Psoriasis is characterized by an abnormally excessive and rapid growth of the epidermal layer of the skin. Abnormal production of skin cells (especially during wound repair) and an overabundance of skin cells result from the sequence of pathological events in psoriasis.
Doctors believe that psoriasis is caused by abnormalities in the immune system, enzymes, and other factors that regulate skin cell division. Part of the process involves an abnormal immune response, which causes inflammation and rapid production of immature skin cells.
