What characterizes psoriasis?

Psoriasis is primarily characterized by a chronic skin condition that manifests as red lesions that are covered with silvery scales. This condition is a result of an accelerated skin cell life cycle, leading to an overproduction of skin cells that accumulate on the surface. The distinctive appearance of psoriasis, with its raised, red patches and silvery scales, is a key identifying feature. These lesions often appear on various parts of the body, including the elbows, knees, and scalp, and can vary in severity from small patches to extensive areas.

The other characteristics listed do not align with psoriasis. Itchy red bumps and acne-like breakouts suggest different skin conditions, such as hives or acne, while dry patches with no discoloration could indicate skin conditions unrelated to psoriasis, such as eczema or simple dryness. Recognition of these distinct features is important for accurate diagnosis and treatment of skin conditions.
