Psoriasis is the most frequent and severe dermatosis. It is a chronic and autoimmune disease, in the course of which the immune system stimulates skin cells to develop quicker and overlap over the old ones. It leads to cell accretion on the skin’s surface. Skin cells become thick and ascend over the surface, forming silver furfurs, which itch and desquamate.

Sunlight is available for psoriasis patients most of the time, but in some cases it is also recommended to consider ultraviolet light therapy for psoriasis.
According to results from research, UVB rays with the wave length of 311 nm clear skin from patches much faster and provide remission for a longer term.
Phototherapy, in the course of which UV lamp with narrow band B rays is used, is distinguished by many advantages. The main ones are:
Besides ultraviolet irradiation is an effective method.
