Psoriasis is a chronic skin disease, which is characterized by thick red, flaking spots on the skin. This can cause pain and itch. The condition is caused by a defect in skin growth. There are periods of temporary deterioration and improvement. A person can also have nail defects and joint problems in case of psoriasis.


Normally, the skin is gradually renewed. Old skin cells are released at the outside and new skin cells grow at the underside of the epidermis. In case of psoriasis, the skin growth is accelerated and the surplus of cell layers is not disposed. This causes skin slices with a thick layer of immature skin cells that are difficult to flake off. The cause of this disturbed skin production is genetic in nature.
Symptoms can begin or worsen due to skin damage (cutting wound, abrasion), burning of the skin, stress or infections. Psoriasis can possibly slightly worsen when using certain medicines, for example lithium, beta blockers, malaria pills and certain painkillers, such as ibuprofen and diclofenac. The condition is more common in people who regularly smoke or drink alcohol. Psoriasis is not contagious.
