Eczema (Atopic Dermatitis): Types, Triggers, Treatments, and the Functional Medicine Approach

Eczema is a group of chronic, relapsing inflammatory skin conditions, and its most common form, atopic dermatitis (AD), comes from a leaky skin barrier combined with an overactive type 2 (Th2) immune response that together cause dry, itchy, inflamed skin. Atopic dermatitis affects up to 25% of children and 7.3% of US adults, according to the Atopic Dermatitis in America Study (Chiesa Fuxench et al., 2019), and it is managed with daily moisturizers, anti-inflammatory medicines from topical steroids to biologics, and trigger control.

If you or your child has eczema, you already know the drill. The itching that wakes you at 2 a.m. The cracked, bleeding skin that stings in the shower. The frustration of trying cream after cream, diet after diet, wondering if anything will actually work.

You are not alone. Eczema is one of the most common skin conditions on the planet. And while no single treatment works for everyone, there is a lot more you can do about it than you might think.

The sections below walk through the different types of eczema, what causes flares, how dermatologists diagnose and treat it, and which regenerative and functional medicine approaches have early support. Whether you are newly diagnosed or have managed eczema for decades, the goal is the same: fewer flares, calmer skin and better sleep. For a condition overview you can share with family, see the eczema condition page.

What Is Eczema, Exactly?

Eczema is an umbrella term for a group of conditions that make the skin inflamed, itchy, and often cracked or blistered. The most common form is atopic dermatitis, which accounts for the majority of eczema cases and is closely linked to the “atopic triad” of eczema, asthma, and allergic rhinitis (hay fever).

At its core, eczema is a problem with the skin barrier. Think of healthy skin like a brick wall: skin cells are the bricks, and lipids (fats) are the mortar holding everything together. In eczema, that mortar is defective. The wall has gaps. Moisture escapes, and irritants, allergens, and bacteria get in.

This triggers an immune overreaction, primarily driven by T-helper 2 (Th2) cells. The immune system sounds the alarm even when the threat is minor, creating a cycle of inflammation, itching, scratching, and more inflammation. Researchers call this the “itch-scratch cycle,” and breaking it is one of the central goals of treatment.

Is eczema the same as atopic dermatitis?

Atopic dermatitis is one type of eczema, not a separate disease. Clinicians use the terms eczema, atopic eczema, atopic dermatitis and AD almost interchangeably for the common chronic, itchy form, while "dermatitis" on its own simply means skin inflammation. Contact dermatitis, seborrheic dermatitis and stasis dermatitis are eczema types with different causes, so the label on your chart shapes which treatment makes sense.

Atopic dermatitis also travels with other allergic conditions. Many children with early eczema later develop food allergy, asthma or hay fever, a sequence called the atopic march. Its look-alike, psoriasis, is a different immune disease with thicker, sharply edged, silvery plaques; the psoriasis vs eczema comparison covers how to tell them apart.

The Six Main Types of Eczema

Not all eczema looks or behaves the same. Here are the six primary types, each with distinct features and triggers.

1. Atopic Dermatitis

This is the big one. Atopic dermatitis (AD) usually starts in infancy or early childhood and often runs in families with a history of allergies, asthma, or hay fever. It tends to appear on the cheeks and scalp in babies, the creases of elbows and knees in older children, and the hands, neck, and eyelids in adults.

AD is a chronic condition. Some children outgrow it by adolescence, but many carry it into adulthood. Severity ranges from mild dry patches to widespread, weeping, crusted plaques that seriously impact quality of life.

2. Contact Dermatitis

This type flares when your skin touches something it does not like. There are two subtypes:

• Irritant contact dermatitis: Caused by direct chemical damage from substances like detergents, solvents, or frequent hand washing. No allergy involved.
• Allergic contact dermatitis: A true immune-mediated reaction to a specific substance, such as nickel, fragrance, latex, or poison ivy. It takes prior sensitization, meaning you will not react the first time, but once your immune system is primed, even tiny exposures can trigger a rash.

