Plaque Psoriasis

Plaque psoriasis is a chronic autoimmune skin condition in which the immune system mistakenly speeds up the life cycle of skin cells, causing them to build up rapidly on the surface of the skin. This buildup forms raised, red patches covered with thick, silvery-white scales, most commonly appearing on the elbows, knees, scalp, and lower back. The plaques can be itchy, painful, and sometimes crack or bleed. Plaque psoriasis is the most common type of psoriasis, and while it is not contagious, it tends to flare up in cycles triggered by factors such as stress, infections, cold weather, or certain medications.
