dry out the skin
• Make itching more intense
• Lead to flare-ups
Ongoing inflammation and scratching during flare-ups may also cause symptoms to affect larger areas of skin over time. We explain this further in why eczema rash spreads during flare-ups.
Because eczema-prone skin already has a weakened barrier, it reacts more easily than normal skin.
These underlying causes often contribute to recurring eczema flare-ups, especially when the skin barrier becomes weakened or irritated.
Eczema Triggers Can Affect Different Areas of the Body
Facial eczema is often particularly sensitive to triggers such as weather changes, fragranced skincare products, harsh cleansers, and environmental irritation. Areas such as the nose, mouth, cheeks, and chin may react differently during flare-ups. You can explore these areas further in our guide to facial eczema by location.
Eczema triggers can affect people in different ways. For some people, flare-ups appear on the face. For others, they may affect the eyelids, hands, feet, or a baby’s sensitive skin.
Some triggers are even more localized; for example, friction from glasses or hair product residue can lead to persistent Eczema Behind the Ears, making it important to identify exactly where your skin is reacting.
If your symptoms appear in a specific area, these guides may help:
• Facial eczema
• Eyelid eczema
• Infant eczema

Common Eczema Triggers
1. Dry Skin
Dry skin is one of the most common triggers.
When the skin loses moisture:
- It becomes tight and fragile
- Cracks can develop
- Irritation increases
In some cases, irritation and moisture can lead to small fluid-filled bumps on the skin, particularly on the hands. Our guide on small blisters on hands explains what causes this and how to manage it.
Keeping the skin hydrated is essential for preventing flare-ups.
Triggers often lead to visible skin changes. Learn more about eczema rash and how to treat it.
2. Harsh Skincare Products
Many everyday products can irritate eczema-prone skin.
Common irritants include:
- Fragrance
- Alcohol-based ingredients
- Strong soaps and cleansers
Beyond the ingredients themselves, the way you use them matters; understanding the link between overwashing and eczema is crucial, as even gentle products can trigger a flare-up if they are used too frequently or with excessively hot water. Switching to a simple, mindful cleansing routine can make a significant difference.
3. Weather Changes
Cold, dry air can strip moisture from the skin.
Hot weather and sweating can also trigger irritation.
Because of this, eczema symptoms often worsen:
- In winter due to dryness
- In summer due to heat and sweat
During warmer weather, some people may struggle to tell whether irritation is caused by eczema or heat-related skin irritation. Our guide to heat rash vs eczema rash explains the differences between the two conditions.
4. Stress
Stress does not cause eczema, but it can trigger flare-ups.
When stress levels rise:
- Inflammation in the body can increase
- Skin becomes more reactive
- Itching may worsen
Itching may worsen, particularly at night when inflammation and skin sensitivity naturally increase.
Stress-related inflammation can sometimes make flare-ups resemble hives or irritated rashes. Our guide to stress rash vs eczema rash explains how stress affects sensitive skin.
Managing stress can help reduce flare frequency. Managing stress can help reduce flare frequency and may also help shorten how long eczema flare-ups last.
Our guide to can stress trigger eczema flare-ups explains how stress affects inflammation, itching, and skin barrier function during flare-ups.
5. Allergens
Environmental allergens can trigger eczema symptoms.
These include:
- Dust mites
- Pollen
- Pet dander
Reducing exposure where possible can help improve skin comfort.
How to Identify Your Triggers
Everyone’s eczema is different.
To identify your triggers:
• Pay attention to when flare-ups happen
• Note any changes in skincare or environment
• Look for patterns over time
This helps you understand what your skin reacts to.
How to Avoid Eczema Triggers
Avoiding triggers is one of the most effective ways to manage eczema.
Transitioning to a Natural Eczema Treatment routine is often the most effective way to minimize exposure to synthetic irritants while using gentle, plant-derived ingredients to keep the skin calm.
Keep Your Routine Simple
Use fewer products and choose gentle formulations.
Stay Consistent with Moisturising
Hydrated skin is less reactive and more resilient.
Choose Fragrance-Free Products
This reduces the risk of irritation. Selecting a fragrance-free moisturiser is one of the simplest yet most effective ways to eliminate a primary source of daily irritation and support your skin barrier's natural recovery process.
Protect Your Skin from Weather
Wear protective clothing and adjust your routine with the seasons.
Supporting Your Skin Barrier
Even when avoiding triggers, your skin still needs support.
A strong skin barrier helps:
- Lock in moisture
- Protect against irritants
- Reduce sensitivity
For daily support, a gentle option like our Atopic Cream can help soothe irritation and maintain hydration.

How Triggers and Treatment Work Together
Avoiding triggers alone is not enough.
Eczema management works best when you combine:
• Trigger avoidance
• Daily hydration
• Barrier repair
Final Thoughts
Eczema triggers are a key part of managing the condition.
By understanding what affects your skin, you can:
• Reduce flare-ups
• Improve comfort
• Support long-term skin health
Small changes in your routine can make a big difference over time.
