Psoriasis is a chronic autoimmune condition that causes rapid skin cell turnover, leading to thick, red patches covered with silvery-white scales. It often appears on the scalp, elbows, knees, and lower back, but it can develop anywhere on the body. Psoriasis is not contagious and can vary in severity, from mild localized patches to widespread flare-ups. While there is no permanent cure, proper management can significantly reduce symptoms and improve skin health.
