Psoriasis is a chronic autoimmune skin condition that causes the rapid buildup of skin cells. This buildup leads to scaling on the skin's surface, which can appear as red patches covered with thick, silvery scales. The condition is often itchy and can be painful. Psoriasis can occur on various parts of the body, including the elbows, knees, scalp, and lower back.
The exact cause of psoriasis is not fully understood, but it is believed to involve a combination of genetic, environmental, and immune system factors. While there is no cure for psoriasis, various treatments can help manage symptoms, including topical treatments, phototherapy, and systemic medications.
