ARVENIER
If jewellery makes your skin itchy, red or blistered where it touches, the most likely cause is a nickel allergy, the most common contact allergy. Metals that are usually better tolerated include titanium, niobium, 316L surgical stainless steel and nickel-free sterling silver. Keeping jewellery dry, removing it when sweating, and adding a barrier such as clear nail varnish can also help. A green mark on the skin is usually a harmless reaction with copper, not an allergy.
Is it an allergy or just discolouration?
- Itchy, red, bumpy or blistered skin that appears a day or two after wearing: likely an allergy, often to nickel.
- A green or black mark that washes off with no itch: usually copper or silver reacting with sweat. Not an allergy.
- Irritation only under rings: often trapped soap and water rather than the metal itself.
Why nickel causes problems
Nickel is common in alloys and in the base metal under plating because it is cheap, strong and bright. Sweat slowly releases nickel from the surface, and in sensitive people this triggers allergic contact dermatitis. Once someone is sensitised, the allergy usually lasts for life. The European Union limits how much nickel jewellery may release for exactly this reason.
Metals that are usually better tolerated
Plated alloy is the riskiest choice for sensitive skin, because once plating wears away the base metal touches the skin directly.
- Titanium and niobium: very low reactivity; often used for sensitive piercings.
- 316L surgical stainless steel: contains nickel bound tightly in the alloy, so release is low and most people tolerate it well, though not everyone.
- 925 sterling silver: usually silver and copper; well tolerated unless an alloy with nickel is used.
- High-karat gold (18k and above): low reactivity, but expensive.
How to wear fashion jewellery with sensitive skin
- Wear pieces for short periods, such as an evening out, rather than all day.
- Keep jewellery and skin dry; remove pieces before exercise, bathing and sleeping.
- Paint a thin layer of clear nail varnish on the parts that touch skin, and renew it when it wears.
- Choose earrings with titanium or stainless steel posts, since earlobes react most often.
- Prefer designs that sit on clothing, like long pendants, over pieces that rub skin.
When to see a doctor
If a rash spreads, blisters, or does not settle within a few days of removing the jewellery, see a doctor or dermatologist. A patch test can confirm a nickel allergy, and they can recommend appropriate treatment. Do not keep wearing a piece that causes a reaction.
Reading product listings
Look for the stated material of both the main metal and any posts or clasps. Phrases such as 'stainless steel', 'titanium steel' or '316L' are more reassuring than 'alloy'. Note that 'nickel-free' and 'hypoallergenic' are not regulated terms everywhere; if you have a confirmed allergy, choose pieces where the material is clearly stated, and ask the seller if unsure.
Earrings and new piercings
Earlobes are the most common place for jewellery reactions because posts sit inside the skin. For new or sensitive piercings, wear titanium or surgical steel studs until the piercing is fully healed, and only then try fashion earrings for short periods. Clean posts with a little rubbing alcohol before wearing, and never share earrings.
Frequently asked questions
Is stainless steel safe for nickel allergy?
316L stainless steel is tolerated by most people with nickel sensitivity because it releases very little nickel, but highly sensitive people may still react.
Why does my ring turn my finger green?
Copper in the metal reacts with sweat and lotion and leaves a harmless green mark. Keeping the ring dry and clean reduces it.
Can I become allergic to jewellery later in life?
Yes. Nickel allergy can develop after repeated exposure, even if you wore the same jewellery without problems before.