3. Dyshidrotic Eczema (Pompholyx)

Small, intensely itchy blisters appear on the palms, sides of fingers, and soles of the feet. It can be triggered by stress, sweating, contact with metals like nickel or cobalt, or seasonal allergies. The blisters may take weeks to resolve, and the skin often peels and cracks as they dry out. The dyshidrotic eczema guide goes deeper on blister flares and their triggers.

4. Nummular Eczema (Discoid Eczema)

Coin-shaped (nummular) patches of irritated skin, usually on the legs, arms, or torso. These round lesions can be quite stubborn and are sometimes mistaken for ringworm. Nummular eczema is more common in men and tends to show up after skin injuries like insect bites or burns. Dry skin in winter is a frequent trigger. Because round patches can also be fungal, a dermatologist may scrape a patch for a KOH test before treating it. The nummular eczema overview goes deeper on this type.

5. Seborrheic Dermatitis

This affects areas rich in oil glands: the scalp, face (especially around the nose, eyebrows, and ears), and upper chest. In infants, it is called “cradle cap.” The yeast Malassezia, which naturally lives on the skin, plays a role in driving the inflammation. Flares are common during cold weather, stress, or illness.

6. Stasis Dermatitis (Venous Eczema)

This type develops on the lower legs due to poor blood circulation, specifically chronic venous insufficiency. Blood pools in the leg veins, pressure builds, and fluid leaks into the surrounding tissue, causing swelling, discoloration, itching, and eventually eczema. If untreated, it can lead to skin ulcers. It is most common in older adults and people with a history of blood clots or varicose veins.

Causes and Triggers: Why Does Eczema Happen?

Eczema is not caused by one single thing. It results from a collision of genetics, immune dysfunction, environmental exposures, and lifestyle factors. Here is how they interact.

Genetics and the Skin Barrier

Up to 50% of people with moderate-to-severe atopic dermatitis carry mutations in the filaggrin gene (FLG). Filaggrin is a protein that helps build and maintain the outermost layer of skin. Without enough of it, the skin barrier is compromised from the start. The link was established by Palmer et al. in Nature Genetics (2006), who found that two common FLG loss-of-function variants, carried by about 9% of people of European origin, are very strong predisposing factors for atopic dermatitis and for asthma that occurs alongside it.

But genetics are not destiny. Plenty of people with filaggrin mutations never develop eczema, and many eczema patients have normal filaggrin genes. That is where environment and lifestyle come in.

Immune System Imbalance

In atopic dermatitis, the immune system is skewed toward a Th2 response. This means it produces too much of certain inflammatory molecules (like interleukin-4, interleukin-13, and interleukin-31) and not enough of the antimicrobial peptides that protect against infection. The result: inflamed skin that is also prone to bacterial and viral infections.

Common Triggers

• Dry air and low humidity (winter months are notorious)
• Harsh soaps, detergents, and fragrances
• Allergens: dust mites, pet dander, pollen, mold
• Food sensitivities (especially dairy, eggs, wheat, soy, and nuts in children)
• Stress (raises cortisol, which can worsen skin barrier function)
• Heat and sweating
• Certain fabrics (wool, synthetic materials)
• Infections: Staphylococcus aureus colonizes the skin of most people with AD, with older studies reporting rates as high as 90%
• Hormonal shifts (many women notice flares around their menstrual cycle or during pregnancy)

A simple trigger diary is the most practical tool here. Note new products, foods, weather, sweat, sleep and stress on the days before each flare, and patterns usually appear within a few weeks. The eczema triggers breakdown lists the common culprits by category.

Recognizing the Symptoms

The hallmark symptom across all types of eczema is itch. In atopic dermatitis, the itch often precedes the rash. Patients describe it as relentless, deep, and maddening. Scratching provides momentary relief but worsens the inflammation.

