When you get your ears pierced, exudate is released to heal the wound, which can react with metal and cause allergies. First piercings are particularly prone to this, and titanium earrings are the least likely to cause allergies. Resin-based earrings can promote bacterial growth, and even medical-grade stainless steel contains nickel and chromium, which can cause metal allergies. A point of caution is that even if only the post is titanium, allergies can still occur if the part that touches the earlobe is made of a different metal. Once an allergy develops, it can cause red rashes with necklaces, rings, etc. GOU earrings are made of titanium from the back of the stone setting to the post, ensuring safe wear. ※ References (Regarding allergenic substances contained in medical and general stainless steel) ※ 1 Journal of environmental dermatology and cutaneous allergology, 2012 ※ 2 Regarding the risk of developing metal allergies from nickel-containing earrings Journal of Environmental Dermatology and Cutaneous Allergology 2014 ※ 3 Epidemiological survey of patients suspected of metal allergies caused by dental metals Journal of Environmental Dermatology and Cutaneous Allergology 2014
