If you have lived with eczema for any length of time, you have probably become an involuntary expert in your own skin. You know the feeling that comes just before a flare - the tightening, the first hint of itch, the way certain things reliably set it off and others do not. You have likely made adjustments to your life that most people around you would not even think to make. Different washing powder. Gloves for washing up. Checking the weather before deciding what to wear.
And still, sometimes, a flare arrives anyway. With no obvious cause. No new product, no change in routine, nothing you can point to. Just your skin doing what it does - and all the frustration that comes with it.
This article will not tell you anything you have already heard if you have been managing eczema for years. What it will do is pull the triggers together in one honest place, including the less-talked-about ones, explain what is actually happening in the skin when a flare begins, and look at what can genuinely help calm things down and reduce how often flares happen. Not cure. Not eliminate. Calm and reduce.
What is actually happening during an eczema flare
Understanding the mechanism helps because it changes what you reach for when things escalate.
Eczema is a chronic inflammatory condition associated with impaired skin barrier function and an overactive immune response. The skin barrier in eczema does not function the way it does in unaffected skin. It loses moisture more rapidly, allows irritants and allergens to penetrate more easily, and responds to those irritants with disproportionate inflammation.
This is why eczema flares can be set off by things that most people's skin handles without any response at all. A soap that contains fragrance. A temperature change. A stressful week. For most people, these are non-events for the skin. For eczema-prone skin, they are enough to start a cascade.
The itch-scratch cycle is central to how flares escalate. Inflammation causes itch. Scratching damages the barrier further, which allows more irritants in, which triggers more inflammation, which causes more itch. Breaking this cycle - reducing the inflammation and supporting the barrier before the scratching does further damage - is the practical goal of flare management.
The most common eczema triggers - and the ones people miss
Skincare and household products
This is the trigger category that is most directly within your control, and also the one where the most damage is quietly done.
Synthetic fragrance is the single most common contact irritant in skincare and household products. It is listed as "parfum" on ingredient labels and can represent a blend of dozens of compounds, none of which are individually disclosed. For eczema-prone skin, fragrance is one of the most consistent and avoidable triggers in daily life - not just in skincare, but in washing powder, fabric softener, cleaning products, candles, and air fresheners.
Sodium lauryl sulphate and related surfactants, found in most conventional cleansers, shower gels, and shampoos, are known to strip the skin barrier and worsen eczema symptoms. Even products labelled as gentle or moisturising can contain enough SLS to cause problems for sensitive skin.
Preservatives - particularly methylisothiazolinone and formaldehyde-releasing preservatives - are common allergens that appear in many skincare, haircare, and household products. They can be difficult to identify on labels without familiarity with their names.
Wet work - prolonged contact with water, particularly hot water - removes the skin's natural oils and disrupts the barrier. Repeated hand washing, dishwashing without gloves, and long hot showers or baths all fall into this category. The damage is cumulative and often underestimated.
If you are not sure whether a product is safe for your skin, Yuka is worth downloading. It lets you scan the barcode of anything, from washing powder to shampoo, and gives you an honest breakdown of what is actually in it. It is free, simple to use, and one of the most practical tools I have come across for taking the guesswork out of ingredient checking.
Fabrics and clothing
Wool and synthetic fabrics are among the most consistent clothing triggers for eczema, causing physical irritation to an already sensitised barrier. Cotton and bamboo, worn loosely, are generally much better tolerated.
Labels and seams can cause localised irritation at specific sites. Removing labels and choosing seamless clothing where possible is a small change that makes a real difference for many eczema sufferers.
Washing powder and fabric softener residue left in clothing after washing is a less visible but very consistent trigger. Fragrance-free, non-biological washing powders, rinsed thoroughly, are the standard recommendation - and fabric softener, which coats fibres with fragrance and chemical compounds, is worth removing entirely.
Environmental and seasonal triggers
Temperature extremes are a reliable eczema trigger in both directions. Heat causes sweating, which irritates the skin. Cold and dry air strips moisture from the barrier and leaves it more vulnerable. Central heating reduces indoor humidity significantly during the winter months, which dries the skin from the environment as well as through the barrier. A humidifier in the bedroom during winter is a practical intervention that many eczema sufferers find genuinely helpful.
