Which skin condition is characterized by dry, flaky patches?

The skin condition characterized by dry, flaky patches is psoriasis. This chronic autoimmune condition leads to the rapid growth of skin cells, which form scales and dry patches on the skin surface, often causing irritation and discomfort. Psoriasis can appear anywhere on the body and is distinct for its thick, red patches covered with silvery scales that are sometimes itchy.

While eczema also involves dry, flaky skin, it typically presents as red, inflamed areas and can cause intense itching, showing more variability in its appearance compared to psoriasis. Acne, on the other hand, is primarily characterized by clogged hair follicles leading to pimples, blackheads, and cysts, rather than dry patches. Rosacea is a chronic condition primarily affecting the face and is marked by redness, visible blood vessels, and sometimes pimples, but it does not generally present with dry, flaky patches like psoriasis does. Therefore, psoriasis is the most fitting answer for dry, flaky patches.