Beyond itching, here is what to look for:

• Dryness: The skin feels rough, tight, and flaky, even between flares
• Redness and inflammation: Active patches are pink to dark red (or may appear brown, purple, or ashen gray on darker skin tones)
• Oozing and crusting: In acute flares, the skin may weep clear fluid and form yellowish crusts
• Thickened skin (lichenification): Chronic scratching causes the skin to become thick, leathery, and deeply lined
• Cracking and fissures: Deep cracks that can bleed and sting, especially on hands and feet
• Sleep disruption: The itch is often worst at night, leading to chronic sleep deprivation

Where eczema shows up also changes how it behaves. Hand eczema is often driven by wet work and irritants, while facial and eyelid eczema calls for gentler medicines on thin skin; the guides to eczema on the hands and eczema on the face cover each area.

How Is Eczema Diagnosed?

Eczema is diagnosed clinically: a dermatologist, pediatrician or primary care clinician looks at the rash, where it sits and how it has behaved over time. No single blood test confirms atopic dermatitis. Most clinicians lean on criteria first described by Hanifin and Rajka in 1980, or the simpler UK Working Party criteria, which center on itchy skin plus a typical pattern, an early start and a personal or family history of atopy.

Which tests are used for eczema?

Tests are used to find triggers or rule out look-alikes, not to prove eczema exists. The table below shows which test answers which question.

How is eczema severity measured?

Severity is scored with validated tools so treatment decisions and progress are tracked consistently. The Eczema Area and Severity Index (EASI) and SCORAD (SCORing Atopic Dermatitis) grade redness, swelling, scratch marks and thickening across the body, and the Investigator's Global Assessment (IGA) rates skin from clear to severe. The Patient-Oriented Eczema Measure (POEM) records itch, sleep loss and weeping in your own words. Insurers often ask for these scores before approving a biologic or JAK inhibitor.

Conventional Treatments: What Mainstream Medicine Offers

Let’s walk through the treatment ladder, from first-line options to the newest advanced therapies.

Step 1: Moisturizers (Emollients)

This is the foundation of all eczema care. A good emollient repairs the skin barrier, locks in moisture, and reduces the need for medicated treatments. Apply generously at least twice daily, and always within a few minutes after bathing.

Look for fragrance-free, dye-free options. Ointments (like petroleum jelly) are more effective than creams, and creams are more effective than lotions. Some newer “prescription emollients” contain skin barrier repair ingredients like ceramides and palmitoylethanolamide (PEA). For a side-by-side look at ointments, ceramide creams and medicated options, see the eczema cream comparison.

Step 2: Topical Corticosteroids

These remain the go-to treatment for eczema flares. They work by suppressing the local immune response and reducing inflammation quickly.

Steroids come in seven potency classes, from mild (hydrocortisone 1%) to super-potent (clobetasol propionate 0.05%). The general rule: use the lowest potency that controls the flare, for the shortest time needed. Thicker skin areas like palms and soles can handle stronger steroids; thinner skin like the face and eyelids requires milder formulations.

Common concerns: Skin thinning, stretch marks, and rebound flares with long-term use. These risks are real but often overstated for short-term, appropriate use. The bigger problem in practice is steroid phobia, where patients under-treat flares out of fear and end up worse off.

Topical steroid withdrawal (TSW), sometimes called red skin syndrome, is a separate concern patients raise often. It has been described after months or years of frequent, potent steroid use, most often on the face and genitals, and causes burning, spreading redness when the steroid is stopped. It is uncommon and still poorly defined, which is one more reason to follow a step-down plan with your prescriber.

Step 3: Topical Calcineurin Inhibitors (TCIs)

Tacrolimus (Protopic) and pimecrolimus (Elidel) are non-steroidal anti-inflammatory creams that work by blocking calcineurin, an enzyme involved in T-cell activation. They are especially useful for sensitive areas like the face, eyelids, and groin where long-term steroid use is not ideal.

They can cause a temporary burning or stinging sensation when first applied. This usually fades after a few days. The FDA placed a black box warning about a theoretical lymphoma risk in 2006, but large-scale studies since then have not confirmed an increased risk with normal use.

