Psoriasis is a chronic autoimmune skin condition characterized by the rapid growth of skin cells, leading to thick, red, scaly patches on the skin's surface. These patches can be itchy and painful and often appear on areas such as the elbows, knees, and scalp. The exact cause of psoriasis is not fully understood, but it involves an overactive immune response and genetic factors. Treatment options include topical therapies, phototherapy, and systemic medications to help manage symptoms and reduce flare-ups.
