An itchy, swollen rash caused by direct contact with a substance or an allergic reaction to the substance.
What is it?
There are two primary types of contact dermatitis. The first is irritant dermatitis, which occurs when the skin reacts to harsh substances such as soaps, detergents and cleaning agents. Using gentle cleansers can help prevent irritant dermatitis.
The second type is allergic contact dermatitis, which happens when the skin encounters allergens, leading to an allergic reaction. Allergens can include adhesives, topical antibiotics, dyes from clothing or hair products, nail polish and certain plants like poison ivy or sumac. Identifying the exact cause of allergic contact dermatitis can be difficult due to the delayed onset of symptoms.
Although anyone can develop contact dermatitis, individuals with pre-existing skin conditions like eczema are at higher risk. Symptoms vary depending on the type and cause of dermatitis and often improve once the allergen or irritant is removed. However, persistent rashes may require professional evaluation by our team of board-certified dermatologists to determine the underlying cause and establish an appropriate treatment plan.
How is it treated?
Identifying the cause of skin irritation or swelling is crucial for effective management. To reduce swelling and discomfort, try applying a cool, damp cloth to the affected area. If the rash continues, don't hesitate to schedule an appointment our office. The team at Chapel Hill Dermatology provides various in-office treatment options, including topical corticosteroid creams or, in severe cases, oral corticosteroid medications, to address your specific needs.
