Nickel Allergy and Jewelry: Everything You Need to Know

Nickel allergy and jewelry: Everything you need to know. In short: A nickel contact allergy is a type IV hypersensitivity reaction of the immune system. The immune system recognizes nickel ions released from jewelry onto the skin as a foreign substance and triggers an inflammatory reaction. If symptoms persist, seeking medical advice is the right course of action. Reactions usually appear at clasps and soldered joints, not across the entire surface.

As of September 2026. By Phil, Corelune Jewellery, Düsseldorf.

Symptoms: Redness, itching, eczema, swelling, and rarely, blistering. The reaction typically appears 12 to 48 hours after initial contact and may occur more quickly upon repeated contact. Once developed, the allergy is long-lasting.

Redness, itching, and small blisters after wearing a new ring—that is a classic nickel contact allergy. It affects an estimated 15 to 20% of the population in Germany and is the most common contact allergy worldwide. Even for sensitive skin, there are suitable options. This comprehensive guide explains everything about nickel allergy and jewelry, from the causes to safe materials.

How much nickel can jewelry release?

In the EU, there is a clear rule: The EU nickel directive (EN 1811) limits the nickel release from jewelry to a maximum of 0.5 micrograms per square centimeter per week for items that come into direct contact with the skin (stud earrings, rings, bracelets). For piercings, the limit is even stricter: 0.2 micrograms/cm²/week. Products that meet these limits may be labeled "resistant according to EU directive." Important: "resistant" does not mean "nickel-free"; it means that the release is below the legal limit.

Materials ranked by safety

Absolutely safe (nickel-free)

• Titanium (G23): The only truly resistant metal that is also recommended for piercings. Completely biocompatible, lightweight, and resistant.
• 585 / 750 yellow gold: Gold alloys contain no nickel, but rather copper and silver. Very well tolerated.
• Platinum: resistant, resistant.
• Niobium: Rare metal used in jewelry.

Frequently chosen for sensitive skin

• Stainless steel at Corelune: nickel-free, waterproof, and tarnish-resistant. Biocompatible and approved for medical implants.
• 925 sterling silver: Silver itself is resistant, but the copper (7.5%) sometimes causes mild reactions—not a nickel reaction.

Not recommended

• Brass (copper-zinc alloy): Often contains nickel, especially in inexpensive fashion jewelry
• White gold without certification: Traditional white gold is alloyed with nickel; only buy if explicitly stated as palladium-alloyed or proven to have a low nickel content
• Unknown alloys: No stamp, no information—stay away

What to do if a reaction occurs?

1. Remove the jewelry immediately
2. Rinse the affected skin with clear water
3. A corticosteroid cream from the pharmacy (hydrocortisone 0.5%) relieves inflammation
4. Do not try the same piece again
5. If the reaction is severe or spreads, consult a dermatologist
6. An allergy test by a dermatologist, such as an epicutaneous test, can clearly confirm or rule out a nickel allergy

Practical tips for sensitive skin in everyday life

• Test new jewelry: Wear it for 1 to 2 hours first and monitor your skin before wearing it all day
• Nail polish on the inside of the ring: Clear nail polish acts as a temporary barrier for mild sensitivities
• Never swim with jewelry: Sweat and chlorine increase nickel release
• Buy quality: Inexpensive jewelry without material information poses the greatest risk

Nickel allergy and piercings

Fresh piercings are particularly vulnerable because the skin is damaged and the barrier function is impaired. Use exclusively G23 titanium for fresh piercings. No solid stainless steel, silver, or gold—only titanium is safe enough for fresh wounds. After complete healing (6 to 12 months), you can switch to other materials.

Frequently asked questions

How do I find my ring size?

Measuring at the end of the day provides a useful value. Wrap a strip of paper around your finger and note the circumference in millimeters—that is the German ring size.

Can a stainless steel ring be resized?

Stainless steel rings are difficult to resize because the material is hard to work with. Therefore, exchanging the ring within the return period is usually the quickest option.

Which rings are best for stacking?

Yes, two to three narrow rings on one finger work well, while keeping the rest of the hand simple. Anything else quickly becomes overwhelming.