Step 4: PDE4 Inhibitors

Crisaborole (Eucrisa) is a topical phosphodiesterase-4 (PDE4) inhibitor approved for mild-to-moderate atopic dermatitis. It is another steroid-free option, though some patients find it stings on application and its efficacy is modest compared to mid-potency steroids.

The topical options widened in 2024. The FDA approved roflumilast 0.15% cream (Zoryve), a once-daily PDE4 inhibitor, for mild to moderate atopic dermatitis in people 6 and older, and tapinarof cream (Vtama), an aryl hydrocarbon receptor agonist, for atopic dermatitis in adults and children 2 and older. Both are steroid-free and can be used on large areas, though insurance coverage varies.

Step 5: Phototherapy

Narrowband UVB phototherapy (delivered in a dermatologist’s office two to three times per week) can be very effective for widespread eczema that is not adequately controlled with topical treatments alone. It works by suppressing the overactive immune cells in the skin and has a long safety and efficacy track record. Narrowband UVB uses a tight band of light around 311 to 313 nm, and a course usually runs for several weeks before the full effect shows.

Step 6: Systemic Therapies

For moderate-to-severe eczema that does not respond to topical treatments and phototherapy, systemic (whole-body) medications enter the picture.

The Regenerative and Functional Medicine Approach

Conventional treatments focus on controlling symptoms from the outside in. Regenerative and functional medicine asks a different question: what is driving the inflammation from the inside out?

This is not about rejecting conventional treatments. It is about layering in strategies that address root causes, support the body’s own healing systems, and potentially reduce the need for long-term medications. Many patients do well combining both approaches.

Be clear-eyed about the evidence. Most functional medicine work for eczema, such as stool testing, nutrient panels and supplement protocols, is cash pay, and the research behind it is smaller and less consistent than the trials behind biologics. The approach is usually led by functional or integrative medicine physicians (MDs and DOs), naturopathic doctors and registered dietitians, ideally in contact with your dermatologist. The eczema treatment guide sets out which options have the strongest support, and the functional medicine explainer covers how these visits usually work.

The Gut-Skin Axis: Your Microbiome Matters

One of the most exciting areas of eczema research involves the gut. The connection is straightforward: an often-cited estimate holds that roughly 70% of your immune system lives in and around your gut. When the gut microbiome is disrupted (a state called dysbiosis), it can shift the immune system toward the Th2 dominance that drives eczema.

Multiple studies have found that infants who develop eczema tend to have less diverse gut bacteria, with lower levels of beneficial species like Bifidobacterium and Lactobacillus, and higher levels of potentially harmful bacteria like Clostridium difficile and Staphylococcus.

The concept of “leaky gut” (increased intestinal permeability) also applies here. When the gut lining becomes too permeable, food proteins and bacterial toxins enter the bloodstream and trigger systemic immune activation, which can worsen skin inflammation. Most of this evidence is observational, and intestinal permeability tests are not standardized, so treat it as a working theory. The leaky gut overview explains what is and is not established.

Probiotics

The evidence for probiotics in eczema is most convincing for prevention. A landmark meta-analysis published in the Journal of Allergy and Clinical Immunology found that giving probiotics to pregnant women and their infants reduced the risk of eczema by about 20-25%.

For treating existing eczema, results are more mixed. A 2018 Cochrane review by Makrgeorgou and colleagues concluded that probiotics probably make little or no difference to eczema symptoms in people who already have the condition, although individual strains have shown benefit in smaller trials. The strains with the most supportive evidence include:

• Lactobacillus rhamnosus GG
• Lactobacillus reuteri
• Bifidobacterium lactis
• Multi-strain combinations

Not all probiotics are created equal. Strain, dose, and timing all matter. The research suggests that multi-strain formulas given at adequate doses (at least 1 billion CFU daily) for a minimum of 8-12 weeks are most likely to show benefit.

Evidence: Moderate

Elimination Diets and Food Sensitivities

Food does not cause eczema. But in a subset of patients, especially children under five, food sensitivities can trigger or worsen flares. The most common culprits are:

• Cow’s milk
• Eggs
• Wheat
• Soy
• Peanuts and tree nuts
• Fish and shellfish

The gold standard for identifying food triggers is a supervised elimination diet followed by controlled reintroduction. Remove the suspected food completely for 4-6 weeks, then reintroduce it and monitor for flares.

