Eczema inflammation starts when your immune system overreacts in the skin, producing signaling molecules that break down your skin’s protective barrier and trigger redness, swelling, and itch. Reducing that inflammation requires a combination of repairing the barrier, calming the immune response, and avoiding the triggers that restart the cycle. The right approach depends on how severe your flare is, but most people benefit from layering several strategies together.
Why Eczema Skin Stays Inflamed
In eczema, immune cells in the skin release inflammatory signals, particularly IL-4, IL-13, and IL-22. These three molecules each damage the skin barrier in overlapping but distinct ways. They reduce production of filaggrin, a protein that keeps your outer skin layer tightly sealed, and claudin-1, which helps skin cells stick together. The result is skin that loses moisture quickly and lets irritants, allergens, and bacteria slip through more easily.
That barrier breakdown creates a feedback loop. As the skin leaks more moisture and absorbs more irritants, immune cells ramp up even further. IL-4 and IL-13 also suppress your skin’s natural antimicrobial defenses, which is why eczema patches are so prone to bacterial colonization. Breaking this cycle at any point, whether by sealing the barrier, quieting the immune signals, or reducing bacterial load, helps bring inflammation down.
Moisturizers That Rebuild the Barrier
Daily moisturizing is the foundation of eczema management, but not all moisturizers work equally well. Ceramide-containing creams and ointments are particularly effective because ceramides are the same type of fat naturally found in healthy skin barriers. In studies of people with mild to moderate eczema, ceramide-based formulations reduced water loss through the skin, improved the structure of the outermost skin layer, and increased the lipid content that keeps skin sealed. Look for products that list ceramides (ceramide NP, AP, or EOP) near the top of the ingredient list.
Ointments trap more moisture than creams, and creams trap more than lotions. For the best results, apply your moisturizer within a few minutes of bathing while skin is still slightly damp. This locks water into the outer layer of skin. During a flare, you may need to reapply two or three times a day. Fragrance-free formulations are essential since added fragrance is one of the most common contact irritants for eczema-prone skin.
Topical Steroids for Active Flares
When moisturizing alone isn’t enough, topical corticosteroids are the most widely used treatment to bring a flare under control. They work by broadly suppressing the immune activity in the skin, reducing redness, swelling, and itch within days.
Steroids are classified into seven potency levels in the U.S., from class VII (least potent, like over-the-counter hydrocortisone 1% or 2.5%) up to class I (superpotent prescriptions like clobetasol propionate 0.05%). Your provider chooses the potency based on where the eczema is and how severe it is. Thin skin areas like the face, eyelids, and skin folds typically call for low-potency options (class VI or VII), while thicker skin on the hands, feet, and trunk can handle medium or high potency. The goal is to use the lowest effective strength for the shortest time needed to clear the flare, then step down to moisturizers or a non-steroidal option for maintenance.
A common approach is to apply the steroid once or twice daily until the flare resolves, usually within one to two weeks, then taper off. Some providers recommend “proactive” therapy: applying a low-potency steroid to previously flared areas two days a week to prevent the next flare from taking hold.
Non-Steroidal Prescription Options
For people who need ongoing treatment but want to avoid long-term steroid use, several non-steroidal topicals can keep inflammation in check. Crisaborole is a topical ointment that works by blocking an enzyme called PDE4. Normally PDE4 breaks down a molecule (cAMP) that acts as a natural brake on inflammation. By blocking PDE4, crisaborole lets that brake stay engaged, reducing the production of the same inflammatory signals (IL-4 and IL-13) that drive eczema flares.
A newer category targets the JAK-STAT pathway, which is the internal relay system that inflammatory signals use to activate immune cells. Delgocitinib 2% cream is the first FDA-approved topical JAK inhibitor, currently indicated for moderate to severe chronic hand eczema in adults who haven’t responded to topical steroids. It blocks multiple points in this relay system simultaneously, suppressing a broad range of inflammatory signals. Calcineurin inhibitors like tacrolimus and pimecrolimus are another steroid-free option, particularly useful for sensitive areas like the face and eyelids where long-term steroid use carries higher risks of skin thinning.
