Causes of Psoriasis

Psoriasis occurs as a protective reaction of the body. With the disease, the upper layers of individual areas of the skin die off faster. The normal cycle of maturation of skin cells lasts an average of 3-4 weeks, while with psoriasis, this time is reduced to 4-5 days. In medicine, psoriasis is considered a hereditary disease.
