NICKEL (the metal): Allergen or Not An Allergen?

Allergen.

Not just an allergen or a top allergen…nickel is frequently the number one most common allergen on published allergen lists, and was the 2008 Allergen of the Year of the American Contact Dermatitis Society.

Watch for it in coins; chromed faucets, handles or armrests; certain eyeglass frames or parts, mobile phones or their cases, laptops and other electronics, cosmetic containers, fabrics (invisible as chemicals added to help dyes bind better), and even some makeup shades.

It is very rare for metals not to have some nickel in them. If you are allergic, look for very high-quality metals such as high-end stainless steel — because the nickel tends to be bonded extremely well, the chances of it rubbing off and causing a reaction are minimized.

If you think you might have contact dermatitis, ask your dermatologist for a patch test.

Regularly published reports on the most common allergens by the North American Contact Dermatitis Group and European Surveillance System on Contact Allergies (based on over 28,000 patch test results, combined), plus other studies. Remember, we are all individuals — just because an ingredient is not on the most common allergen lists does not mean you cannot be sensitive to it, or that it will not become an allergen. These references, being based on so many patch test results, are a good basis but it is always best to get a patch test yourself.

[…] Nickel has been the number one contact allergen for years, was the 2008 Allergen of the Year of the American Contact Dermatitis Society, and is everywhere. When we say that a stainless steel water bottle is probably not a contact allergen, we assume that it is a pretty plain, straightforward bottle (no chrome or nickel finish) and of very high-quality stainless steel. In very high-quality metals, the nickel is bonded very well. This significantly reduces the chances of the nickel being rubbed off. This is important because nickel is dissolved by sweat (a “microbial corrosion”), resulting in its absorption and penetration into the skin, which is what causes the allergic reaction. […]
