Nickel allergy - Symptoms and causes

Did you know that nickel allergy is a common cause of allergic contact dermatitis — an itchy rash that appears where your skin touches a usually harmless substance.

Nickel allergy is often associated with earrings and other jewellery but it can also be found in many everyday items such as coins, zips, mobile phones and spectacle frames.

Skin absorption of nickel ions, released from nickel containing materials, can lead to sensitisation. The degree of sensitivity to nickel varies between individuals. This widespread health problem has forced the introduction of measures to reduce the development of allergic contact dermatitis to nickel.
