The single best thing for eczema is consistent, daily moisturizing with a thick, fragrance-free cream or ointment, ideally one containing ceramides or petrolatum. That alone won’t cure eczema, but it addresses the root problem: a leaky skin barrier that lets moisture escape and irritants sneak in. Beyond moisturizing, the “best” approach depends on your severity, combining trigger avoidance, the right topical treatments, and sometimes prescription therapies into a layered strategy.
Why Moisturizing Matters More Than Anything Else
Eczema skin loses water at a dramatically higher rate than healthy skin. The outer layer is supposed to act like a brick wall, with skin cells as the bricks and natural fats (lipids) as the mortar. In eczema, that mortar is thin and cracked. Moisturizers work by filling those gaps or sealing water in, and the type you choose matters.
There are three categories worth understanding. Occlusives, like petrolatum (the main ingredient in Vaseline), sit on top of the skin and physically block water from escaping. Petrolatum is remarkably effective: at just a 5% concentration, it reduces water loss through the skin by more than 98%. Humectants, like glycerin and hyaluronic acid, pull water from deeper skin layers up toward the surface. And emollients, the lipid-based ingredients, smooth and soften by filling in the tiny cracks between skin cells.
The most effective eczema moisturizers combine all three, but the standout ingredient to look for is ceramides. Unlike petrolatum, which just sits on the surface, ceramides actually penetrate into the skin barrier and restore its natural waterproofing function. They’re one of the fats your skin is supposed to produce on its own but doesn’t make enough of when you have eczema. Look for fragrance-free creams or ointments listing ceramides in the first several ingredients. Apply within three minutes of bathing, while your skin is still slightly damp, to lock in that moisture.
Common Triggers That Make Flares Worse
Moisturizing rebuilds the barrier, but avoiding what damages it in the first place is equally important. The most common eczema triggers include fragrances (in soap, lotion, laundry detergent, and cleaning products), rough fabrics like wool, dry air, heat and sweat, dust mites, pet dander, pollen, mold, and tobacco smoke. Stress is also a reliable trigger for many people.
Switch to fragrance-free, dye-free, alcohol-free cleansers and detergents. Use lukewarm water instead of hot for bathing, and keep showers short. If dry indoor air is a problem, a humidifier in your bedroom can help. Figuring out your personal triggers often takes some trial and error, but eliminating fragrances from your routine is the single change most likely to make a noticeable difference.
Over-the-Counter Remedies Worth Trying
Colloidal oatmeal is one of the few natural ingredients with solid evidence behind it. It activates genes involved in skin barrier repair, lipid production, and the tight junctions that hold skin cells together. It also buffers skin pH, which matters because eczema-prone skin tends to be more alkaline than it should be, and that alkalinity encourages bacterial growth and inflammation. You can find colloidal oatmeal in lotions, bath soaks, and creams.
Virgin coconut oil is another option that does double duty as a moisturizer and antimicrobial. Eczema skin is frequently colonized by Staphylococcus aureus bacteria, which worsen inflammation and can cause infections. In one clinical trial, only 5% of people using virgin coconut oil still tested positive for staph after treatment, compared to 50% of those using virgin olive oil. That’s a meaningful difference. Apply it directly to damp skin, though be aware it doesn’t contain ceramides and works best as a supplement to a ceramide-based moisturizer rather than a replacement.
When to Step Up to Topical Steroids
If moisturizing and trigger avoidance aren’t enough to control flares, topical corticosteroids are the standard next step. These are anti-inflammatory creams and ointments that calm the immune overreaction driving your eczema. In the U.S., they’re classified into seven potency levels, from class VII (mildest, like over-the-counter hydrocortisone 1%) up to class I (superpotent, prescription only).
Over-the-counter hydrocortisone works for mild eczema on the body. For more stubborn patches, a doctor can prescribe medium or high-potency options. The key safety rule: don’t use any topical steroid continuously for longer than two to four weeks on the same area of skin. High-potency steroids specifically should be limited to two weeks before tapering. Extended use in one spot can thin the skin permanently. Sensitive areas like the face, eyelids, and skin folds need the mildest formulations. Your prescriber will match the potency to the location and severity.
