If your earlobes itch every time you wear a certain pair of earrings, if your piercings stay red and irritated for weeks longer than they should, or if cheap jewellery leaves your skin discoloured — you are very likely sensitive to nickel. You are not alone, and the fix is straightforward once you know what to look for.
Nickel allergy affects roughly 12–17% of women and 5% of men in Europe and is the most common contact allergy in adults. Symptoms in piercings include redness, itching, swelling, prolonged discharge and slow healing. The solution is to wear only nickel-free materials such as implant-grade titanium ASTM F-136, niobium, or solid 14k+ gold.
How Common is Nickel Allergy?
The European Centre for Allergy Research Foundation classifies nickel as the most prevalent contact allergen in the EU. Patch test studies across Germany, the UK, Portugal, France and Italy show:
• Around 17% of women aged 18–65
• Around 5% of men aged 18–65
• Higher prevalence in people pierced before the EU Nickel Directive was enforced
The EU Nickel Directive (REACH Regulation, Annex XVII, Entry 27) limits nickel release from jewellery sold in the EU to 0.5 µg/cm²/week for healed piercings and 0.2 µg/cm²/week for piercing post assemblies.
How to Recognise a Nickel Reaction
• Redness and inflammation around the piercing site
• Persistent itching, sometimes intense
• Clear or yellow discharge that does not resolve
• Skin that becomes thickened, scaly or weepy (eczema-like)
• In long-term cases, dark grey or black skin discolouration
| Material | Safe for nickel allergy? | Notes |
|---|---|---|
| Implant-grade Titanium F-136 | Yes | Gold standard for fresh and healing piercings |
| Niobium (pure) | Yes | Excellent biocompatibility |
| Solid 14k+ nickel-free gold | Yes (verify alloy) | Confirm white gold is palladium-based |
| Bioplast / PTFE | Yes | Metal-free option |
| Surgical steel 316L | No | Contains 10–14% nickel |
| Sterling silver | No | Tarnishes, may contain nickel |
| Gold-plated | No | Plating wears off |
Implant-Grade Titanium ASTM F-136 or F-1295
Effectively nickel-free. The gold standard for fresh and healing piercings.

Niobium
Pure niobium contains no nickel and is biocompatible.

Solid 14k+ Nickel-Free Gold
Genuine 14-karat or higher gold sourced as nickel-free is APP-approved for healed piercings. Some white gold contains nickel as a whitening agent — always confirm.
Bioplast / PTFE
Medical-grade flexible polymer. Free of all metals.
What to Avoid
• Costume jewellery and fashion-store earrings — usually nickel-rich plated brass.
• Standard 316L surgical steel — contains 10–14% nickel.
• Sterling silver in piercings — tarnishes in body fluids.
• White gold of unknown origin — may contain nickel.
• Gold-plated or vermeil pieces — the plating wears off.

How to Test Jewellery for Nickel
Pharmacies across Europe sell nickel spot tests (often branded Athena or DMG test kits). The test uses dimethylglyoxime, which turns pink in the presence of free nickel ions.
Living with Nickel Allergy
• Buy from sellers who specify the material standard (ASTM F-136, etc.)
• Avoid plating; choose solid materials
• Replace any jewellery older than 3–4 years if it is plated or unmarked
• Keep a small nickel test kit in your bathroom for new pieces
Frequently Asked Questions
Can a nickel allergy develop suddenly?
Yes. Nickel sensitisation builds up over time with repeated exposure. Many people develop visible reactions years after they first started wearing nickel-containing jewellery.
Are gold piercings nickel-free?
Solid yellow gold of 14k or higher from a reputable source is generally nickel-free. White gold often contains nickel as a whitening agent — always confirm.
Is sterling silver safe for nickel allergy?
Sterling silver is 92.5% silver and 7.5% other metals — usually copper, but sometimes nickel. It also tarnishes in body fluids. Not recommended for fresh piercings.
Can I get tested for nickel allergy?
Yes. A dermatologist can perform a patch test that confirms the diagnosis. In Portugal and most EU countries this is available through public and private dermatology clinics.
