Eczema is a general name for a great number of different skin diseases with
symptoms like itching, reddishness, peeling, pimples, bladders etc. There are many
possible causes for eczema like allergy, irritation, dehydration, degreasing and fluid
accumulation under the skin. Radiation with UV-B or with UV-A in combination with
psoralen had proven to be effective for the curing of some types of eczema.
Furthermore ultraviolet radiation suppressed the immune system and reduced the
inflammatory responses as often seen by skin diseases like psoriasis and eczema.
There were also types of eczema however, that did not react or even deteriorate
when exposed to ultraviolet radiation. Treatment of eczema therefore always required
the supervision of a physician.
