Psoriasis is a chronic autoimmune skin condition that causes the rapid buildup of skin cells, leading to thick, red, scaly patches on the skin. These patches commonly appear on the scalp, elbows, knees, lower back, and hands, and may cause itching, burning, dryness, or discomfort. Psoriasis is not contagious and can affect people of all ages. The condition may be triggered by stress, infections, certain medications, weather changes, or genetic factors. Although there is no permanent cure, psoriasis can be effectively managed with proper treatment, lifestyle modifications, medicated creams, phototherapy, and advanced dermatological care to reduce symptoms and improve quality of life.
