Metals such as nickel, chrome and mercury are also common causes of skin allergies. Jewelry, snaps and zippers on clothing may contain these elements. A number of cosmetics contain dyes and perfumes that can cause allergic reactions in some people. In such cases, hypo-allergenic products are often the solution. Drugs such as penicillin and some local anesthetics can also cause reactions.
Many times doctors can prescribe an alternative treatment for people with drug allergies.
In all skin allergy cases, avoiding the irritant is the best treatment but if contact does occur and the area becomes infected, see your doctor. This information is not a tool for self-diagnosis or a substitute for professional care.
