Allergy to nickel is a phenomenon which has assumed growing importance in recent years, largely because of the introduction of cheap fancy jewellery in which the underlying metal layer consists of nickel. 10 to 12% of the female population and 6% of the male population are estimated to be allergic to nickel. In fact the allergy is not caused by nickel itself but by the nickel salts which are formed under the effect of perspiration in contact with the piece of jewellery piece or watch. This phenomenon is always accompanied by corrosion of the object.(reference)
Nickel allergy on the lobe due to contact with nickel
degree of allergy varies. Some people develop dermatitis (also called eczema) from even brief contact with nickel-containing items, while others break out only after many years of skin contact with nickel. Some people develop intermittent or persistent eczema on their hands and feet. It is usually a blistering type of eczema, known as pompholyx. Sometimes it is due to contact with metal items containing nickel, but often there is no obvious reason for it. It has been suggested that in some, dyshidrotic hand dermatitis is due to nickel in the diet. Unfortunately it is not possible to avoid ingesting nickel as it is present in most foodstuffs. A low-nickel diet is only rarely helpful.
If you suffer from this type of allergy you should avoid contact with nickel-containing metals. Test your metal items to see if they contain nickel. Obtain a nickel-testing kit from your dermatologist or pharmacist. The kit consists of two small bottles of clear fluid. One contains dimethylglyoxime and the other ammonium hydroxide. When mixed together in the presence of nickel, a pink color results. Apply a drop from each bottle on to the metal item to be tested, first try it on a 10 cent coin. Use a cotton bud to rub gently - observe the color on the bud. If it remains clear, the item has no free nickel and will not cause dermatitis. If it is pink it contains nickel and may cause problems if the metal touches your skin. The chemicals will not harm your jewelry.
