Psoriasis is a non-contagious skin disease that affects almost 10 million people across North America. About 1 million people are living with psoriasis in Canada. The likelihood of developing psoriasis seems to peak between the ages of 30 and 39 years, and between 50 and 69 years old, but people of any age can be affected.
In the most common form of psoriasis, chronic 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.
