Delayed immune reaction in a sensitised person after sufficient nickel exposure.

Nickel allergy
Allergic contact dermatitis caused by skin exposure to nickel released from a material, relevant to some jewellery, fasteners, coatings, chains and metal products.
Products & materials
In brief
Nickel content and nickel release are related but not identical product questions.
Nickel may be present in an alloy without being released at the same rate under every condition. Sweat, friction, prolonged contact, worn plating and surface damage can increase exposure. Nickel allergy usually causes delayed local dermatitis rather than immediate anaphylaxis, but broken or mucosal skin and persistent symptoms warrant clinical attention.
Non-allergic inflammation from friction, moisture, cleaning residue or another substance.
Metal whose composition includes nickel; release depends on formulation and surface condition.
Base material covered by a surface layer that may wear, crack or expose different metal.
Symptoms and diagnosis
Allergic contact dermatitis commonly causes itching, redness, scaling, dryness or small blisters at or near contact, often developing after repeated or prolonged exposure.
Appearance does not confirm nickel as the cause. A clinician or dermatologist can distinguish allergy from infection, friction injury and other dermatitis and may use patch testing.
Product evidence
Ask for accurate alloy and coating information and, where relevant, nickel-release compliance evidence. Terms such as surgical steel, stainless or hypoallergenic are not a complete specification.
A home spot test may indicate accessible nickel under its test conditions but cannot certify the whole object, future wear or every contact environment.
Exposure management
Avoid known triggers and stop using an item when symptoms occur. Keep surfaces dry and intact, inspect plating and do not rely on temporary clear coatings where wear is likely or contact is intimate.
Use an alternative material whose composition and finish are traceable. Another metal can still cause allergy or mechanical harm, so substitution is not universal certification.
Clinical and regulatory context
UK chemical restrictions can limit nickel release from specified articles, but compliance with one restriction does not prove suitability for every intimate or prolonged use.
Seek care for severe, spreading, infected-looking or persistent dermatitis. Tell clinicians about product composition, contact duration and cleaners used.
Non-graphic examples
What the umbrella may include
- Stopping use after an itchy rash under a metal fastener.
- Checking alloy and plating rather than relying on colour.
- Inspecting a coating for wear before contact.
- Choosing a traceable alternative after clinical diagnosis.
- Retaining product details for patch-test discussion.
