Platinum is not allergic, don't worry. Because platinum is not only extremely pure, but also extremely stable in chemical properties, it will not be affected by contact with common acidic substances in life. Anyway, I will wear platinum jewelry normally, whether I exercise, swim or take a bath, but so far I have no allergic symptoms. So for sensitive muscles, platinum is really resistant! Generally speaking, most people who are allergic are alloys with low purity such as K gold, so just avoid sensitive muscles ~