Steroid-Free Prescription Alternatives
For eczema on the face, eyelids, or other sensitive areas where steroids are risky, two categories of steroid-free prescription topicals are available. Calcineurin inhibitors (tacrolimus and pimecrolimus) work by blocking the activation of immune cells that drive eczema inflammation. They’re approved for adults and children over two and are particularly useful for long-term maintenance in areas where you can’t safely use steroids.
A newer option targets a different pathway entirely. Crisaborole is an ointment that reduces inflammation by raising levels of a signaling molecule called cAMP inside skin cells, which dials down the production of inflammatory chemicals. It’s designed for mild to moderate eczema and is a good fit for people who want to avoid steroids altogether or need something for daily use on delicate skin.
Bleach Baths and Wet Wraps
Two at-home techniques can make a significant difference during flares, especially if your skin tends to get infected. Bleach baths use a very dilute solution (one-quarter cup of regular household bleach in a 20-gallon tub of warm water, or half a cup in a full tub) to reduce staph bacteria on the skin. Soak for about 10 minutes, once or twice a week. The concentration is similar to a swimming pool, so it’s gentler than it sounds, but rinse off afterward and moisturize immediately.
Wet wrap therapy is more intensive and works well for severe flares. The process starts with a 15-minute lukewarm bath, then patting skin mostly dry while leaving it slightly damp. Apply prescribed topical medication, followed by a generous layer of fragrance-free moisturizer. Then wrap the treated areas in warm, damp clothing or gauze, and cover that with a dry layer to hold in warmth. Wear the wrap for about two hours, or overnight for severe cases. The National Institute of Allergy and Infectious Diseases recommends soaking and wrapping up to three times daily during bad flares. This approach keeps medication in contact with the skin longer and dramatically boosts moisture absorption.
Light Therapy for Moderate to Severe Eczema
Narrowband UVB phototherapy uses a specific wavelength of ultraviolet light to calm the overactive immune response in the skin. It’s typically offered when topical treatments alone aren’t controlling symptoms. Sessions happen three times per week, and most people need 20 to 36 sessions before seeing significant clearing. That’s roughly two to three months of consistent visits to a dermatologist’s office or phototherapy clinic. It’s time-consuming but avoids the systemic side effects of oral medications, making it a good middle-ground option before escalating to stronger therapies.
Systemic Treatments for Severe Cases
When eczema doesn’t respond to topical treatments or phototherapy, oral and injectable medications can target the immune system more broadly. The newest class, JAK inhibitors taken as daily pills, have shown impressive results. In a major trial published in the New England Journal of Medicine, 70.3% of patients taking the higher dose of abrocitinib achieved at least a 75% improvement in their eczema severity score at 12 weeks, compared to 27.1% on placebo. Nearly half (48.4%) reached clear or almost clear skin.
These medications do require monitoring. JAK inhibitors can lower platelet counts, raise cholesterol levels, and carry other risks that need regular blood work to track. Injectable biologics that target specific inflammatory proteins are another option, generally with a different side effect profile. These systemic treatments are reserved for moderate to severe eczema that hasn’t responded to other approaches, and the choice between them involves balancing effectiveness, convenience, and your individual risk factors with your dermatologist.
Building a Layered Routine
The best approach to eczema isn’t a single product. It’s a layered system. Start with the foundation: daily ceramide-based moisturizing, fragrance-free products, and trigger avoidance. Add colloidal oatmeal baths or virgin coconut oil if you want natural support. Use topical steroids or steroid-free prescriptions for flares, keeping them short-term and targeted. Consider bleach baths if infections are recurring. And if none of that is enough, phototherapy and systemic medications offer real relief for stubborn cases. Each layer builds on the last, and finding the right combination for your skin is what ultimately makes the biggest difference.
