Cause: Contact dermatitis is typically caused by direct skin contact with irritants or allergens. Common irritants include soaps, detergents, solvents, and harsh chemicals. Allergens can include poison ivy, poison oak, nickel, and certain cosmetic ingredients.
Symptoms: Symptoms include redness, itching, and a rash at the site of contact. In allergic contact dermatitis, the reaction may be delayed, appearing 24 to 48 hours after exposure.
Treatments: The primary treatment for contact dermatitis involves identifying and avoiding the irritant or allergen. Topical corticosteroids can help reduce inflammation and itching. For severe cases, systemic corticosteroids may be prescribed.
Prevention: Preventing contact dermatitis involves identifying and avoiding the specific irritant or allergen, often through patch testing by a dermatologist. Wearing protective clothing or gloves when handling irritants can also prevent contact dermatitis.
