Eczema is a health condition affecting the skin. It is also called dermatitis. The main symptoms are dryness, redness and itchiness of the skin.
When the Eczema Mailing List was set up in the mid 1990s, there were few reliable online information resources about the condition. That has changed. So rather than provide an extensive overview here, we suggest that you make use of the resources of the National Eczema Society (UK) and the National Eczema Association (USA) as well as other reputable online medical sources.
Information gleaned online can be valuable in helping to understand and manage a health condition, but it isn't a substitute for a consultation with a qualified health professional. Always consult your doctor.
