What skin condition is characterized by the overproduction of skin cells?

The skin condition characterized by the overproduction of skin cells is psoriasis. This chronic autoimmune condition causes the rapid growth of skin cells, leading to the formation of thick, red, scaly patches on the skin's surface. This excessive cell turnover means that skin cells do not shed in a typical manner, resulting in the buildup that is often itchy or painful. Psoriasis can appear in various forms, and it often manifests on the elbows, knees, scalp, and lower back, although it can affect any area of the body.

In contrast, rosacea is a chronic condition that causes facial redness and visible blood vessels, primarily involving inflammation rather than an overproduction of skin cells. Pemphigus is an autoimmune disorder that leads to blistering of the skin and mucous membranes, not a condition defined by cell overproduction. Asteatosis refers to dry skin caused by a lack of oil or moisture, which is unrelated to cell proliferation. Recognizing these distinctions is key to understanding skin conditions and their underlying mechanisms.
