Psoriasis is a chronic autoimmune condition that causes the rapid buildup of skin cells, resulting in thick, scaly patches on the skin. These patches, often called plaques, are typically red or pink with silvery scales and may appear on the scalp, elbows, knees, lower back, or other areas. Psoriasis can cause itching, burning, or discomfort, and the severity can vary from mild to severe. The condition is triggered by the immune system mistakenly attacking healthy skin cells, speeding up the production of new skin cells. Factors such as stress, infections, certain medications, or skin injuries can trigger flare-ups. While there is no cure, psoriasis can be managed with treatments such as topical creams, light therapy, and medications that reduce inflammation and slow down skin cell growth. Managing lifestyle factors like stress and maintaining a healthy skin care routine can also help control symptoms.