A word of caution: do not eliminate multiple food groups long-term without guidance from a qualified practitioner. Overly restrictive diets, especially in growing children, can lead to nutritional deficiencies. IgG food sensitivity panels are widely marketed but have not been validated as reliable tools for guiding eczema treatment. The eczema diet guide covers how to run an elimination and reintroduction safely.

Evidence: Moderate (for targeted elimination in children with confirmed food allergy)

Vitamin D

Vitamin D plays a direct role in skin barrier function and immune regulation. It stimulates the production of antimicrobial peptides (like cathelicidin) that help fight off the Staphylococcus aureus colonization so common in eczema.

Multiple studies have found that eczema patients tend to have lower vitamin D levels, and that supplementation can improve symptom severity, particularly during winter months when levels naturally drop. A randomized controlled trial in the Journal of Allergy and Clinical Immunology found that 1,000 IU of vitamin D daily significantly reduced winter eczema severity in children. That trial, led by Camargo et al. (2014), enrolled 107 children in Mongolia, a population likely to run low on vitamin D in winter, and lasted one month, so the result may not carry over to people with normal levels.

Practical recommendation: Get your blood levels tested. The sweet spot for most people is a serum 25(OH)D level of 40-60 ng/mL. Most adults will need 2,000-5,000 IU of vitamin D3 daily to reach that range, though individual needs vary.

That 40 to 60 ng/mL range is a target many functional medicine clinicians use; standard US labs and the National Academies treat 20 ng/mL as adequate for bone health. The NIH Office of Dietary Supplements lists 4,000 IU daily as the upper limit for adults, so doses above it belong under a clinician with follow-up blood tests. The vitamin D optimization guide covers testing and dosing.

Evidence: Moderate (strongest in children with low winter vitamin D)

Omega-3 Fatty Acids (Fish Oil)

Omega-3 fatty acids (EPA and DHA) from fish oil have well-established anti-inflammatory properties. They compete with pro-inflammatory omega-6 fatty acids for incorporation into cell membranes, and they give rise to specialized pro-resolving mediators (SPMs) that actively turn off inflammation.

The clinical evidence for fish oil in eczema is encouraging but not overwhelming. Some studies show meaningful improvements in itch and severity scores, while others show modest or no benefit. The dose likely matters. Most positive studies used at least 1-3 grams of combined EPA and DHA daily. The omega-3 dosing guide explains how to read EPA and DHA on a label.

Even if the direct skin benefits are modest, omega-3 supplementation supports overall immune balance, cardiovascular health, and mental health, all of which are relevant for people living with a chronic inflammatory condition.

Evidence: Moderate

Red Light Therapy (Photobiomodulation)

Red light therapy uses low-level wavelengths of red and near-infrared light (typically 630-850 nm) to stimulate cellular repair and reduce inflammation. Unlike UV phototherapy, it does not carry a risk of skin cancer or accelerated aging.

The proposed mechanism is well described at the cellular level: red and near-infrared light is absorbed by cytochrome c oxidase in the mitochondria, boosting ATP production and triggering a cascade of anti-inflammatory and tissue-repair signaling. For eczema specifically, it can:

• Reduce localized inflammation
• Accelerate wound healing in cracked, fissured skin
• Modulate immune cell activity
• Improve blood flow to affected areas

Clinical data specifically for eczema is still limited to small studies, while the evidence for red light therapy in wound healing and general skin inflammation is more developed. Many patients report improvement in skin texture, reduced itch, and faster healing of flare sites. At-home devices have made this approach more accessible, though quality and power output vary widely between products. Clinic sessions are typically cash pay. The red light therapy treatment guide covers wavelengths and session plans, and the national red light therapy clinic list shows which providers offer it.

Evidence: Emerging

Other Supplements and Approaches Worth Knowing About

How Do Eczema Treatments Compare?