Biologics for Moderate to Severe Eczema
When topical treatments aren’t controlling inflammation adequately, injectable biologics can target the immune signals driving eczema at a systemic level. Dupilumab, the most established biologic for eczema, blocks the receptors for IL-4 and IL-13, the two key signals responsible for barrier breakdown and immune overactivation. In clinical trials, 42% of adolescents and a consistently higher proportion of adults achieved 75% skin clearance after 16 weeks, compared to just 8-15% on placebo. That’s a meaningful difference for people living with widespread disease.
Dupilumab is given as an injection under the skin every two weeks. Because it specifically targets the type-2 immune pathway rather than broadly suppressing the immune system, it carries a different risk profile than older systemic treatments. Other biologics and oral JAK inhibitors have since been approved, expanding options for people whose eczema doesn’t respond to dupilumab alone.
Phototherapy for Widespread Inflammation
Narrowband UVB phototherapy uses a specific wavelength of ultraviolet light to reduce immune cell activity in the skin. It’s typically offered two to three times a week for about 12 weeks, administered in a dermatologist’s office or specialized clinic. In studies of both adults and children with moderate to severe eczema, 40% of patients achieved clearance or near-clearance of their skin, with remission lasting a median of three months after a completed course.
Phototherapy works well for people with widespread eczema that would require large amounts of topical medication to cover. The main downsides are the time commitment of frequent office visits and the cumulative UV exposure over many sessions.
Bleach Baths to Reduce Bacterial Load
Eczema skin is frequently colonized by Staphylococcus aureus bacteria, which worsens inflammation and can trigger flares. Dilute bleach baths reduce this bacterial burden without antibiotics. The Mayo Clinic recommends adding 1/4 cup of regular household bleach to a 20-gallon tub of warm water (or 1/2 cup for a full tub), soaking from the neck down for 5 to 10 minutes, once or twice a week. The concentration is similar to a swimming pool.
Always apply moisturizer immediately after patting skin dry. Bleach baths aren’t a standalone treatment, but as an add-on to your regular routine, they can meaningfully reduce the frequency and intensity of flares driven by bacterial colonization.
Coconut Oil as a Natural Anti-Inflammatory
Virgin coconut oil has both moisturizing and antimicrobial properties that make it a useful supplemental treatment. In a study of adults with eczema, applying virgin coconut oil for several weeks reduced Staphylococcus aureus colonization dramatically: only 5% of coconut oil users still tested positive for the bacteria afterward, compared to 50% of those using olive oil. The lauric acid in coconut oil is responsible for much of this antibacterial effect.
Coconut oil works best as a moisturizer for mild eczema or as a complement to prescription treatments. It won’t replace topical steroids during a significant flare, but for day-to-day barrier maintenance and bacterial control, it’s an inexpensive option with a low risk of irritation.
Probiotics and Gut-Skin Connection
There’s growing evidence that the bacteria in your gut influence skin inflammation. A meta-analysis pooling data from 12 clinical studies found that probiotic supplementation produced a moderate to large reduction in eczema severity scores. The most commonly studied strains belong to the Lactobacillus family, including L. rhamnosus, L. paracasei, L. acidophilus, and L. fermentum. Bifidobacterium strains, particularly B. lactis and B. longum, have also shown benefit.
Most of this research has been conducted in children, so the strength of evidence is stronger for pediatric eczema than adult. Probiotics are unlikely to replace topical treatment, but they may help reduce flare frequency and overall severity as part of a broader management plan. If you try them, give it at least 8 to 12 weeks to see a meaningful difference.
Daily Habits That Lower Flare Risk
Beyond specific treatments, several everyday adjustments reduce the baseline level of inflammation in eczema-prone skin. Bathing in lukewarm rather than hot water prevents stripping the skin’s natural oils. Keeping baths or showers short, around 10 minutes, limits moisture loss. Wearing soft, breathable fabrics like cotton next to the skin reduces friction and irritation. Keeping indoor humidity between 40% and 60% helps prevent the skin from drying out, particularly in winter when heating systems pull moisture from the air.
Stress is a well-documented eczema trigger because stress hormones amplify the same immune pathways involved in flares. Regular sleep, physical activity, and stress management techniques won’t cure eczema, but they reduce the frequency of immune flare-ups. Identifying and avoiding your personal triggers, whether that’s certain fabrics, pet dander, dust mites, or specific foods, gives your skin barrier fewer insults to recover from between flares.
