Psoriasis is characterized by the development of patches of dry, flaky skin due to an accelerated skin cell turnover rate. In this condition, the skin cells multiply too quickly, leading to a buildup of cells on the surface of the skin, which forms thick, silvery scales. These patches can be itchy and uncomfortable, often appearing on the scalp, elbows, knees, and lower back.

Individuals with psoriasis may experience flare-ups that can be triggered by stress, weather changes, or certain medications. Unlike other skin conditions that may cause redness, inflammation, or irritation, psoriasis is specifically noted for the presence of these distinctive dry, flaky patches, making it a hallmark symptom of the condition.

Understanding this characteristic can help differentiate psoriasis from other skin conditions that may also cause skin irritation or dryness but are defined by different symptoms or underlying causes. For example, eczema is primarily associated with intense itching and can occur in various forms; rosacea presents with redness and visible blood vessels rather than dry patches; and allergic dermatitis often results from contact with allergens, leading to localized inflammation and redness.
