Mildly infected eczema can often be managed at home with bleach baths, proper moisturizing, and careful wound care, but knowing the difference between a minor bacterial flare and a spreading infection is critical. Some infections need prescription antibiotics, and no amount of home care will replace them. Here’s how to handle what you can at home and recognize when you can’t.
How to Tell if Your Eczema Is Infected
Eczema on its own causes itchy, inflamed skin that can ooze clear fluid and form crusts. Infection adds a different layer. The signs to watch for include yellowish-orange or honey-colored crusting on top of existing eczema patches, pus-filled blisters, sores that resemble cold sores or fever blisters, and reddish swollen bumps. You might also notice the skin feels warmer than usual around the affected area, or that the itch has shifted into something more painful.
The trickiest part is that eczema flares and infections share some symptoms, particularly swelling, oozing, and crusting. The distinguishing clues are color and pain. Clear or light-colored oozing is typical of a flare. Yellow, green, or honey-colored discharge, especially with increasing pain or warmth, points toward infection. If you see red streaks spreading outward from the patch, that’s a sign the infection is moving deeper and you need medical attention quickly.
Bleach Baths: The Most Effective Home Treatment
Dilute bleach baths are the single most recommended home strategy for infected eczema. They reduce the bacterial load on your skin without the resistance risks that come with antibiotic creams. Current dermatology guidelines actually recommend against routine use of topical antimicrobials for eczema, favoring bleach baths instead.
The ratio matters. For a standard U.S. bathtub filled to the overflow drain, add 1/4 cup of regular household bleach to about 20 gallons of warm water, or 1/2 cup for a completely full tub. Most U.S. bleach products contain 6% to 8.25% sodium hypochlorite. If yours is on the higher end of that range, use a little less. The resulting concentration is roughly equivalent to a swimming pool.
Soak from the neck down (or just the affected areas) for 5 to 10 minutes, once or twice a week. Don’t submerge your face. When you get out, pat your skin mostly dry, leaving it slightly damp, then immediately apply your moisturizer or any prescribed topical medication. That damp-skin window is when creams absorb best. During active flares with signs of infection, you can use bleach baths daily until things settle down.
Moisturizing and Skin Barrier Repair
Infected eczema means your skin barrier is already compromised, and bacteria thrive in cracked, dry skin. Generous, frequent moisturizing is not optional. Use a fragrance-free, thick cream or ointment rather than a lotion. Lotions have a higher water content and evaporate faster, which can actually dry you out more. Apply moisturizer at least twice daily and always within a few minutes of bathing.
Avoid anything with fragrance, dyes, or soap. Switch to a soap-free skin cleanser for washing. Regular soap strips the oils your skin desperately needs to heal and can worsen both the eczema and the infection.
Wet Wrap Therapy for Severe Flares
If your infected eczema is widespread or not responding to basic moisturizing, wet wrap therapy can help lock medication and moisture against the skin for extended periods. It’s more intensive but effective for stubborn patches.
Start with a lukewarm bath for about 15 minutes. Pat the skin mostly dry, then apply any prescribed topical medication followed by a generous layer of unscented moisturizer. Next, wrap the treated areas in damp (not dripping) gauze, fabric, or clothing that’s been soaked in warm water. For large areas, damp pajamas work well. Cover the wet layer with dry clothing or blankets to stay warm. Wear the wraps for about two hours, or overnight if the flare is severe.
This approach works well when combined with bleach baths. In severe cases where infection is present, some clinicians recommend adding a small amount of bleach to the soaking bath before applying wraps.
What About Topical Steroids?
If you already have a prescribed steroid cream, you might hesitate to use it on infected skin. Steroids can theoretically suppress local immune defenses and mask infections. But here’s the nuance: topical steroids remain the first-line treatment even for infected eczema, because controlling the inflammation is essential to letting the skin heal.
The key is that infection may need additional treatment on top of the steroid, not instead of it. If your doctor has given you a combination steroid-antibiotic cream, use it sparingly and for short periods, typically no more than about a week on a small area, to limit the risk of antibiotic resistance. Don’t use leftover antibiotic creams from old prescriptions to self-treat.
Over-the-Counter Antiseptic Washes
Beyond bleach baths, antiseptic skin cleansers can help reduce bacteria on eczema-prone skin. Chlorhexidine-based skin washes are available without a prescription and are commonly used for this purpose. Use them in place of soap during flares, not in addition to soap. The goal is to lower the bacterial count without further irritating already damaged skin.
These washes are a complement to bleach baths, not a replacement. They’re particularly useful for smaller areas or spots where a full bath isn’t practical, like patches on your hands or a single elbow.
Red Flags That Mean Home Care Isn’t Enough
Home treatment is reasonable for mild bacterial colonization: a little extra crusting, some localized warmth, slightly more oozing than usual. But certain signs mean the infection has progressed beyond what bleach baths and moisturizer can handle.
- Fever of any kind. This suggests the infection may be systemic. Seek emergency care.
- A rash that’s spreading rapidly or changing over hours rather than days. This also warrants emergency evaluation.
- Red streaks extending outward from the eczema patch, which can signal cellulitis, a deeper skin infection that requires oral or IV antibiotics.
- A growing, swollen rash without fever. See a healthcare provider within 24 hours.
- Pus-filled blisters that keep multiplying or sores that look like cold sores, which could indicate a viral infection (eczema herpeticum) that needs antiviral medication, not antibiotics.
Infected eczema that doesn’t improve within a few days of consistent home care also deserves professional evaluation. Bacterial infections sometimes need oral antibiotics, and viral or fungal infections require entirely different treatments that no amount of bleach baths will address.
