Open all pages about Psoriasis
Psoriasis is thought to be caused by a problem with the immune system, which causes your body to make too many skin cells.
Mild psoriasis can be treated with creams and ointments. If these do not work, you may need light treatment (phototherapy) or stronger medicines.
The main symptoms of psoriasis are patches of dry skin that are covered in silvery-white or grey scales.