Eczema treatments fall into three groups: daily barrier care for everyone, FDA-approved prescription medicines matched to severity, and add-on functional approaches with smaller evidence bases. Most people with mild eczema need only the first two steps of the ladder, while moderate to severe atopic dermatitis often calls for phototherapy, a biologic or an oral JAK inhibitor.

Does insurance cover eczema treatment?

Insurance usually covers dermatology visits, prescription creams, phototherapy and, after prior authorization, biologics and JAK inhibitors for moderate to severe atopic dermatitis. Functional medicine consultations, specialty lab panels, supplements and red light therapy sessions are usually cash pay. Ask any clinic for a written fee list before you book, because pricing varies widely and is rarely posted.

Building Your Eczema Management Plan

The best approach to eczema combines multiple strategies tailored to your specific situation. Here is a framework to think about it:

How to Calm an Eczema Flare at Home

Most mild flares respond to the same few steps done consistently. The order below follows the logic dermatologists use: cool the skin, treat the inflammation, seal the barrier, then remove the trigger.

1. Soak and seal. Take a 5 to 10 minute lukewarm bath or shower, pat dry, and apply any prescribed cream to the flare, then a thick layer of fragrance-free moisturizer to everything else within three minutes.
2. Use your anti-inflammatory as prescribed. A topical steroid or steroid-free cream applied once or twice daily to active patches works faster than moisturizer alone. Step down once the skin is smooth again.
3. Try a wet wrap for bad nights. A damp layer of cotton over moisturizer, with a dry layer on top, cools the skin and helps creams absorb. Ask your clinician before wrapping over a steroid.
4. Interrupt the scratch. Keep nails short, press or pinch instead of scratching, and use cool compresses. Cotton gloves at night help children and adults alike.
5. Find and remove the trigger. Check your trigger diary for new soaps, fragrance, wool, sweat, illness or stress in the days before the flare.
6. Watch for infection. Yellow crusts, pus, spreading pain, fever or clusters of punched-out blisters need a same-day visit, because bacterial infection and eczema herpeticum need prescription treatment.

Dilute bleach baths are another option some dermatologists recommend for people with frequent skin infections. Use them only with your clinician's exact recipe and frequency.

When to See a Specialist

You should see a dermatologist or allergist if:

• Your eczema is not responding to over-the-counter treatments after 2-4 weeks
• Flares are becoming more frequent or severe
• You have signs of skin infection (increased redness, warmth, pus, fever, or painful swelling)
• Eczema is significantly affecting your sleep, work, or mental health
• You are using topical steroids frequently and want to explore steroid-sparing alternatives
• You suspect a food allergy or contact allergy is contributing
• You are an adult with new-onset eczema (this sometimes signals an underlying condition that needs evaluation)

Consider seeing a functional medicine practitioner if you want to explore the gut-health connection, identify hidden food sensitivities through a structured elimination protocol, optimize your nutritional status, or take a more root-cause oriented approach alongside your conventional treatment plan.

Who Treats Eczema, and How Do You Find a Clinic?

Board-certified dermatologists diagnose and treat eczema and prescribe phototherapy, biologics and JAK inhibitors. Allergists and immunologists run patch, skin prick and IgE testing, pediatric dermatologists see children with severe disease, and primary care clinicians handle most mild cases. Functional and integrative medicine physicians, naturopathic doctors and registered dietitians work on gut health, diet and nutrient status alongside that care.

The eczema treatment clinic directory lists providers across the US who offer eczema care, from integrative dermatology to functional medicine. State lists such as eczema clinics in Maryland and eczema clinics in Indiana narrow the search.

How should you read the clinic list?

Listing order on Regenerated.com is not paid ranking, and clinics cannot buy a higher organic position. Featured slots are clearly labeled and capped in number. Verified means the clinic completed our claim and credential checks, not that it spent money with us. The directory is free for patients, and inclusion is not an endorsement. The guide to Featured, Verified and organic listings explains each label in full.

