Eczema has no permanent cure, but it can be managed well enough that some people go months or even years without a flare. It’s a chronic, relapsing condition driven by a combination of immune system overactivity and a compromised skin barrier. The goal of treatment is long-term remission: fewer flares, less itching, and healthier skin between episodes. Most people achieve this through layered strategies, starting with daily skin care and escalating to prescription treatments when needed.
Why Eczema Can’t Be “Cured” Yet
Eczema (atopic dermatitis) is rooted in how your immune system responds to irritants and allergens, combined with genetic differences in your skin’s ability to retain moisture. People with eczema typically produce less of the proteins that keep the outer skin barrier intact, which lets irritants in and moisture out. Because these tendencies are built into your biology, no treatment eliminates the underlying condition. What treatments do is interrupt the cycle of inflammation, itch, and damage so your skin can heal and stay calm for longer stretches.
Daily Skin Care That Actually Matters
The single most effective habit for eczema is consistent moisturizing, and the timing matters more than the brand. After bathing in lukewarm water, you have roughly three minutes to apply moisturizer before your skin starts losing the water it just absorbed. This “soak and seal” technique traps hydration in the skin and strengthens the barrier. Thick ointments and creams work better than lotions because they contain more oil and less water.
Bathing itself should be brief, around 10 to 15 minutes, and with gentle, fragrance-free cleansers only on areas that need them (armpits, groin, feet). Hot water strips natural oils from the skin and can trigger itching within minutes.
Bleach Baths
Dilute bleach baths reduce the load of Staphylococcus aureus bacteria that colonize eczema-prone skin and drive inflammation. The Mayo Clinic recommends adding one-quarter cup of regular household bleach to a 20-gallon bathtub of warm water, or half a cup for a full tub. You soak from the neck down for 5 to 10 minutes, once or twice a week. The concentration is similar to a swimming pool, so it shouldn’t sting healthy skin, though open cracks or wounds may be sensitive at first.
Coconut Oil as a Moisturizer
Virgin coconut oil has genuine evidence behind it. In a study of adults with eczema, 95% of those who applied virgin coconut oil cleared Staph aureus from their skin, compared to only 50% using virgin olive oil. Coconut oil contains a fatty acid that breaks down into monolaurin, a compound with broad antimicrobial activity. It works as both a moisturizer and a mild antimicrobial, making it a reasonable option for daily use, though it’s not potent enough to replace prescription treatments during active flares.
Wet Wrap Therapy for Severe Flares
When eczema is flaring badly, wet wrap therapy can deliver dramatic relief. The process involves applying your prescribed cream or ointment to affected skin, then coating everything with a thick layer of plain moisturizer. You then put on a layer of damp (not dripping) cotton clothing, followed by a dry layer on top. The moisture slowly evaporates over a few hours, cooling the skin and driving the medication deeper into inflamed areas. This is especially useful for children during intense flares and is typically done under the guidance of a dermatologist who specifies which topical treatments to use underneath.
Topical Steroids: The First-Line Prescription
Topical corticosteroids remain the backbone of eczema treatment during flares. They’re ranked on a seven-class potency scale, from Class VII (mildest, like over-the-counter hydrocortisone 1%) up to Class I (strongest, prescription-only). Your doctor matches the potency to the severity and location of your eczema. Thin skin on the face, eyelids, and skin folds gets the mildest options. Thick, stubborn patches on hands or feet may need something from Class I or II.
The common fear with steroids is skin thinning, and that’s a real concern with prolonged use of potent formulations. But short bursts during flares, followed by stepping down to a milder steroid or switching to a non-steroidal option, is the standard approach and is safe for most people. Some dermatologists prescribe a low-potency steroid two to three times per week on areas prone to relapse, even when the skin looks clear, to prevent the next flare before it starts.
Non-Steroid Prescription Options
For people who need long-term control without the side effects of steroids, several newer options exist. Topical calcineurin inhibitors (tacrolimus and pimecrolimus) calm the immune response in the skin without causing thinning and are safe for sensitive areas like the face and eyelids.
A newer class of topical treatment works by blocking specific enzymes called JAK proteins that transmit inflammatory signals inside skin cells. Topical ruxolitinib cream, approved for patients 12 and older, selectively blocks two of these enzymes and provides both anti-inflammatory and anti-itch effects. In clinical trials, it reduced eczema severity significantly compared to a vehicle cream, and because it’s applied directly to the skin, systemic side effects are minimal.
Biologics and Oral Treatments for Moderate to Severe Eczema
When topical treatments aren’t enough, injectable biologics and oral medications can target the immune dysfunction driving eczema from the inside. Dupilumab, a biologic injection given every two weeks, blocks two key inflammatory signals and has become a cornerstone treatment for moderate to severe eczema in both adults and children. Many patients see 75% or greater skin clearance within 16 weeks.
Oral JAK inhibitors like upadacitinib and abrocitinib offer another systemic option, taken as a daily pill. These work fast, often producing noticeable itch relief within the first few days. They do carry more potential side effects than biologics, including increased infection risk and changes in blood counts, so they require regular monitoring. Additional biologics targeting different inflammatory pathways, such as tralokinumab and lebrikizumab, have expanded the options for people who don’t respond to the first treatment they try.
Phototherapy
Narrowband UVB phototherapy uses a specific wavelength of ultraviolet light to calm the immune response in the skin. It typically requires two to three sessions per week at a clinic, and most people need several weeks of treatment before seeing meaningful improvement. Studies in children with eczema have shown greater than 60% reduction in severity scores, and more than half of patients who achieve clearance maintain it for at least 12 months. It’s a good option for people with widespread eczema who want to minimize medication use, though the time commitment of clinic visits is a practical barrier for many.
Do Elimination Diets Help?
The idea that cutting out dairy, eggs, gluten, or other common allergens will clear up eczema is widespread but only weakly supported by evidence. A meta-analysis of 10 randomized controlled trials found that dietary elimination may slightly improve eczema severity: 50% of people on elimination diets improved by a clinically meaningful amount, compared to 41% who improved without any dietary changes. That 9-percentage-point difference is real but small, and the researchers described it as “potentially unimportant” for most patients with mild to moderate eczema.
Interestingly, it didn’t seem to matter whether the elimination was guided by allergy testing or done empirically. If you suspect a specific food triggers your flares, a structured elimination trial (removing it completely for 4 to 6 weeks, then reintroducing it) is the most reliable way to test. But broadly cutting out multiple food groups without clear evidence of a trigger is unlikely to produce a noticeable difference and can lead to nutritional gaps, especially in children.
Skin Microbiome Treatments on the Horizon
One of the more promising areas of research involves replacing harmful bacteria on eczema-prone skin with beneficial ones. A phase I/II trial tested a topical spray containing live Roseomonas mucosa, a bacterium naturally found on healthy skin, in 15 adults and children with eczema. Two-thirds of participants achieved a greater than 50% improvement in eczema severity scores, and the treatment also reduced Staph aureus colonization and the need for topical steroids. The approach works on multiple levels: strengthening the skin barrier, rebalancing the immune response, and suppressing the harmful bacteria that fuel flares. Larger trials are still needed, but this represents a fundamentally different strategy from suppressing the immune system, one that aims to restore the skin’s natural ecosystem instead.
