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
• Dyshidrotic eczema
Why We Became Interested In Eczema Triggers
Over the years, one of the most common conversations we have had with people living with eczema is about flare-ups that seem to appear without warning.
As we listened to hundreds of customers and families dealing with eczema-prone skin, a pattern began to emerge. Many people were unknowingly exposing their skin to triggers that were weakening the skin barrier and making symptoms worse.
This helped shape our understanding of eczema management. While every person's triggers are different, we have repeatedly seen how identifying irritants, simplifying skincare routines and supporting the skin barrier can help many people reduce flare-ups and improve comfort over time.
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.
The Emotional Side Of Eczema Flare-Ups
One of the things we have learned over the years is that eczema flare-ups often affect much more than just the skin itself. Many people become extremely self-conscious during flare-ups, especially when the irritation appears on visible areas like the arms, hands, face, or neck.
One of the early people we worked with was a young local footballer named Joseph, who struggled badly with eczema. During flare-ups, he often felt uncomfortable showing his skin and would regularly try to keep his arms and legs covered, even while playing sport in warm weather.
As we worked closely with him and his family over time, we began noticing something important that we still hear from many customers today flare-ups were often made worse by irritation, overwashing, harsh products, stress, and constantly aggravating already-sensitive skin.
Over several weeks of carefully introducing gentle skincare and reducing unnecessary irritation, Joseph’s skin gradually became calmer and more comfortable. But perhaps more importantly, his confidence improved too, and eventually he felt comfortable enough to stop trying to hide his skin while playing football.
Experiences like these have shaped Bragan Skincare’s understanding of eczema triggers and flare-ups. We know that everybody’s skin behaves differently, and triggers can vary from person to person. However, after years of working with people dealing with eczema-prone skin, we strongly believe that gentle skincare routines, consistency, and avoiding unnecessary irritation can make a meaningful difference for many people over time.
Mags' Story: The Power of Consistency
We recently met Mags at a show where she stopped by our stand to tell us about her experience with Bragan Skincare's Atopic Cream. Like many people living with eczema, Mags had spent years trying different creams and treatments in search of relief. Despite trying what felt like everything available, she still struggled to find a skincare routine that worked for her skin over the long term.
Mags met us at a recent show to share her story.
What stood out most during our conversation was her advice to others. Mags believes that consistency was the key. Rather than expecting overnight results, she committed to using the cream regularly as part of her daily skincare routine and gradually began to see improvements in her skin.
Her story reflects something we often hear from customers: managing eczema is rarely about finding a quick fix. Instead, it's about supporting the skin barrier consistently over time with gentle skincare.
While every person's skin is different and no product works for everyone, Mags' experience highlights the importance of patience, consistency and finding a routine that works for your skin. If you'd like to hear Mags share her story in her own words, you can watch her video testimonial here.
