Common Causes and Sources of Skin Allergy

These are the most potent causes of skin allergy and their most likely sources. In some cases, not all items in each category contain the allergen. For example, not all jewelry contains nickel, and not all medications contains benzocaine. Check all items you use routinely to determine possible causes of skin reactions.
