What is a key characteristic of psoriasis?

Psoriasis is primarily recognized as a chronic autoimmune condition that causes the rapid buildup of skin cells, resulting in red, dry lesions that are typically covered by silvery scales. This characteristic buildup is a hallmark of psoriasis, leading to the formation of thick patches on the skin, which can be itchy and painful. The nature of psoriasis is chronic, meaning it persists over time, with varying degrees of severity and periodic flares. Its classification as an autoimmune disorder also differentiates it from infections, which involve bacteria or fungi. Understanding this key characteristic is essential for accurate diagnosis and effective management of the condition.
