It’s one of those things you might not even know is possible until it happens to you and you find yourself frantically googling “Why is my jewelry turning my skin green?” It’s actually a very common occurrence, and yes it’s the jewelry causing it and you are not turning into Shrek or the Hulk! The discoloration can be alarming and unsightly, but it’s usually harmless. Let’s discuss why some jewelry turns your skin green, the science behind this reaction, and how to prevent this unwelcome side effect.
Why Does Jewelry Turn Skin Green?
The green discoloration often associated with jewelry is typically caused by a chemical reaction between the metal in the jewelry and the acids or moisture on your skin. Here are the main culprits:
-
Copper
Copper is a common metal used in many types of jewelry, either as a base metal or in alloys. When copper reacts with sweat, oils, and the acidic environment of your skin, it forms copper salts, which are green. This is the most frequent cause of green skin from jewelry.
-
Alloys
Many pieces of jewelry are made from alloys, which are mixtures of metals. Common alloys include brass (copper and zinc) and bronze (copper and tin). These alloys can also cause a green discoloration due to the copper content.
-
Low-Quality Plating
Jewelry that is gold or silver plated can cause green skin if the plating wears off and the base metal (often copper or nickel) is exposed. Once the base metal comes into contact with your skin, it can react and form green compounds.
-
Nickel
Although nickel is more often associated with skin irritation and allergic reactions, it can also contribute to green discoloration when used in alloys with copper or other reactive metals.
The Science Behind the Green Discoloration
The green color is a result of a chemical reaction known as oxidation. Here’s how it works:
-
Oxidation of Copper: When copper in your jewelry comes into contact with oxygen, moisture, and acids from your skin, it undergoes oxidation. This reaction forms copper oxide, which further reacts with carbon dioxide and water to form copper carbonate—a green compound.
-
Acids and Moisture: The natural oils, sweat, and acidity of your skin can accelerate the oxidation process. The acids react with the copper to form copper chloride and other copper salts, which are green.
How to Prevent Jewelry from Turning Your Skin Green
-
Choose the Right Metals
Opt for jewelry made from non-reactive metals such as stainless steel, platinum, or high-karat gold (18k or above). Sterling silver is also a good option, but it can still cause green skin for some people due to its copper content.
-
Clear Coatings and Sealants
Applying a clear nail polish or a jewelry sealant to the parts of the jewelry that touch your skin can create a barrier that prevents the metal from reacting with your skin. Reapply the coating periodically as it can wear off over time.
-
Keep Your Skin and Jewelry Dry
Moisture accelerates the oxidation process, so try to keep your skin and jewelry dry. Remove jewelry before washing your hands, swimming, or exercising.
-
Clean Your Jewelry Regularly
Regular cleaning can remove the oils, sweat, and other substances that contribute to the oxidation process. Use a gentle jewelry cleaner or a mixture of mild soap and water, and dry the pieces thoroughly afterward.
-
Avoid Low-Quality Plated Jewelry
Invest in high-quality pieces with thicker plating or those made from solid metals rather than plated ones. High quality jewelry is less likely to wear down and expose reactive base metals.
Dealing with Green Discoloration on Skin
If you notice your skin turning green, don’t panic. The discoloration is harmless and can be easily removed:
-
Soap and Water: Wash the affected area with mild soap and warm water.
-
Vinegar and Water: Mix equal parts vinegar and water, then use a cotton ball to apply the solution to the green area. Rinse thoroughly.
-
Lemon Juice: Rub a bit of lemon juice on the green spot, let it sit for a few minutes, then rinse and wash with soap and water.
