Jewellery Rash: What Causes It and How to Stop It
A red, itchy patch where a necklace, ring or earring sits is one of the most common skin complaints in dermatology clinics. Most of the time it is one of two things: an allergy to a metal in the piece, or simple irritation from what gets trapped under it. The cause matters because the fix is different. Here is how to tell them apart and what to do about each.
Informational only: this is general medical information, not personal advice. A skin reaction that is severe, weeping, very painful or accompanied by fever needs assessment from a doctor. Persistent rashes should be patch tested by a dermatologist for a precise diagnosis.
What "jewellery rash" actually means
Jewellery rash is a layperson's term for two distinct medical problems that look similar but behave differently.
Allergic contact dermatitis (ACD) is a delayed type IV hypersensitivity reaction. Your immune system has been sensitised to a specific molecule, most often nickel. Each subsequent exposure produces an itchy, often blistered red patch 12 to 72 hours after contact.3
Irritant contact dermatitis (ICD) is direct, non-immune damage to the skin barrier from chemicals, friction, occlusion or moisture. It does not require sensitisation. Anyone exposed to the trigger for long enough will react.3
Both can show up as redness, dryness, scale and itching exactly where the jewellery sits. The clue to which is which usually comes from timing, repetition, and whether removing the piece (without changing anything else) settles it.
Cause 1: Nickel allergy
Nickel is the single most common cause of contact allergy in the world. A 2025 systematic review and meta-analysis of 79 studies and over 280,000 participants in Contact Dermatitis reported pooled prevalence at 17.6% in women and 5.7% in men.1 A 2018 European general-population study (the EDEN Fragrance Study) found 17.6% of women and 4.6% of men reacted to nickel on patch testing, and ear piercing was a significant predictor of sensitisation.4
Nickel ions cross the skin and trigger T cells
When jewellery comes into contact with sweat or moisture, free nickel ions are released. These ions penetrate the skin, bind to proteins, and become recognised by sensitised T cells. The result is a delayed inflammatory reaction at the contact site, typically peaking around 48 hours.
The EU REACH limit is 0.2 µg/cm² per week
EU REACH Annex XVII Entry 27 limits nickel release from jewellery and items in prolonged skin contact to 0.2 micrograms per square centimetre per week.5 Pieces that exceed the limit are not legally sold for prolonged skin contact in the EU and UK, but the limit is widely missed in cheap fashion jewellery and unverified imports.
Itchy, eczema-like rash that recurs
The rash appears 12 to 72 hours after wearing the same piece, even if it was previously fine. It is intensely itchy, often shows tiny blisters, and can spread slightly beyond the contact area. Healing leaves a faint discolouration or dryness for a few weeks.
Cause 2: Other metal allergies (cobalt, palladium, chromium, gold)
Less common but well-documented. Many people who react to nickel also react to cobalt or palladium because the alloys often appear together.
Frequently co-sensitises with nickel
Cobalt is used in some white gold and stainless steel alloys. Around half of people sensitised to cobalt are also sensitised to nickel, which is why jewellery rashes often persist even after switching from nickel-containing pieces if the new metal contains cobalt.
Common in white gold and dental work
Palladium allergy is increasingly recognised, and many palladium-allergic patients are also sensitised to nickel. Some white gold alloys use palladium instead of nickel for whitening, which is helpful for nickel-allergic wearers but does not solve the rash for everyone.
Mostly an issue with stainless steel and leather
Chromium allergy presents with similar redness and itch and is sometimes misattributed to nickel. Stainless steel alloys release small amounts of chromium and nickel, especially in moist conditions.
Real but uncommon
True gold allergy exists but is rare in everyday wear. Most "gold reactions" turn out to be reactions to copper, nickel, or other alloying metals in low-karat or plated gold pieces, not to gold itself. Solid 14k or 18k nickel-free gold is well tolerated by most patients with metal allergy.
Cause 3: Irritant contact dermatitis
Not every jewellery rash is allergy. Irritation from physical or chemical contact under the piece is just as common, and it can happen to anyone given the right conditions.
Mechanical rubbing erodes the skin barrier
Bracelets, rings and tightly-fitting necklaces can rub a healthy skin barrier raw, especially during exercise or in hot weather. Once the barrier is broken, even mild substances become irritating, which is why irritant rashes often start gradually.
Trapped sweat softens and macerates skin
A ring or earring back held against skin in damp conditions softens the keratin layer, raises pH, and creates a small environment where minor irritants become amplified. This is one reason rashes are more common in summer or after gym sessions.
