What skin condition is characterized by red, inflamed patches often covered with silvery scales?

Psoriasis is a chronic autoimmune condition that leads to the rapid growth of skin cells, resulting in the development of red, inflamed patches that are often covered with silvery-white scales. This characteristic appearance is due to the accumulation of skin cells that have not shed properly, creating the scaly texture associated with psoriasis.

The redness of the affected areas stems from inflammation, which is a hallmark of the condition. Unlike other skin conditions, psoriasis often appears in distinct plaques and can be quite noticeable due to the contrast between the red skin and the silvery scales. This condition can also be triggered by various factors, including stress, infections, and certain medications, making it unique among skin disorders.

In contrast, eczema typically involves itchy, inflamed skin often without the distinctive silvery scales. Rosacea usually presents with redness and visible blood vessels primarily on the face, often accompanied by bumps, but does not have the scaly appearance. Dermatitis can refer to a range of skin inflammations, including contact dermatitis, which may result in red, itchy patches but lacks the hallmark silvery scaling seen in psoriasis.
