Psoriasis is a non-contagious skin disease that affects almost 10 million people across North America. About 500,000 people are living with psoriasis in Canada. Psoriasis usually appears between the ages of 15 and 35 and the average age at diagnosis is 28, but people of any age can be affected.
In the most common form of psoriasis, plaque psoriasis, certain areas of the skin develop red patches of various sizes, covered with dry, silvery scales. The skin lesions can be painful and itchy. Inflammation will come and go for people with psoriasis, and presently there is no known cure.
