Why does Sterling Silver turn my skin black?Updated 2 months ago

Why Your Skin Turns Black from Sterling Silver

Sterling silver is typically 92.5% pure silver and 7.5% other metals, usually copper. The reaction that causes skin discolouration is mostly due to oxidation and chemical interactions:

• Oxidation of Silver: Silver reacts with sulfur compounds in the air (or in your sweat), forming silver sulfide, which is black. This tarnish can rub off onto your skin.
• Reaction with Sweat: If your sweat contains more acidic compounds (like from certain diets, medications, or hormonal changes) a lower PH, it can accelerate tarnishing and cause the silver to leave marks.
• Copper Content: The copper in sterling silver can also react with moisture and acids, contributing to greenish or dark stains.
• Cosmetics & Lotions: Ingredients in makeup, lotions, or perfumes can interact with the metal and cause discolouration.
• Environmental Factors: High humidity, pollution, or even proximity to rubber or latex can speed up tarnishing.

How to Prevent It

• Keep Jewellery Clean: Regularly polish your silver with a soft cloth or silver cleaner.
• Avoid Moisture: Take off jewellery before swimming, showering, or exercising.
• Store Properly: Keep silver in airtight bags with anti-tarnish strips when not in use.