Pollen and other airborne allergens can trigger eczema flares, particularly during spring and summer. This is more common in people who have other atopic conditions - hay fever or asthma - alongside their eczema, because the immune system is already primed for overresponse. Showering after being outdoors during high pollen periods and keeping windows closed on high-count days can reduce exposure.
Dust mites are one of the most common environmental triggers for eczema, particularly in children. Washing bedding at 60 degrees, using dust mite-proof covers on mattresses and pillows, and vacuuming regularly with a HEPA-filter vacuum can reduce dust mite load significantly.
Food
Food triggers for eczema are real but individual. There is no single food that triggers eczema universally, and the relationship between diet and eczema is more complex than it is sometimes presented.
The foods most commonly associated with eczema in children - dairy, eggs, wheat, soy, nuts - are less consistently linked in adult eczema. For some adults, however, food does play a role, and identifying personal triggers through a careful elimination approach - removing a suspected food for four to six weeks and observing the skin - is a reasonable way to investigate.
Alcohol is worth mentioning separately. It dehydrates, disrupts sleep, and has vasodilatory effects that can increase skin flushing and inflammation. For eczema-prone skin, alcohol is one of the more consistently reported dietary triggers.
Stress
Stress deserves its own section because it is both one of the most consistent eczema triggers and one of the least directly addressed.
The relationship between stress and eczema is bidirectional. Stress triggers flares - cortisol and other stress hormones affect the immune system and increase inflammatory responses in the skin. And flares cause stress - the discomfort, the visibility, the exhaustion of managing a chronic condition. This cycle can feel inescapable, particularly during periods of sustained pressure.
The practical implication is that stress management is not a nice addition to eczema care - it is a genuine part of it. Exercise, adequate sleep, and whatever specific practices bring your nervous system down are as relevant to your skin as what you put on it. The connection between stress and skin inflammation is worth understanding, because it reframes stress management as a skin intervention rather than a general wellness aspiration.
Illness and infection
Skin infections - particularly Staphylococcus aureus, a bacterium that colonises the skin of the vast majority of people with eczema - are both a trigger and a consequence of flares. The bacteria thrive in eczema-affected skin and contribute to the inflammatory cycle. If your flares are accompanied by weeping, crusting, or signs of infection, it is worth discussing with your GP, as a bacterial infection may need treatment before the skin can begin to settle.
Viral illness more broadly can trigger eczema flares, as the immune system's response to infection spills over into skin inflammation. This is often why eczema worsens when children - or adults - are unwell with colds or other infections.
Gut Health
Gut health is another piece of the puzzle that is genuinely worth paying attention to. The connection between the gut microbiome and skin inflammation is increasingly well-supported by research, and many people with eczema find that what is happening internally shows up on their skin. Prioritising fermented foods like kefir, sauerkraut, and live yoghurt, reducing processed sugar, and considering a good quality probiotic are low-risk steps that can make a real difference over time. It is not a quick fix, and it will not work the same way for everyone, but if you have been focusing entirely on what goes on your skin and ignoring what goes into your oi9 v0, it is worth broadening that view.
What actually helps during a flare
Managing a flare is different to managing eczema day to day. During a flare, the goal is to calm the skin, protect the barrier, and break the itch-scratch cycle as quickly as possible.
Keep the skin moisturised and protected. During a flare, the barrier is at its most compromised, and moisture loss is at its highest. Applying something protective and barrier-supporting frequently - even hourly on particularly affected areas - helps to reduce the moisture loss that drives the inflammation cycle. The most important quality of whatever you apply is that it is tolerated. Something with minimal ingredients and no fragrance is a safer ground for reactive, flaring skin than a product with a complex formulation, however well-intentioned.
For areas of intense dryness and irritation, Calm Butter is what we made for exactly this kind of moment. It is a rich, balm-like butter containing shea butter, mango butter, jojoba oil, vegetable glycerin, and tapioca starch - no water, no synthetic fragrance, no unnecessary ingredients. It scores 100/100 on Yuka. Shea butter in particular has well-established anti-inflammatory properties and is one of the most consistently tolerated natural emollients available. For skin in the middle of a flare that needs protection and nourishment without the risk of additional irritants, five clearly listed ingredients are a very different proposition to most mainstream emollients.