Soaps, perfumes and lotions concentrate under jewellery
Hand soap, shower gel, perfume, hairspray, sunscreen and lotion can all sit underneath rings and earring backs and slowly damage the skin. The reaction is often misattributed to the metal when the real culprit is the residue.
Cause 4: Trapped soap, sweat, and sebum
This is a sub-type of irritant dermatitis specifically caused by what gets caught in the small space between the piercing and the back of the earring or under a ring.
A pale residue around the post or under a ring
That waxy, sometimes smelly residue is a mix of dead skin cells, sebum, soap scum and dried sweat. Left in place, it acts as a slow-release irritant. The lobe behind a friction back and the underside of a ring shank are the two most common sites.
Surface tension and limited airflow
Pieces that sit flush against the skin trap moisture and oils. The lobe is a particularly favourable site because sebum production is high and the piercing channel collects fluid.
Clean the jewellery and dry the area properly
Take the piece out, wash with mild soap and water, dry on a clean cloth, and rinse the skin with sterile saline. For a refresher, see our guide to cleaning earrings by metal type.
Cause 5: Plated jewellery wearing through
Plated pieces are a leading cause of new-onset earring rashes. The plating layer is initially safe, but it wears off over months or years to expose the base metal underneath, which is usually nickel-containing brass, copper or steel.
Every layer of the piece must be skin-safe
If the base metal is nickel-bearing, the piece is one layer of wear away from triggering allergy. The plating might survive water and showers, but micro-scratches from putting earrings on and taking them off allow nickel from the base to leach to the surface in moisture. This is the principle behind solid implant-grade titanium and solid 14k+ gold being more reliable for sensitive skin than any plating.
Replace plated earrings before they fail
If you notice the plating dulling, going patchy, or showing a different colour underneath, retire the piece. Wearing it past that point is the single most common preventable cause of recurrent earring rash.
How to identify which type of rash you have
| Feature | Allergic (ACD) | Irritant (ICD) |
|---|---|---|
| Onset | 12 to 72 hours after contact | Hours to a day, sometimes faster |
| Sensation | Itchy, sometimes burning | Sore, stinging or burning, less itchy |
| Appearance | Red, scaly, sometimes blistered | Red, sometimes shiny or chapped |
| Spread | Often slightly beyond contact area | Stays within contact area |
| Repeats with same piece? | Yes, every time | Only with same conditions (sweat, moisture) |
| Confirms with | Patch test by a dermatologist | Improves with barrier care alone |
If you are not sure, the most useful step is a patch test. UK dermatology services use a standard British Society for Cutaneous Allergy series that includes nickel sulphate, cobalt chloride and palladium chloride, which together identify the great majority of jewellery allergies.
How to stop a jewellery rash
The first step is always to remove the piece causing the reaction. Treatments after that depend on whether the rash is allergic or irritant, and how severe it is.
Remove the jewellery and rinse the area
Sterile saline (0.9% sodium chloride) is the gentlest rinse. Pat the area dry on a clean cloth. Avoid rubbing.
Use a plain emollient, not creams with fragrance
A simple emollient or ceramide moisturiser supports the skin barrier. Avoid scented lotions, antibacterial creams and home remedies, all of which can prolong the rash.
For a stubborn rash, see your GP
A short course of topical steroid (typically hydrocortisone 1% for the face and ear, or a stronger steroid prescribed by a doctor for thicker skin elsewhere) calms severe reactions. Do not self-prescribe potent steroids on the face or ear.
Switch to a confirmed-safe metal
For nickel allergy, the two reliable choices are implant-grade titanium (ASTM F136 or F67) and solid 14k or 18k gold confirmed nickel-free. Both are widely available and supported by decades of biomaterial and dermatology evidence.6
How to prevent jewellery rash long term
Take rings and earrings off before bed and the gym
The two highest risk windows are sleep (long contact, occlusion) and exercise (sweat, friction). Rotating between two pairs allows each to dry out properly.
Dry your ears properly after showering
Pat dry with a clean towel and let the area air briefly before re-fastening. Damp jewellery against damp skin is the perfect environment for both nickel release and irritant build-up.
Audit your collection once a year
Retire plated pieces that look worn. Keep a small set of confirmed-safe everyday earrings in implant-grade titanium or solid gold for the moments when you need to wear something for hours without thinking about it.
When to see a doctor
Spreading redness, swelling, warmth or fever
These suggest infection rather than allergy or irritation. Cartilage piercings can develop bacterial perichondritis that needs prompt antibiotic treatment.7 Seek same-day medical advice.
