Can you suggest any remedies or treatment for eczema (atopic dermatitis) that you know to be effective?

Ceramide creams. The molecular defect in eczema skin is in the proper generation of barriers. Ceramides are found to be deficient in eczema skin. In addition to topical steroids, i generally recommend applying a ceramide containing cream (cerave or cetaphil restoraderm) first, and then 'seal' it on top with a more moisturizing lotion such as eucerin original lotion, or aquaphor if you are very dry.