What should you ask an eczema clinic before booking?

• Who will I see, and what is their license and board certification?
• Do you work with my dermatologist or primary care clinician and share notes?
• Which tests do you order, and are they validated for eczema?
• Which treatments are FDA approved for eczema, and which are off label or supplements?
• What does the first visit cost, and what is billed to insurance versus cash pay?

Living with Eczema: The Mental Health Piece

This often gets overlooked, but it should not. Eczema is not “just a skin condition.” Studies consistently show that people with moderate-to-severe eczema have higher rates of depression, anxiety, and social isolation. The itch disrupts sleep. The visible skin changes affect self-esteem. The chronic nature of the disease wears people down.

If eczema is affecting your mental health, that is a valid and legitimate reason to seek support. Cognitive behavioral therapy (CBT) has shown benefit for itch management and coping. Some patients also benefit from habit-reversal training to break the scratch cycle.

You deserve to be treated as a whole person, not just a collection of symptoms.

Eczema in Children: Special Considerations

Most eczema starts before age five. In infants and young children, a few things are worth highlighting:

• Early and aggressive moisturization in high-risk newborns (those with a family history of atopic disease) may help prevent eczema from developing in the first place. A 2014 study in the Journal of Allergy and Clinical Immunology showed a 50% reduction in eczema incidence with daily emollient use from birth. Larger trials since then did not confirm it: the BEEP trial of 1,394 high-risk infants (Chalmers et al., The Lancet, 2020) found no evidence that daily emollient in the first year prevents eczema, and some evidence of more skin infections. Moisturizing a baby with dry skin is still good care; it is simply not a reliable prevention strategy.
• The “atopic march”: Children who develop eczema early are at higher risk for developing food allergies, asthma, and hay fever later. Early and effective eczema control may help interrupt this progression. The LEAP trial (Du Toit et al., New England Journal of Medicine, 2015) found that introducing peanut early to high-risk infants, including those with severe eczema, sharply lowered peanut allergy, so ask your pediatrician or allergist about early allergen introduction.
• Food allergy testing is more commonly warranted in young children with moderate-to-severe eczema, especially if flares seem connected to feeding.
• Bathing practices matter: The “soak and seal” approach (a 10-minute lukewarm bath followed immediately by emollient application) can be very effective for hydrating and protecting the skin.

Infant eczema usually starts on the cheeks, scalp and outer limbs and spares the diaper area. Use the mildest effective medicine, check with your pediatrician before any supplement, and see the guide to eczema in babies for age-specific care.

Frequently Asked Questions About Eczema

Is eczema contagious?

No. Eczema is not contagious, so you cannot catch it from someone else or spread it by touch. It comes from a mix of genetic susceptibility, a weak skin barrier and an overactive immune response. The exception is infection on top of eczema: if broken skin becomes infected with bacteria such as staph or a virus such as herpes simplex, that infection can spread, which is why weeping or crusted patches need a prompt visit.

Does eczema ever go away for good?

Atopic dermatitis is a chronic condition with no permanent fix today, but it often quiets down for long stretches. Many children outgrow it or see it fade by adolescence, and adults can reach long periods of remission with steady barrier care and the right medicine. The realistic goal is clear or nearly clear skin with little effect on sleep and daily life, and newer biologics and JAK inhibitors make that reachable for more people with severe disease.

Should I get allergy tested?

Allergy testing helps some people with eczema, not everyone. For children under five with moderate to severe eczema that does not respond to treatment, skin prick tests or specific IgE blood tests for common food allergens can be useful. For adults, patch testing for contact allergens such as nickel, fragrance and preservatives is more often helpful, especially when the rash has an unusual pattern. Avoid IgG food sensitivity panels, which are not validated and often produce misleading results.

Are topical steroids safe for long-term use?

Topical steroids carry low risk when used as directed: the right potency for the body area, short courses of usually one to two weeks for a flare, then a step down to twice-weekly maintenance or a steroid-free cream. Skin thinning and stretch marks mostly follow months of daily potent use, especially on the face and in skin folds. If you need frequent courses, ask about steroid-sparing options such as tacrolimus, crisaborole, roflumilast or a systemic medicine.

