Eczema can’t be permanently cured, but it can be controlled well enough that your skin stays clear for long stretches. The strategy depends on severity: mild eczema often responds to consistent moisturizing and trigger avoidance alone, while moderate to severe cases typically need prescription creams, light therapy, or newer systemic medications. The core principle is the same at every level: repair your skin barrier, reduce inflammation, and stop the cycle of itching and damage.
Fix the Skin Barrier First
Eczema-prone skin is missing key fats, especially ceramides, that normally keep the outer layer sealed and hydrated. Without them, water escapes, irritants get in, and inflammation follows. This is why moisturizing isn’t just a comfort measure. It’s the foundation of every eczema treatment plan, recommended as first-line care by the American Academy of Dermatology regardless of how severe your condition is.
Not all moisturizers work the same way. The three categories that matter are humectants (which pull water into the skin), occlusives (which form a physical seal to trap moisture), and ceramide-based formulas (which actually replace the missing fats in your skin’s structure). Ceramide-dominant moisturizers go beyond surface protection. They integrate into the outer skin layer, help normalize skin pH, and restore antimicrobial defenses that eczema disrupts. Petrolatum (plain petroleum jelly) is the simplest and most effective occlusive, forming a barrier that prevents water loss and blocks irritants.
Apply moisturizer within a few minutes of bathing, while skin is still slightly damp. This locks in significantly more hydration than applying to dry skin. Reapply at least once more during the day, and use fragrance-free products exclusively.
Identify and Remove Your Triggers
Eczema flares don’t happen randomly. They’re usually provoked by something your skin or immune system reacts to. Common culprits include soaps, detergents, fragrances, solvents, and ingredients in skincare products. Wool and synthetic fabrics irritate many people with eczema, while cotton and cotton blends tend to be tolerated well. Even new clothing contains formaldehyde and other chemicals that can trigger a flare, so wash everything before wearing it. If clothing labels or seams bother you, cut the labels out or wear clothes inside-out at home.
Environmental allergens play a role too: dust mites, pet dander, cockroach debris, pollen, and mold can all worsen symptoms. Temperature extremes are another reliable trigger. High humidity and sweating irritate eczema-prone skin, while low humidity pulls water out of the skin and causes dryness. Keeping indoor humidity between 30% and 50% and avoiding overheating (especially at night) helps many people reduce flare frequency.
Topical Steroids for Active Flares
When moisturizing and trigger avoidance aren’t enough, topical corticosteroids are the standard next step. These creams and ointments reduce inflammation quickly and are grouped into seven potency classes, from mild hydrocortisone (available over the counter at 1% strength) up to very potent prescription formulas. Your doctor will match the strength to the location and severity of your eczema. Thicker skin on hands and feet can handle stronger steroids, while the face, neck, and skin folds need milder ones.
The goal is to use the lowest potency that controls your symptoms for the shortest time needed. Most flares respond within one to two weeks of consistent application. Ointments generally work better than creams because they provide an occlusive layer on top of the medication, keeping it in contact with the skin longer.
Steroid-Free Prescription Creams
Several non-steroid topical options now exist for people who need long-term treatment or want to avoid steroid side effects on sensitive areas like the face. Calcineurin inhibitors calm the immune response in the skin without thinning it, making them useful for maintenance therapy. Newer options include creams that block specific inflammatory enzymes (PDE-4 inhibitors and JAK inhibitors), which the AAD strongly recommends for managing atopic dermatitis. Tapinarof cream, one of the most recently approved options, works through a different pathway altogether and has shown strong results in clinical guidelines.
These medications are particularly valuable for the face, eyelids, and groin, where long-term steroid use carries real risks of skin thinning and other complications.
Bleach Baths and Wet Wraps
Two home-based techniques can make a noticeable difference, especially during bad flares. Bleach baths sound harsh, but the concentration is very dilute: one-quarter cup of regular household bleach in a 20-gallon tub of warm water, or half a cup in a full tub. If your bleach has a higher sodium hypochlorite concentration (up to 8.25%), use a bit less. Soak the affected areas for 5 to 10 minutes. This reduces the bacterial load on eczema-prone skin, since Staph bacteria commonly colonize broken skin and drive inflammation.
