For now, Fowler has this advice for eczema sufferers and others with skin issues: Start with good skin-care habits by avoiding harsh soaps and scratchy clothing and by using a good moisturizer. If you're experiencing a flare, topical steroids generally do the trick but can cause thinning of the skin if they're used too often. Nonsteroidal treatments such as Elidel and Eucrisa work, too, and are safer to use on the face than steriods. Low-tech methods such as diluted bleach baths may reduce bacterial growth on the skin while prescription medication such as methotrexate and Dupixent can mediate or suppress an overactive immune system, reining in an eczema flare.
