Psoriasis is a chronic skin disease. The disease manifests itself as red spots covered with white scales, which most often appear on the torso, elbows, knees and scalp, and as small spots on the skin or red skin that are most often under the armpits, female genitals, groin, hands, feet and nails.

In this disease, the cells multiply faster than they manage to produce keratin, which is responsible for the hard surface of the skin. The cause of psoriasis is not known, but all indications are that genes are responsible, in combination with genetic factors. There is a possibility that psoriasis can be triggered by infections and stress.

Psoriasis can occur at any age and in both sexes, but is most common in young people under the age of 25. Psoriasis is not contagious.
