Psoriasis is a common skin disorder induced by erroneous signals sent by the auto-immune system, leading to extra fast skin cell renewal. The cells that regenerate with this faster pace cause other tissue to accumulate on the skin surface, generating a scale-like structure.

One to three percent of most populations have psoriasis, which is most prevalent in European countries. Psoriasis is an unpredictable condition that can sometimes flare up for no apparent reason. The course of the disease can be different in every individual who has it.
