Contact Dermatitis: Identifying and Avoiding Triggers

Contact dermatitis is an inflammatory skin condition that occurs when the skin comes into direct contact with a substance that either irritates it or triggers an allergic reaction. It is one of the most common skin conditions, accounting for a large proportion of work-related skin disease. The resulting rash is characterized by redness, itching, swelling, blistering, and sometimes crusting, confined to the area of contact with the offending substance. There are two main types of contact dermatitis. Irritant contact dermatitis is the more common form and occurs when a chemical or physical agent directly damages the skin barrier. It does not involve the immune system and can happen on first exposure to a sufficiently irritating substance. Common causes include harsh soaps and detergents, prolonged water exposure, solvents, acids, alkalis, and friction. Healthcare workers and food handlers who perform frequent hand washing are particularly susceptible. Allergic contact dermatitis involves an immune-mediated reaction that typically develops after previous sensitization to an allergen. On subsequent exposures, the immune system mounts a response causing the dermatitis. The reaction usually appears 24 to 48 hours after contact and can occur even with substances previously tolerated for years. Common allergens include nickel in jewelry, fragrances in cosmetics and personal care products, preservatives, rubber chemicals in gloves, poison ivy and other plants, and certain topical medications.

Identifying the causative substance is essential for management. A detailed history focusing on exposures at work, home, and during hobbies often provides important clues. Patch testing performed by a dermatologist or allergist applies standardized panels of common contact allergens to the back and is the gold standard for diagnosing allergic contact dermatitis. Treatment involves removing the offending substance when identified, applying topical corticosteroids to reduce inflammation, using emollients to restore the skin barrier, and avoiding scratching.
