Psoriasis is a condition that causes red and crusty patches of skin covered with silvery scales.

The main symptoms of psoriasis are patches of skin that are dry, red and covered in silver scales.

Mild psoriasis can be treated with creams and ointments. If these do not work, you may need light treatment (phototherapy) or stronger medicines.

Psoriasis is thought to be caused by a problem with the immune system, which causes your body to make too many skin cells.

Psoriasis typically causes patches of skin that are dry, red and covered in silver scales. Some people find their psoriasis causes itching or soreness.

There are several different types of psoriasis. Many people have only 1 form at a time, although 2 different types can occur together. One form may change into another or become more severe.

Most cases of psoriasis go through cycles, causing problems for a few weeks or months before easing or stopping.

You should see a GP if you think you may have psoriasis.

Medical treatments

There's no cure for psoriasis, but a range of treatments can improve symptoms and the appearance of skin patches.

In most cases, the first treatment used will be a topical treatment, such as vitamin D analogues or topical corticosteroids. Topical treatments are creams and ointments applied to the skin.

If these are not effective, or your condition is more severe, a treatment called phototherapy may be used. Phototherapy involves exposing your skin to certain types of ultraviolet light.

In severe cases, where the above treatments are ineffective, systemic treatments may be used. These are oral or injected medicines that work throughout the whole body.
