Urticaria, commonly known as hives, and allergic skin reactions are hypersensitivity conditions characterized by the sudden appearance of itchy, raised wheals, redness, or swelling of the skin. These reactions may be acute or chronic and can vary in severity, duration, and frequency. Allergic skin conditions significantly affect comfort, sleep quality, and daily functioning and often require structured dermatological evaluation.

Acute urticaria typically develops suddenly and resolves within hours to days, often triggered by food exposure, infections, environmental allergens, insect bites, or physical stimuli. Chronic urticaria persists for weeks or months and may occur without an identifiable trigger, requiring detailed assessment and long-term management.

Allergic skin reactions may also present as contact dermatitis, where the skin reacts to irritants or allergens such as cosmetics, metals, chemicals, or fabrics. Symptoms may include redness, itching, swelling, blistering, or scaling at the site of contact. Repeated exposure can lead to chronic skin changes and increased sensitivity.

Dermatological assessment focuses on identifying potential triggers, pattern of recurrence, duration of symptoms, and associated systemic features. Differentiating between allergic, physical, and idiopathic causes is essential for effective management and prevention of recurrence.

Management emphasizes trigger avoidance, skin barrier protection, and reduction of inflammatory response. Patient education plays a key role in recognizing early signs, avoiding known triggers, and maintaining skin health.

Chronic urticaria and recurrent allergic skin reactions require ongoing dermatological follow-up to monitor symptom patterns and response to care. With structured management, most patients experience improved symptom control and quality of life.
