Eczema can’t be permanently cured, but the right combination of daily skin care, trigger avoidance, and targeted treatments can keep flares minimal or even push symptoms into long stretches of remission. Most people with mild to moderate eczema gain control through consistent moisturizing and topical medications alone. For stubborn or severe cases, newer injectable and oral therapies now achieve 75% or greater skin clearance in roughly 9 out of 10 patients within a year.
Daily Moisturizing Is the Foundation
Everything else you do for eczema works better when your skin barrier is intact, and moisturizing is how you maintain it. Apply a fragrance-free cream or ointment within a few minutes of bathing, while skin is still slightly damp. This traps water in the outer layer of skin and reduces the microscopic cracking that lets irritants in and moisture out. Lotions (which are thinner and water-based) evaporate faster and generally aren’t enough for eczema-prone skin. Ointments like petroleum jelly provide the strongest barrier, though creams are a reasonable middle ground if you dislike the greasy feel.
Aim to moisturize at least twice a day, and reapply after hand washing or any time skin feels tight. This single habit reduces the frequency of flares and cuts down how much medicated treatment you’ll need over time.
Identifying and Avoiding Your Triggers
Eczema flares don’t happen randomly. They’re set off by specific irritants or allergens, and figuring out yours is one of the most effective long-term strategies. The most well-established triggers include house dust mites, pet dander, mold spores, fragrances, and harsh soaps or detergents.
Air pollution also plays a measurable role. Tobacco smoke, volatile organic compounds (chemicals released by paints, adhesives, and new flooring), formaldehyde, and traffic-related pollutants like nitrogen dioxide and carbon monoxide have all been linked to worsening eczema. One large survey of over 300,000 children found a clear association between traffic pollution exposure and eczema severity. Indoor remodeling activities, including painting, installing floor coverings, and wallpapering, have similarly been tied to flares.
Practical steps that help: wash bedding weekly in hot water to reduce dust mites, use fragrance-free laundry detergent, keep indoor humidity between 30% and 50%, and ventilate well during and after any home renovation work. If you suspect pet dander, keeping animals out of the bedroom is a reasonable first step before considering allergy testing.
Topical Steroids: Matching Strength to Location
Topical corticosteroids remain the most commonly prescribed treatment for active eczema flares. They come in seven potency classes, from ultra-high (Class I) down to least potent (Class VII), and the right choice depends on where on your body the eczema is and how severe it is.
Low-potency steroids are safest for the face, groin, armpits, and anywhere skin is thin, as well as for use on children and over large areas of the body. Stronger formulations work better on thick-skinned areas like the palms and soles, or for stubborn patches that don’t respond to milder options. High and ultra-high potency steroids should not be used on the face, groin, or armpits except briefly and under close medical supervision.
Once- or twice-daily application is the standard recommendation. Applying more frequently doesn’t produce better results. Most dermatologists advise using a steroid until the flare clears, then stepping down to moisturizer alone or a non-steroidal maintenance treatment rather than continuing steroids indefinitely.
Non-Steroidal Topical Options
If you’re concerned about long-term steroid use, or if you need ongoing treatment on sensitive areas like the face and eyelids, non-steroidal topicals offer an alternative. The two main categories are calcineurin inhibitors and PDE-4 inhibitors, and they differ substantially in how well they work.
Tacrolimus 0.1% (a calcineurin inhibitor) consistently ranks among the most effective topical treatments for eczema, performing on par with potent steroids in large analyses. It’s particularly useful for facial eczema and as a long-term maintenance option. A common side effect is a burning or stinging sensation when first applied, which typically fades after the first week of use.
PDE-4 inhibitors like crisaborole rank among the least effective topical anti-inflammatory treatments in head-to-head comparisons. They may help with very mild eczema but generally aren’t strong enough for moderate or severe disease. If you’ve tried one and found it underwhelming, that’s consistent with the clinical evidence.
Bleach Baths and Wet Wraps
People with eczema carry higher levels of certain bacteria on their skin, which can drive inflammation and infection. Dilute bleach baths help reduce that bacterial load. The Mayo Clinic recommends adding one-quarter cup of regular household bleach to a 20-gallon tub of warm water (or half a cup to a full tub), then soaking from the neck down for 5 to 10 minutes. This creates a concentration similar to a swimming pool. Rinse afterward and apply moisturizer immediately.
Wet wrap therapy is a more intensive technique for severe flares. The process starts with a 15-minute lukewarm bath, followed by gently patting skin mostly dry, applying prescribed topical medication, then layering on a generous coat of unscented moisturizer. Next, damp clothing or wet gauze is placed over the treated skin, followed by a dry layer on top. The wrap stays on for about two hours, or overnight in severe cases. The prolonged moisture contact helps topical medications penetrate the outer skin layer far more effectively than applying them to dry skin. This approach is used up to three times daily during bad flares and can bring dramatic improvement within days.
When Topicals Aren’t Enough
For moderate to severe eczema that doesn’t respond adequately to topical treatment, several systemic therapies are now available. The most significant development in recent years is dupilumab, an injectable biologic that targets specific immune signals driving eczema inflammation. In a study of over 2,500 patients tracked in real-world clinical practice, 88.8% achieved at least 75% skin clearance after one year, and 90.9% maintained that level at four years. It’s given as an injection every two weeks and has a relatively favorable safety profile.
Oral JAK inhibitors (upadacitinib and abrocitinib are the ones used for eczema) work faster than biologics, with some patients noticing improvement within days. However, the FDA requires their strongest safety warning on these medications due to potential increased risks of serious cardiovascular events, blood clots, and cancer observed in studies of a related drug. These risks appear most relevant for people over 50 with existing heart disease risk factors, but they’re part of the conversation when weighing options.
Older systemic options like cyclosporine, methotrexate, and phototherapy (controlled UV light exposure) are still used when newer treatments aren’t accessible or appropriate. Notably, oral corticosteroids (like prednisone) are recommended against for eczema management because flares typically rebound worse once the course ends.
The Role of Diet
Many people with eczema wonder whether cutting certain foods will help. The honest answer: it depends entirely on whether you actually have a food allergy. Roughly 30% to 40% of children with moderate to severe eczema do have a specific food allergy, most commonly to eggs, milk, peanuts, or wheat. For those children, eliminating the confirmed allergen can meaningfully reduce flares.
But broadly cutting out foods without evidence of allergy doesn’t work. Studies of blanket elimination diets, where people remove multiple food groups at once, fail to show significant improvement in patients without a confirmed allergy. Isolated skin reactions to food challenges are uncommon, occurring in only about 6% of cases in controlled testing. If you suspect a food trigger, allergy testing (skin prick or blood test) is a far better approach than guessing and restricting your diet unnecessarily, which can lead to nutritional gaps without any skin benefit.
Building a Routine That Works
The people who manage eczema most successfully treat it as an ongoing routine rather than reacting to flares after they’ve started. That routine typically looks like this: gentle fragrance-free cleanser in the bath or shower (lukewarm, not hot), moisturizer applied within minutes of drying off, a non-steroidal maintenance treatment on areas prone to flaring, and a topical steroid kept on hand for breakthrough flares. Trigger avoidance becomes second nature over time.
The goal isn’t perfection. It’s reducing flare frequency, shortening the ones that do happen, and keeping skin comfortable enough that eczema stops dictating your daily decisions. For most people, that goal is realistic with the treatments available today.
