Plaque psoriasis is the most common type of psoriasis and appears as raised, red patches covered with a silvery white buildup of dead skin cells or scale. These patches or plaques most often appear on the scalp, knees, elbows and lower back. They are often itchy and painful, and they can crack and bleed.1
Psoriasis affects approximately 1% to 3% of the Canadian population.2
The burden of plaque psoriasis extends beyond the physical symptoms; its impact on physical and mental function is similar to that of cancer, depression, and many other chronic diseases.3
