It is almost always nickel
Nickel is the most common cause of allergic contact dermatitis from jewelry, and it is extremely widespread because it is cheap and it makes alloys harder and brighter.
A nickel reaction typically shows up as redness, itching, and sometimes weeping or crusting where the metal sits. It can develop at any point in life, including to a piece you wore comfortably for years — sensitization builds with exposure.
Because earrings put metal through broken skin, ears tend to be where people notice it first and worst.
"Hypoallergenic" is not a regulated term
This is the part worth internalizing. In the US, "hypoallergenic" has no standardized legal definition for jewelry. Any seller can print it.
It is a marketing word, not a specification. What actually tells you something is the named metal — which is why a listing that says "316L stainless steel" or "titanium posts" is more useful than one that says "hypoallergenic", and why every piece I sell names its metal on the product page.
Which metals are genuinely safer
- Titanium and niobium: the safest options. Implant-grade titanium is what is used for surgical implants, and it is the standard recommendation for badly reactive ears and fresh piercings.
- Platinum: essentially inert, and priced like it.
- Surgical stainless steel (316L): tolerated by the large majority of people with nickel sensitivity. Important honesty here — 316L is not nickel-free. It contains nickel, but the alloy binds it tightly so very little is released onto skin. If you are severely nickel-allergic, it can still be a problem for you.
- Solid gold at 14k or higher: generally well tolerated. Lower karats contain more alloy metal, and that alloy may include nickel — white gold in particular is often nickel-alloyed.
- Sterling silver: usually fine. It is 92.5% silver with the balance typically copper, though nickel does appear in some cheaper alloys.
What to be cautious with
Unspecified "alloy", "base metal", "surgical steel" without a grade, and inexpensive plated costume jewelry where the base is unknown. Plating is the specific trap: a piece can be entirely comfortable when new and start reacting months later, once the plating wears through and the base metal reaches skin.
That is the same wear mechanism described in the tarnish guide, with a more personal consequence.
Practical steps
- Buy from sellers who name the actual metal rather than an adjective.
- For a new piercing, or ears that react to almost everything, start with implant-grade titanium.
- Take earrings out before showering and sleeping. Moisture trapped against the post makes reactions worse.
- Clean posts regularly — buildup irritates independently of any metal allergy.
- If a piece you already own reacts, a jeweler can often swap the posts or findings for titanium rather than you losing the piece.
What I use
My pieces are mostly gold-plated stainless steel, with some gold-plated brass, bronze and sterling silver depending on the piece, and the metal is named on every product page.
If you have a known metal sensitivity, message me before ordering and I will tell you exactly what a given piece is made of, findings included. If it is not a good match for you I would genuinely rather say so than sell you something you cannot wear.
Common questions
Is stainless steel good for sensitive ears?
For most people with nickel sensitivity, yes. Surgical 316L stainless steel contains nickel but binds it tightly in the alloy, so very little reaches skin. It is not nickel-free, so people with severe nickel allergy may still react and are better served by titanium.
Is gold-plated jewelry safe for sensitive ears?
It depends on what is under the plating, and on how worn the piece is. While the gold layer is intact, you are in contact with gold. Once it wears through, you are in contact with the base metal — which is when people often start reacting to a piece that used to be fine.
What is the safest metal for pierced ears?
Implant-grade titanium, followed by niobium and platinum. These are the standard recommendations for fresh piercings and for people who react to most metals.
Does hypoallergenic mean nickel-free?
No. The term is not regulated for jewelry in the US and carries no guarantee. Look for the named metal and alloy grade instead.