Wet wrap therapy is more intensive and works well for severe flares, especially in children. The process starts with a 15-minute lukewarm bath, followed by gently patting skin mostly dry while it’s still damp. Topical medication goes on first, then a generous layer of unscented moisturizer. Next, damp clothing or wet gauze covers the treated areas, trapping the medication and moisture against the skin. Dry clothes go over the top for warmth. The wrap stays on for about two hours, or overnight in severe cases. This approach can be repeated up to three times a day during acute flares.
Light Therapy for Widespread Eczema
When eczema covers large areas of the body, applying creams everywhere becomes impractical. Narrowband UVB phototherapy treats the whole body at once by exposing skin to a specific wavelength of ultraviolet light that calms the immune response. Sessions happen two to three times per week (once weekly doesn’t work), and most people need between 10 and 40 treatments to see significant clearing. Twice-weekly sessions are less effective than three times weekly, so consistency matters.
Phototherapy requires regular trips to a dermatologist’s office or phototherapy clinic, which is the main drawback. But for people with moderate to severe eczema who want to avoid systemic medications, it’s a well-established option with a long safety record.
Systemic Treatments for Severe Cases
If topical treatments and light therapy aren’t controlling your eczema, injectable or oral medications that work from the inside are the next tier. The biggest shift in eczema treatment over the past decade has been the arrival of biologic injections that target specific immune signals driving the disease. Dupilumab was the first, and several others have since been approved. These block the specific inflammatory messengers (primarily interleukins 4 and 13) that are overactive in eczema, rather than suppressing the entire immune system.
Oral JAK inhibitors are another option, with two (abrocitinib and upadacitinib) now FDA-approved for eczema. These work more broadly, blocking multiple inflammatory pathways at once, and tend to work fast. They come with more monitoring requirements than biologics because of their wider immune effects, but they offer an alternative for people who don’t respond to or prefer not to use injections.
One notable recommendation from the AAD: systemic corticosteroids (like prednisone pills) are recommended against for eczema management. While they provide quick temporary relief, they cause rebound flares when stopped and carry serious long-term risks. If you’ve been prescribed oral steroids repeatedly for eczema, it’s worth asking about the newer targeted therapies instead.
What About Elimination Diets?
Many people with eczema wonder whether cutting certain foods will clear their skin. The evidence is underwhelming. A systematic review of 10 randomized trials involving 599 participants found that dietary elimination led to, at best, a slight improvement in eczema severity. About 50% of people on elimination diets saw meaningful improvement, compared to 41% without any dietary changes. That 9 percentage point difference was classified as “potentially unimportant” by the researchers.
More concerning, indirect evidence suggests that elimination diets may actually increase the risk of developing true food allergies, particularly in children. This is because regular exposure to foods helps the immune system learn to tolerate them. If you suspect a specific food triggers your flares, working with an allergist to test and confirm the allergy is safer than cutting out foods on your own, and it avoids the risk of unnecessary dietary restriction delaying more effective treatments.
Building a Long-Term Routine
Eczema management works best as a layered daily routine rather than a reactive scramble during flares. The base layer is consistent moisturizing, at minimum twice daily and always after bathing. On top of that, a mild non-steroid prescription cream can be used on flare-prone areas a few times per week as maintenance, even when skin looks clear. Topical steroids stay in reserve for actual flares, applied for short bursts until the skin calms. Trigger avoidance runs in the background at all times: fragrance-free laundry detergent, cotton clothing, controlled indoor humidity, and regular dusting to manage dust mites.
This proactive approach, sometimes called “proactive therapy,” reduces flare frequency significantly compared to only treating symptoms after they appear. The goal isn’t perfection. It’s keeping your skin barrier intact enough that minor exposures don’t snowball into full flares.
