However, many people worry that wearing jewelry will cause skin allergies. What if I have allergies? How can I prevent allergies? Which jewelry is not easy to be allergic? Health experts give you advice on pearl necklaces. How to deal with allergies? Case: Ms. Wang spent nearly 2000 yuan on a pearl necklace in a shopping mall half a month ago. After wearing it for less than two days, her neck felt itchy. People often say that pearls are warm and nourishing. Ms. Wang had never been allergic before wearing jewelry. Is there anything wrong with the quality of jewelry? Expert diagnosis: Some pearls, jadeites and other necklaces currently on the market may be allergic to some consumers after wearing them. The key to allergy is the metal material at the joint of the necklace. Generally, some cheaper metal alloys are used, such as copper alloy, aluminum alloy, iron alloy, etc., and do not contain precious metals such as gold and silver, which may easily cause human skin allergies. Tips: For high-grade jewelry, in order to prevent allergies, the necklace interface generally uses 18K gold. Ms Wang Can found a jeweler to replace it with a gold or silver interface. Because the materials are expensive, she still needs to pay a certain fee. You can also go to Sun Gold Store, Century Yuan, Zhou Dasheng and other professional gold stores to customize the interface. Consumers are not allergic to precious gems such as pearls and natural jadeite, so they can wear them with confidence. Wearing earrings, how to prevent allergies? Case: Miss Zhang, who likes fashion, bought an exaggerated tremella nail in a small jewelry store three days after her ears were pierced. Unexpectedly, the earlobe began to itch, burn and swell after she put it on. Because the silver needle was inserted after the hole was punched, it didn't itch at that time. Why is wearing tremella nails allergic? Expert diagnosis: There are two kinds of silver ornaments on the market at present. One is very cheap silver-plated jewelry, which is very easy to cause allergies after the silver-plated layer falls off. The other is 925 silver, which contains more than 92.5% silver, so most people are not allergic to silver, while the other 7.5% alloy contains copper and zinc, which may cause allergies, even if it contains chromium and nickel, it is easy to cause skin diseases. Tips: Pay special attention to earrings and other jewelry that need to pierce the skin, and try to buy jewelry with high precious metal content, such as pure gold, PT950, Pd 950 and Pd 990. People are generally not allergic to these metals. If you are allergic, try not to wear jewelry that pierces the skin. Ms. Zhang may have bought silver-plated or nickel-containing silver ornaments. It is suggested to go to the National Quality Inspection Center for Gold and Diamond Products to detect the content of precious metals. If the nickel content exceeds the national standard, it will be harmful to human health and should be discarded. In addition, I would like to remind you that you sweat a lot in summer, and jewelry should be cleaned frequently, especially before wearing earrings, which should be soaked in alcohol for disinfection. Note: 18K gold may also be allergic. Case: Miss Zhao just bought a 18K gold necklace, and soon after wearing it, she developed allergic symptoms such as itchy skin. 18K gold is a precious material. Why are you allergic? Expert diagnosis: some people's skin is sensitive to metals, and it is easy to be allergic when they wear it for a long time. There are relatively few people who are allergic to 18K gold, but 18K gold contains 75% gold, and the other 25% contains elements such as copper and zinc, which may cause some people to be allergic. Tip: If you have allergies, stop wearing them. Take it off and disinfect it with alcohol. You can keep wearing it after a while. If you are still allergic, you should wear jewelry with high precious metal content.