Cool the skin. Heat drives itch. Cool water compresses, cool showers rather than hot baths, loose breathable clothing, and keeping the environment at a moderate temperature all help reduce the intensity of itch during a flare.
Keep the bedroom cool at night. Body temperature naturally rises during sleep, and a warm room can intensify the itch cycle at exactly the moment your skin should be resting and recovering. A cool, well-ventilated bedroom, light cotton bedding, and avoiding electric blankets or thick duvets during a flare can make a genuine difference to how settled the skin is overnight.
Keep nails short and use cotton gloves at night. Scratching during sleep is often more damaging than any conscious scratching during the day, because there is no awareness of how long or hard the scratching is happening. Cotton gloves overnight reduce the barrier damage from night scratching significantly.
Avoid everything new. A flare is not the time to introduce anything untested. The barrier is already compromised, and the skin is in a heightened reactive state. Stick to what you know is tolerated.
See your GP if the flare is severe or prolonged. If a flare is not calming within a week of consistent management, if there are signs of infection, or if the skin is significantly affecting daily life or sleep, a GP appointment is the right call. Topical steroids, used short-term and as directed for flares, can be appropriate and effective. The key is short-term use, not the long-term continuous application that can lead to its own complications.
What helps between flares - reducing how often they happen
Managing eczema well is less about dramatic interventions and more about consistent, quiet maintenance between flares. The goal is to keep the barrier as strong and stable as possible so that triggers have less to work with.
A minimal, fragrance-free daily routine. The fewer ingredients touching the skin each day, the fewer opportunities for a trigger. A simple cleanser, a barrier-supporting product, and sun protection is the foundation. Everything else is worth questioning.
Illuminate Face Oil is where most of our eczema customers start. Three ingredients - jojoba oil, argan oil, and vitamin E - each chosen for a specific reason and none of them unnecessary. Jojoba, as a liquid wax that closely mimics the skin's own sebum, supports the barrier in a way that is exceptionally well-tolerated by eczema-prone skin. Argan brings essential fatty acids and a natural softness. Vitamin E is an antioxidant that supports the skin's own healing processes and protects against environmental damage. No water, no fragrance, 100/100 on Yuka.
We would never claim Illuminate will stop eczema flares. What we can say is that for skin that needs daily, consistent barrier support with the fewest possible ingredients, it is an honest and transparent starting point. Why natural face oils suit eczema-prone skin is covered in detail elsewhere if you want to understand the reasoning before deciding.
Consistent emollient use. Applying a barrier-supporting product at least twice a day - morning and night - even when the skin is calm, is one of the most consistently evidenced approaches to reducing eczema flare frequency. The barrier needs regular maintenance, not just attention when things go wrong.
Identifying and reducing your personal triggers. The triggers listed in this post are the most common ones. Your triggers will be a subset of these, and possibly some that are specific to you. Keeping a simple diary - products used, environment, diet, stress levels, sleep, and skin state each day - over a few weeks can help identify patterns that are not always obvious in the moment.
Protecting sleep. Sleep deprivation worsens inflammation, increases cortisol, and reduces the skin's ability to repair itself overnight. For eczema, consistently poor sleep does not just make the days harder - it makes the skin more reactive. Treating sleep as a genuine part of eczema management, rather than something that suffers when the skin makes nights difficult, is worth prioritising.
The bigger picture
Eczema is a condition that many people manage for years or decades. It changes with age, with seasons, with life circumstances. What triggers a flare at thirty may not be what triggers one at forty. What worked last winter may not work this one.
The most honest thing we can say is that there is no single answer that works for everyone, and anyone who tells you otherwise has not spent enough time with the real experience of chronic eczema. What it actually looks like to navigate eczema and find an approach that works is covered in more depth elsewhere, and it is worth reading if you want the fuller picture rather than just the triggers.
What we do know is that eczema-prone skin does better with simplicity, consistency, and gentleness than with anything dramatic. It does better with fewer ingredients than more. It does better when stress is taken seriously as a trigger and not just a background condition. And it does better when the people caring for it - including you - stop expecting overnight results and start thinking in terms of gradual, careful improvement over weeks and months.
You have been managing this for a long time. You deserve support that is honest about what it can and cannot do - and that actually works with your skin, not against it.
