What do you need to know about nickel allergy?
Nickel allergic contact dermatitis (NACD) is a rash or eczema on the skin of people who are nickel-allergic. NACD is not a life threatening allergy and symptoms can be managed by limiting contact with items that release a lot of nickel.
Nickel allergy is not inherited but acquired by some people who are in direct and prolonged skin contact with items releasing high levels of nickel. Once a person is allergic to nickel, it takes less nickel release to the skin to cause NACD than the amount initially needed to make the person nickel-allergic.
