Key Symptoms: Redness and inflammation of the skin Itching and burning sensation Swelling of the affected area Blistering or oozing in severe cases Dryness, cracking, or peeling of the skin Localized rash often appearing where contact occurred Delayed skin reaction, typically developing hours to days after contact

Diagnosis Path: Diagnosis of allergic contact dermatitis usually involves a detailed medical history and physical examination. The healthcare provider may ask about recent exposures to new products, jewelry, or plants. Patch testing is a common diagnostic tool, where small amounts of potential allergens are applied to the skin under controlled conditions to observe reactions. This helps identify specific substances causing the allergy. No additional laboratory tests are typically necessary unless other skin conditions are suspected.

Treatment Protocols: Treatment focuses on relieving symptoms and removing exposure to the allergen. Common approaches include: - Avoiding known or suspected allergens - Using topical corticosteroids to reduce inflammation - Applying moisturizers to soothe irritated skin - Taking antihistamines to manage itching - Protecting skin from further contact by wearing protective clothing or barriers Severe cases may require medical consultation for additional interventions, such as prescription medications or specialized skin care. It's important to identify and avoid contact with the identified allergen to prevent recurrence.
