What is Allergic Contact Dermatitis?
Allergic contact dermatitis is a skin condition caused by a reaction to a contact allergen. The reaction does not occur upon first contact but after a second or repeated exposure over time to the same allergen. Common contact allergens include ingredients in fragrance and cosmetics; preservatives; rubber; plants; nickel, gold, and other metals; and many others. Allergic contact dermatitis can take many forms: a red, itchy rash; dry and cracked or scaly skin; bumps, blisters and lesions; and swelling and tenderness. Once you have developed allergic contact dermatitis, it is likely to recur. A personal or family history of other allergies may increase your chance of developing this skin condition.
