OSCO EAR EDUCATION

Why do earrings turn your ears green?

If you’ve ever taken out a pair of earrings and found a green mark underneath, you’re not imagining it. The reason usually comes down to what your jewellery is made from.

Find out why

The problem

The upgrade

There’s a reason this happens. It could be what your earrings are made from.

THE SHORT ANSWER

It’s usually the metal.

Green marks can happen when certain metals in your jewellery react with moisture, sweat and the air around them.

Plated jewellery can also wear over time, exposing the base metal underneath.

01 ◉

The metal

Some earrings use copper-containing base metals or plating over another metal underneath.

02 ＋

Add moisture

Sweat, water, skincare and everyday wear can all come into contact with your jewellery.

03 →

The reaction

The metal can oxidise and leave green or dark discolouration behind on the skin.

Green skin doesn’t automatically mean an allergy.

The colour can simply be caused by a reaction between the metal and your skin. It’s still a pretty good reason to know what your earrings are made from.

× Plated / unknown metals

Looks can be deceiving.

A gold-coloured finish doesn’t necessarily tell you what the jewellery underneath is made from.

× The base metal may not be obvious

× Plating can wear with repeated use

× Some metals can oxidise and leave marks

01 Why do earrings turn my ears green?

Green marks are often caused when metals such as copper react with moisture, sweat or products on your skin. This can happen with some alloys and plated jewellery.

02 Does green skin mean I’m allergic to my earrings?

Not necessarily. Green discolouration can simply be the result of a metal reacting with your skin or moisture. Irritation, itching or soreness can have other causes, so persistent symptoms are worth getting checked by a professional.

03 Why does OSCO use implant-grade titanium?

Implant-grade titanium is lightweight, highly corrosion resistant and widely used for piercing jewellery. It’s why it’s the material our professional piercing team chooses for OSCO pieces.

04 Can I wear titanium earrings every day?

Titanium’s light weight and resistance to corrosion make it a practical material for everyday piercing jewellery. Always make sure your jewellery is correctly sized and your piercing is suitable for the piece you’re wearing.
