Eczema is often described as unpredictable — but in reality, flare-ups are usually the result of multiple overlapping factors rather than a single cause. Understanding these triggers is one of the most effective ways to take back a sense of control when living with eczema.
Rather than searching for one definitive reason, it’s more helpful to view eczema as a condition influenced by genetics, environment, lifestyle and skin barrier health.
A weakened skin barrier
At the centre of eczema is a compromised skin barrier. Healthy skin acts as a protective shield, retaining moisture while keeping irritants out. In eczema-prone skin, this barrier is less effective.
When moisture escapes more easily, skin becomes dry, fragile and more reactive — increasing the likelihood of inflammation, itching and flare-ups.
This is why hydration and barrier support are so important in managing eczema-prone skin.

Genetic factors factor into eczema
Eczema often runs in families. People with a history of eczema, asthma or hay fever are more likely to develop the condition. These genetic factors can influence how the skin barrier forms and how the immune system responds to irritants.
While genetics cannot be changed, understanding this predisposition helps remove blame and frustration — eczema is not caused by poor hygiene or lifestyle choices alone.
Environmental triggers
Everyday environmental factors are among the most common eczema triggers. These may include:
- Cold or dry weather
- Heat and sweating
- Central heating or air conditioning
- Pollution and airborne irritants
Seasonal changes often bring noticeable shifts in eczema symptoms, with winter dryness and summer heat being common challenges.
Skincare and household products
Many flare-ups are linked to contact with irritating substances, such as:
- Harsh soaps or cleansers
- Fragranced skincare
- Laundry detergents or fabric softeners
- Alcohol-heavy formulations
Even products marketed as “strong” or “deep cleansing” can compromise the skin barrier over time. For eczema-prone skin, gentle and consistent care is often more supportive than intensive treatments.

Fabrics and physical irritation
Clothing can play a surprisingly large role in eczema comfort. Rough, synthetic or non-breathable fabrics may trap heat and friction against the skin, increasing irritation.
Natural, breathable materials are often better tolerated, particularly during flare-ups or warmer weather.
Stress and emotional factors
Stress does not cause eczema, but it can significantly influence flare-ups. Emotional strain can affect immune response, sleep quality and skin sensitivity — all of which may worsen symptoms.
This can create a frustrating cycle, where eczema causes stress, and stress then aggravates eczema. Acknowledging this connection allows people to approach eczema management with greater compassion for themselves.
Triggers are personal
Perhaps the most important point is this: eczema triggers are highly individual. What worsens symptoms for one person may have little effect on another.
Keeping note of patterns — such as changes in weather, products, diet or stress levels — can help identify personal triggers over time.
