How to Treat Eczema: Moisturizers, Steroids & More

Eczema treatment works in layers: consistent moisturizing forms the foundation, medicated treatments control flares, and trigger avoidance keeps symptoms from returning. Most people with mild to moderate eczema can manage it well with over-the-counter moisturizers and low-strength topical steroids, while moderate to severe cases may need prescription creams, light therapy, or newer injectable medications that target the immune system.

Moisturizing Is the Single Most Important Step

Every eczema treatment plan starts with moisturizing, and doing it consistently matters more than which product you pick. A good moisturizer does three things: it slows water loss from your skin, helps your skin hold onto moisture, and reduces friction that can trigger irritation. Look for products that combine occlusive ingredients (like petrolatum, mineral oil, or lanolin) with humectants (like glycerin) to cover both functions.

Ceramide-based moisturizers deserve special attention. Ceramides are fat molecules that naturally exist in your outer skin layer and maintain the skin barrier. People with eczema have lower ceramide levels, which is why their skin loses water faster and lets irritants in more easily. Moisturizers containing ceramides or synthetic versions called pseudoceramides can help restore that barrier and may also reduce inflammation.

Aim to apply moisturizer two to three times per day, and always within a few minutes of bathing while your skin is still slightly damp. Fragrance-free, plain creams or ointments work best. One important note: aqueous cream (sometimes labeled “Aqueous Cream BP”) should not be used as a leave-on moisturizer for eczema, as it can actually worsen the condition.

Topical Steroids for Flares

When moisturizing alone isn’t enough to control redness, itching, and inflammation, topical corticosteroids are the standard first-line treatment. These come in seven potency classes in the U.S., ranging from class VII (least potent, like over-the-counter hydrocortisone 1%) up to class I (superpotent prescription creams). Your doctor will match the strength to the severity of your flare and the location on your body. Thicker skin on elbows and knees can handle stronger formulations, while the face, neck, and skin folds need milder ones.

A useful way to gauge how much to apply is the fingertip unit, where one FTU equals about half a gram of cream squeezed from the tip of your index finger to the first crease. For a single application, the face and neck need about 2.5 FTUs, one arm needs 3 FTUs, and the front or back of your torso each need about 7 FTUs. Using the right amount matters: too little won’t work, and too much increases the risk of skin thinning over time.

Steroid-Free Prescription Creams

For people who need ongoing treatment in sensitive areas like the face or eyelids, or who worry about long-term steroid side effects, several non-steroidal prescription options exist. Tacrolimus and pimecrolimus are calcineurin inhibitors that work by blocking the activation of immune cells in the skin, reducing the inflammatory signals that drive eczema. They don’t cause skin thinning, which makes them especially useful for the face and neck.

Crisaborole is a newer topical option that works differently. It blocks an enzyme called PDE4, which raises levels of a signaling molecule inside skin cells that dials down inflammation. It’s a mild to moderate treatment, best suited for people whose eczema isn’t severe enough to warrant stronger options. A topical form of a JAK inhibitor (ruxolitinib) is also approved in the U.S. for patients 12 and older, offering another steroid-free alternative that works by interrupting the itch and inflammation cycle at a deeper level.

Wet Wrap Therapy for Severe Flares

When a flare is intense and widespread, wet wrap therapy can deliver faster relief by locking medication and moisture against the skin for an extended period. The process starts with soaking in a lukewarm bath for about 15 minutes. After bathing, pat the skin mostly dry, leaving it slightly damp, then apply prescribed topical medication to affected areas and follow with a generous layer of unscented moisturizer.

Next, cover the treated skin with clothing or gauze that has been soaked in warm water. Put dry clothes or blankets over the wet layer to stay warm. The wrap stays on for about two hours, or overnight in severe cases. This is typically done up to three times a day during bad flares. In cases where skin infections are a concern, dilute bleach can be added to the soaking bath.

Bleach Baths to Prevent Infection

Broken, scratched eczema skin is a magnet for bacteria, particularly Staph aureus, which can trigger worsening flares and infection. Dilute bleach baths help reduce bacterial load on the skin. 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 standard tub. The resulting concentration is similar to a swimming pool. Soak for 5 to 10 minutes, rinse with plain water, and moisturize immediately after.

Light Therapy

Narrowband UVB phototherapy is an effective option for widespread eczema that isn’t responding well to creams alone. It involves standing in a light booth at a dermatologist’s office, ideally three times a week during the treatment phase. In one study, patients saw a 68% reduction in eczema severity scores after 12 weeks of thrice-weekly sessions. Once symptoms improve, the frequency can be reduced to a maintenance schedule. It’s a good middle ground for people who want to avoid systemic medications but aren’t getting enough relief from topicals.

Systemic Treatments for Moderate to Severe Eczema

When eczema covers large areas of the body or resists topical treatments, medications that work from the inside become necessary. Dupilumab, given as an injection every two weeks, blocks two key immune signals (IL-4 and IL-13) that drive the allergic inflammation behind eczema. It was the first biologic approved specifically for eczema and has transformed treatment for many people with moderate to severe disease. Tralokinumab is a similar injectable that specifically targets IL-13 alone.

Two oral JAK inhibitors, upadacitinib and abrocitinib, are approved in the U.S. for patients 12 and older. These pills work by blocking enzymes inside immune cells that transmit inflammatory signals, and they tend to work faster than biologics. They carry different safety considerations than biologics, so the choice between them depends on individual health factors.

Identifying and Avoiding Triggers

Treatment works best when paired with reducing whatever is provoking flares. The most common triggers fall into a few categories. Harsh detergents and soaps compromise the skin barrier and make it more reactive to other irritants. Tobacco smoke is one of the most significant indoor triggers. Volatile organic compounds from building materials, paint, and new furniture can provoke symptoms even at concentrations below official safety thresholds, especially in combination with house dust mite allergens.

Seasonal patterns vary by age. Children tend to flare more in fall and winter, when cold air and indoor heating dry out the skin. Adults often flare in summer, when heat and sweating increase itching and disrupt sleep. For people whose eczema concentrates on the head and neck, airborne allergens like pollen can be a significant driver during allergy season. Air pollution, including fine particulate matter, can penetrate deeper skin layers and weaken the skin barrier on its own.

What About Diet Changes?

Elimination diets are one of the most commonly asked-about eczema strategies, but the evidence for them is weak. A Cochrane review of nine randomized controlled trials found little support for food elimination diets in unselected eczema patients, and the American Academy of Dermatology does not recommend them as a general treatment. That said, if you have a confirmed food allergy diagnosed through proper testing, avoiding that specific food can help. The key distinction is between a true allergy and a blanket elimination diet done without testing.

Vitamin D supplementation has generated mixed results. Some small trials showed improvement in eczema symptoms, but they had significant limitations, including not using a placebo or studying only a narrow group of children with winter-related flares. Other trials found no benefit. The AAD currently says there isn’t enough data to recommend vitamin D supplements specifically for eczema, though allergy and immunology professional groups are more supportive. If you’re deficient in vitamin D, correcting that deficiency is reasonable, but it’s unlikely to be a standalone eczema treatment.
