Black marks on skin caused from gold?

Gold, in its pure form (24k), is considered hypo-allergenic, meaning that it is less likely to cause allergic reactions than other metals used in jewellery. However, it is possible for some individuals to develop an allergy to gold, particularly if the gold is not of high purity. Additionally, certain impurities or substances found in gold jewellery, such as nickel, copper, or zinc, can also cause skin reactions and discolouration.

Some people may also experience skin discolouration or black marks after wearing gold jewellery, especially if the jewellery contains a high amount of copper. Copper can react with sweat, oxygen, and other substances on the skin to form copper oxides, which can cause a greenish-black discolouration on the skin. This reaction is more common in individuals with naturally acidic skin or those who perspire heavily.

To minimise the risk of skin discolouration or allergic reactions, it is recommended to:

Choose high-quality gold jewellery made from pure 24k gold or opt for gold jewellery that is labelled as "hypoallergenic."Avoid jewellery that contains high amounts of copper or other reactive metals.Clean your gold jewellery regularly to remove dirt, sweat, and other substances that may cause skin irritation.Rinse your skin with water and pat it dry after wearing gold jewellery to remove any residual sweat or substances.If you experience any skin discolouration or irritation, stop wearing the jewellery and consult a dermatologist.
