Which skin condition is characterized by red, scaly patches?

The condition characterized by red, scaly patches is psoriasis. This skin disorder is an autoimmune disease that accelerates the growth cycle of skin cells, resulting in the rapid buildup of cells on the surface of the skin. The excess skin cells form thick, silvery scales and red patches that can be itchy and sometimes painful. Psoriasis can appear anywhere on the body, but it is commonly found on the elbows, knees, and scalp.

In contrast, acne involves clogged pores and is primarily associated with blemishes, blackheads, and whiteheads rather than scaly patches. Eczema, while it can also cause red patches, is typically associated with dry, itchy skin rather than the specific scaling seen in psoriasis. Dermatitis is a broader term that refers to inflammation of the skin and can present in various forms, but again does not specifically describe the red, scaly patches characteristic of psoriasis. Therefore, psoriasis is the most accurate answer to this question.