Does stress really make eczema worse?

Yes. Psychological stress activates the hypothalamic-pituitary-adrenal (HPA) axis and releases cortisol, neuropeptides and other mediators that weaken the skin barrier and push the immune system toward Th2 inflammation. Many patients can link their worst flares to stressful life events, and poor sleep from itching adds to the load. Stress management, including exercise, sleep routines, cognitive behavioral therapy and habit-reversal training, is a legitimate part of eczema treatment rather than an optional extra.

What is the best moisturizer for eczema?

The best moisturizer for eczema is a fragrance-free one you will use every day. Plain petrolatum ointments give the strongest barrier protection, and ceramide-containing creams help restore the lipids the skin barrier lacks. Skip products with fragrance, essential oils or long ingredient lists, which can irritate or sensitize the skin. Apply a generous layer at least twice daily and within three minutes of bathing, while the skin is still slightly damp, for the best absorption.

Can probiotics help my eczema?

Probiotics have their strongest support in prevention: given to pregnant and breastfeeding mothers and their infants, they lowered eczema risk in several studies. For existing eczema, a 2018 Cochrane review found they probably make little or no difference on average, though some people notice improvement. If you try them, choose a studied strain such as Lactobacillus rhamnosus GG or a multi-strain formula of at least 1 billion CFU, and allow 8 to 12 weeks before judging the result.

Is Dupixent worth it?

For adults and children with moderate to severe atopic dermatitis that topical treatment has not controlled, Dupixent (dupilumab) is often worth discussing with a dermatologist. In clinical trials, roughly 40 to 50% of patients reached at least 75% improvement in their eczema scores at 16 weeks. The most common side effects are injection site reactions and conjunctivitis. It is expensive without insurance, but most plans cover it after prior authorization, and the manufacturer runs a copay assistance program.

Can you develop eczema as an adult?

Yes. Adult-onset atopic dermatitis is more common than once thought, and some studies suggest it may account for up to 25% of adult cases. It often looks different from childhood eczema, favoring the hands, eyelids, head and neck. Anyone who develops a new eczema-like rash as an adult should see a dermatologist, because allergic contact dermatitis, psoriasis, scabies and cutaneous T-cell lymphoma can look similar and need to be ruled out.

How does red light therapy work for eczema?

Red light therapy, or photobiomodulation, uses red (630 to 660 nm) and near-infrared (810 to 850 nm) light that mitochondria absorb, raising cellular energy (ATP), lowering oxidative stress and switching on anti-inflammatory signaling. For eczema, the aim is calmer inflammation and faster healing of cracked skin. Evidence specific to eczema is still limited to small studies, so treat it as an add-on. Choose FDA-cleared devices with adequate power output, about 30 to 100 mW/cm².

Where can I find an eczema treatment clinic near me?

Regenerated.com lists eczema care providers across the US in a free national eczema clinic directory, with state pages that narrow the search. Listing order is not paid ranking, Featured slots are labeled and capped, and Verified means credential checks rather than spend. Inclusion is not an endorsement, so confirm each clinician's license, board certification, testing approach and fees before booking, and keep your dermatologist in the loop.

The Bottom Line

Eczema is a complex, chronic condition. But it does not have to run your life.

The treatment options available today are better than they have ever been. From advanced biologics that can control severe disease to functional medicine strategies that address the gut-skin connection, you have more tools at your disposal than any previous generation of eczema patients.

The most successful approach combines consistent skin barrier care with targeted anti-inflammatory treatments and root-cause strategies like optimizing vitamin D, supporting gut health, managing stress, and identifying personal triggers.

Work with a healthcare team that listens, take a multi-layered approach, and be patient with the process. Skin healing takes time. But improvement is possible, and for many people, clear or nearly clear skin is a realistic goal to work toward. When you are ready for help, you can browse eczema clinics by state and compare dermatology and functional medicine options side by side.
