What skin condition is characterized by red, inflamed patches and flaky skin?

The skin condition characterized by red, inflamed patches and flaky skin is psoriasis. Psoriasis is a chronic autoimmune disorder that primarily affects the skin, causing the rapid buildup of skin cells, which leads to scaling on the skin's surface. The inflamed patches can vary in size, often associated with a silvery-white scale, and commonly occur on elbows, knees, scalp, and lower back. The inflammation and flakiness result from the underlying immune system overactivity, which triggers the accelerated growth of skin cells.

In contrast, dermatitis typically presents with redness and irritation but can vary in its manifestations, often related to contact with irritants or allergens. Acne is mainly associated with clogged pores resulting in pimples, blackheads, and cystic lesions rather than flaky patches. Rosacea affects the face and is marked by persistent redness and visible blood vessels, but it does not generally present with flaky patches as seen in psoriasis.
