Why treating the skin alone may be missing the bigger picture

When eczema is discussed, the conversation often starts in the wrong place.

The conversation usually begins with the skin barrier: It’s damaged. It’s dry. It needs more moisture. We need to seal it, protect it, and calm the inflammation.

And while the skin barrier absolutely matters, eczema is not simply a moisturizer problem, or even just a skin problem.

The skin is part of a much larger system. It communicates with the immune system, gut, nervous system, hormones, microbiome, and environment. When eczema appears, especially when it keeps coming back, it’s worth asking a much bigger question:

Why is the skin so inflamed and reactive in the first place?

Because repeatedly applying topical treatments may calm what we can see on the surface, but it doesn’t necessarily tell us what’s driving the inflammation underneath.

And this is where the conventional eczema conversation often falls short.

Eczema Is More Than a Damaged Skin Barrier

Atopic dermatitis (the most common form of eczema) is an inflammatory condition involving both skin-barrier dysfunction and immune dysregulation.

These two things are deeply interconnected.

When the skin barrier isn’t functioning optimally, allergens, irritants, and microbes can more easily interact with the immune system. At the same time, an overactive or dysregulated immune response can increase inflammation and further disrupt the skin barrier.

It can become a cycle:

Barrier disruption → exposure to irritants and allergens → immune activation → inflammation → further barrier disruption.

That’s why, from a root-cause perspective, we don’t want to stop at:

“What can we put on the eczema?”

We also want to ask:

“What is contributing to this person’s inflammatory load?”

Why Steroids Don’t Solve the Underlying Problem

Topical corticosteroids are commonly prescribed because they suppress inflammation – and they can do that effectively. But suppressing inflammation isn’t the same thing as identifying why the inflammation is occurring.

Long-term or repeated topical steroid use isn’t without risk, either. Depending on the potency, location, duration, and amount used, prolonged use can contribute to skin thinning (atrophy), easy bruising, visible blood vessels, stretch marks, changes in pigmentation, and increased susceptibility to certain skin infections. There is also growing recognition of topical steroid withdrawal (TSW), a potentially severe reaction reported after stopping prolonged or frequent topical steroid use. This doesn’t mean everyone who uses a topical steroid will experience these problems, but it is one more reason we don’t believe repeatedly suppressing eczema indefinitely should replace investigating what may be driving the inflammation in the first place.

If eczema improves while using a steroid and returns when treatment stops, the underlying factors contributing to that inflammatory response may still be present.

Symptom suppression becomes the entire strategy.

But with recurring eczema, we need to expand the conversation:

Why does the immune system keep reacting? What is repeatedly triggering the skin? What changed before the eczema began or worsened? Are internal or environmental factors continually adding fuel to the fire?

Those questions can lead us in very different – and important – directions.

1. Food Reactions + Sensitivities

Food is one area worth exploring, but it requires nuance.

Eczema and food allergy or sensitivity frequently overlap, particularly in children with moderate-to-severe atopic dermatitis. Dairy, egg, and wheat/gluten are among the common triggers among individuals. I think we can safely say that we’ve seen at least one of these three involved in every eczema patient we’ve seen.

That doesn’t mean everyone with eczema should immediately eliminate dairy, gluten, eggs, or half their diet. Instead, look for patterns. Trying an elimination diet or completing food sensitivity testing can be extremely helpful in narrowing it down.

Does eczema consistently worsen after a particular food? Are there digestive symptoms alongside it? Did symptoms begin around the introduction of certain foods? Are there other signs of allergic disease (headache, brain fog, joint pain, behavioral/mood changes, etc)?

The goal isn’t unnecessary restriction. It’s determining whether food may be contributing to inflammation in that particular person.

2. Gut + Microbiome Health

The skin and gut aren’t isolated organs. Both contain enormous microbial ecosystems, and there is an undeniable connection between the gut microbiome, immune development, allergic disease, and atopic dermatitis.

From a holistic perspective, that makes gut health difficult to ignore.

Consider digestive symptoms, constipation or diarrhea, antibiotic history, dietary diversity, fiber intake, and overall digestive function.

This doesn’t mean there’s one magical probiotic that “cures” eczema. It means that when we’re dealing with an immune-mediated inflammatory condition, gut and microbiome health deserve a seat at the table. Skin health is an outward expression of gut health.

3. Environmental Allergies

Environmental triggers play a large role, as well. Afterall, the world around us has a direct influence on how our immune system functions.

Environmental triggers may include:

• dust mites
• pollen
• pet dander
• mold (a biggie!)
• seasonal allergens

If eczema predictably worsens during certain seasons, in particular buildings, or after exposure to specific environments, pay attention. Those patterns matter.

4. Household + Personal-Care Products

This is one of the first places we’d look because our skin comes into contact with these products every single day.

Laundry detergent. Fabric softener. Dryer sheets. Hand soap. Body wash. Shampoo. Lotion. Cleaning sprays. Fragrance. All of it.

Even products marketed for “sensitive skin” can contain ingredients that don’t agree with someone’s skin. (Greenwashing is real, y’all!)

Think beyond what’s applied directly to the eczema, too. Skin spends hours touching clothing, sheets, towels, blankets, and other fabrics.

And remember: “natural” doesn’t automatically mean eczema-friendly. Essential oils and botanical ingredients can also irritate reactive skin. For eczema-prone skin, simpler is often better.

5. The Skin Microbiome

Our skin has its own microbiome.

