What causes psoriasis?

The cause of psoriasis is not fully known, but it is thought to relate to an overactive immune system. Although there is no apparent reason, certain immune pathways in the skin begin to act as if there is an infection or a wound, causing the skin cells to multiply very quickly. This leads to the development of the red and scaly plaques on the skin surface. Both genes and the environment play a part in the development of psoriasis. If you have psoriasis you may find that certain substances or activities – triggers – can make it worse. Common triggers may include stress, infections, smoking, alcohol, cold weather and some medicines.
