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

Psoriasis is the skin disorder characterized by the overproduction of skin cells. This condition leads to the rapid build-up of skin cells on the surface, which can create thick, red patches covered with silvery scales. The process of skin cell turnover is accelerated in psoriasis, with cells moving from the basal layer to the surface in a matter of days instead of the usual weeks. This excessive proliferation of skin cells results in the distinctive appearance and discomfort associated with the condition. Psoriasis is often linked to immune system dysfunction and can also be influenced by genetic factors, making it a complex condition beyond simple skin cell accumulation.

In contrast, other skin disorders listed, such as acne, eczema, and dermatitis, involve different underlying mechanisms or reactions such as inflammation, blockages in hair follicles, or hypersensitivity, rather than a primary issue with skin cell production.