Weeping fluid or yellow or green discharge
Clear or pale lymph in the first week of a new piercing is normal. Thick yellow or green fluid is not. Get assessed.
Recurrent rashes despite changing jewellery
If the rash keeps coming back even after switching metals, ask for a referral to a dermatologist for patch testing. A precise diagnosis lets you avoid the actual culprit metal across all your jewellery and your hardware (zips, buckles, dental work).

How rhokea handles this
Rhokea was started by a doctor and a sensitive-skin patient. Every piece is built from ASTM F136 implant-grade titanium and finished with SkinPlating, our anodised titanium nitride layer. Both layers are independently waterproof and skin-safe, which is the all-layers rule in practice: nothing in the piece can leach nickel into the skin during long contact.
Independent Intertek Testing Services certification (December 2025) confirmed nickel release below 0.1 µg/cm²/wk on coated and uncoated rhokea surfaces, well under the EU limit of 0.2 µg/cm²/wk. Lead came in below 10 ppm and cadmium below 5 ppm. ASTM F136-13(2021)e1 composition was confirmed by the second report.
If your skin reacts to most earrings, our sleeper collection and flat back studs are the safest places to start: minimal contact area, no plating to wear through, and metal that does not release nickel into the skin.

What causes a rash from jewellery?
The two main causes of a jewellery rash are allergic contact dermatitis, almost always to nickel released from the metal, and irritant contact dermatitis from moisture, friction, soap residue or chemicals trapped under the jewellery. Less common causes include allergy to cobalt, palladium, chromium, or to coatings and adhesives applied to the jewellery.
How do I know if I am allergic to my earrings?
Allergic contact dermatitis to jewellery typically appears 12 to 72 hours after putting the earring in. The skin becomes red, itchy and sometimes blistered exactly where the metal touches it. Removing the jewellery improves the skin within a few days. A patch test by a dermatologist confirms which metal is responsible.
Is jewellery rash always nickel allergy?
No. Nickel is the most common cause, affecting roughly 17% of women and 6% of men in a 2025 global meta-analysis. But irritation from moisture, friction or trapped soap can look identical, and there are rarer allergies to cobalt, palladium and chromium. The pattern, timing and what you have been doing matter as much as the rash itself.
How do I stop a rash from earrings?
Take the earrings out, clean the area with sterile saline, and avoid creams unless prescribed. Switch to implant-grade titanium or solid 14k+ nickel-free gold once the skin has settled. Avoid the offending metal long term. Severe or weeping rashes need medical assessment because they can become infected.
Can a sterling silver rash be nickel allergy?
Yes. Sterling silver is 92.5% silver and 7.5% other metals, usually copper. Some sterling silver alloys contain trace nickel as a hardening agent, especially in cheaper or older pieces. White rhodium plating over silver can also wear away and expose nickel-containing base alloys.
Why does cheap jewellery give me a rash but real gold doesn't?
Cheap jewellery is usually base metal (often containing nickel) plated with a thin gold or silver layer. The plating wears off, exposing the base metal to skin. Solid 14k or 18k gold contains no nickel by EU regulations and does not corrode against skin, which is why real gold rarely triggers a rash.
What is the difference between an allergic and an irritant rash from jewellery?
An allergic (delayed type IV) rash takes 12 to 72 hours to appear, is intensely itchy, often spreads slightly beyond the contact area, and recurs every time you wear the same metal. An irritant rash usually appears faster, is more sore than itchy, sits exactly where the contact is, and improves once the trigger (moisture, friction, soap) is removed.
Is titanium safe for sensitive skin?
Yes. Implant-grade titanium (ASTM F136) is one of the most biocompatible metals known, used for joint replacements and dental implants. Confirmed allergy to titanium is extremely rare in the published literature, and it does not release nickel. It is the standard recommendation for people with diagnosed nickel allergy or recurrent earring rashes.
How long does a jewellery rash take to clear up?
A mild rash usually settles within 7 to 14 days once the offending jewellery is removed. Severe or weeping eczema can take 3 to 4 weeks and may need a topical steroid prescribed by a doctor. If the area becomes painful, swollen or oozing yellow or green fluid, get medical assessment because it may be infected.
Can I prevent a jewellery rash from coming back?
Yes. Identify which metals you react to, ideally through a dermatologist patch test. Switch your everyday earrings to implant-grade titanium or solid 14k+ nickel-free gold. Dry the ears properly after showering, avoid spraying perfume or hairspray near the piercing, and replace plated pieces before the plating wears through.
