What skin condition is characterized by red patches covered with white-silver scales?

Psoriasis is a chronic skin condition that is clearly defined by its distinctive appearance of red patches that are often covered with thick, white-silver scales. This condition results from an accelerated skin cell life cycle, leading to an excessive buildup on the surface of the skin, causing the telltale plaques. The areas affected may be itchy, painful, and can vary in severity from minor to significant.

In contrast, eczema typically involves red, inflamed patches of skin that may ooze and crust over, rather than the scaly nature associated with psoriasis. Rosacea is characterized by facial redness and sometimes acne-like bumps, but does not present with the scaly patches that are hallmarks of psoriasis. Dermatitis is a broader term that can encompass several skin inflammation conditions but lacks the specific scaling that aids in identifying psoriasis. Understanding these distinctions can help in recognizing skins conditions accurately for treatment and management.