In atopic dermatitis, that microbial ecosystem can change significantly. One well-established example involves Staphylococcus aureus, a bacterium that commonly colonizes eczema-prone skin and can become more abundant during flares.

It can create another frustrating cycle:

Inflammation alters the skin environment → microbial balance shifts → certain microbes flourish → inflammation can worsen.

It’s another reason eczema is far more complicated than simply having “dry skin.”

6. Stress + the Nervous System

Ever notice eczema flare during a stressful week? That’s not a coincidence.

The skin and nervous system communicate constantly, and stress can influence immune activity, inflammation, itching, and skin-barrier function.

Then another cycle can begin:

Stress → itching/inflammation → poor sleep → more stress → more itching.

For children, stress can look like changes at school, disrupted routines, poor sleep, illness, travel, or overstimulation.

This doesn’t mean eczema is “caused by stress.” It means stress physiology can influence inflammatory conditions and shouldn’t be ignored.

7. Hormonal Changes

If eczema suddenly changes during puberty, pregnancy, postpartum, perimenopause, or different phases of the menstrual cycle, pay attention to the timing.

Hormones influence immune function, skin hydration, barrier integrity, and inflammatory signaling.

Some women notice eczema improves during certain hormonal stages while others experience worsening.

Again, we’re looking for patterns – not assuming every case has the same cause.

8. Nutrient Status

Healthy skin requires nutrients. So does the immune system.

Nutrients involved in skin and immune health include vitamin D, zinc, essential fatty acids, vitamins A and E, iron, selenium, B vitamins, and adequate protein.

This doesn’t mean everyone with eczema needs a supplement protocol.

But in chronic or difficult-to-manage cases – particularly with restrictive diets, digestive problems, poor appetite, or other signs of deficiency – nutrient status is worth evaluating.

9. Heat, Sweat + the Physical Environment

Sometimes triggers are surprisingly simple. Heat and sweating are common eczema aggravators. So are very dry environments, sudden temperature changes, scratchy fabrics, chlorine, prolonged hot showers, and friction against the skin.

Did the weather change? Was there a sweaty sports practice? Did you switch pajamas? Start swimming? Travel somewhere humid?

Small details can reveal surprisingly consistent patterns. But these triggers still tell us there’s dysfunction within the system that needs to be addressed. These are just more clues.

Become an Eczema Detective

When eczema is chronic, recurring, or suddenly worsening, stop looking at each flare in isolation.

Keep a simple eczema journal and track:

• foods and possible reactions (keep in mind that food proteins can stay in the body for days, and even weeks – it’s not always what you just ate)
• digestion (bloating, gas, constipation, diarrhea, nausea…take note of patterns)
• new household or personal-care products
• environmental exposures and seasonal changes
• stress and sleep
• hormonal changes
• heat, sweat, swimming, and activity

You may not see anything immediately. But over several weeks, patterns can emerge – and those patterns may provide far more useful information than simply asking which cream to try next.

When You Need Help Looking Deeper

Trying to identify eczema triggers can feel a little like putting together a puzzle – and you don’t have to sort through it alone. Working with a knowledgeable integrative or functional medicine provider can help you look for patterns and investigate potential underlying contributors such as food reactions, gut and microbiome health, nutrient status, environmental exposures, allergies, hormones, and other sources of inflammation. The goal isn’t to chase every possible “root cause” or order every test available. It’s to look at the whole person, their history, and their individual symptoms to determine which areas actually make sense to investigate.

Support the Skin – But Don’t Stop at the Skin

None of this means we ignore uncomfortable, itchy, inflamed skin while we’re looking for underlying contributors. Supporting the skin during the healing process matters, too.

Gentle bathing, avoiding known irritants, protecting damaged skin, and using simple topical products can help provide much-needed support while you’re working on the bigger picture.

For those looking for topical options with simpler ingredients, two that we like are:

SilverCeuticals Eczema Relief & Skin Therapy Cream – designed specifically for irritated, eczema-prone skin and a nice option when the skin needs extra soothing support.

Root Avenue Bare Body Butter or Tallow Whip – a simple, rich tallow-based moisturizer that can help support very dry skin and the skin barrier without a long list of conventional skincare ingredients.

The important distinction is this: topical products are supportive – not the entire solution. You can soothe and protect the skin while simultaneously asking why it became so reactive in the first place. It’s necessary to do both.

Eczema Is a Signal Worth Listening To

Eczema is complex. Genetics, skin-barrier function, immune activity, microbes, allergens, environmental exposures, nutrition, stress, and hormones can all overlap. But finding the root cause(s) is very DOABLE!

Instead of only asking:

“How do we make this rash disappear?”

We can also ask:

“Why is this person’s skin struggling so much in the first place?”

Maybe there’s a food trigger. Maybe there’s an environmental allergy. Maybe a fragranced laundry product is continually irritating sensitive skin. Maybe the microbiome has changed. Maybe stress, hormones, or poor sleep are amplifying the inflammatory response.

Or maybe several things are happening at once.

Eczema is not simply a defective skin barrier that needs to be covered with increasingly stronger products. The skin barrier matters enormously. It’s just not the whole story.

For chronic or recurring eczema, people deserve a conversation that looks beyond the surface – at the immune system, gut, environment, lifestyle, exposures, nutrition, hormones, and the individual patterns that make each person’s eczema different.

Because the goal shouldn’t only be to quiet the skin.

The goal should also be to understand why it’s asking for our attention in the first place.
