I was 35 when I first became allergic to "cheap earrings"!
Since then I have become allergic to a lot of metal things (jeans rivet, backs of buckles, etc). I have to be careful with soap, washing liquids, shampoos, etc, or I come out in little spots.
From about 5 years ago (I'm now 72) I have become allergic or, at least very sensitive, to adhesives. Normal Elastoplast, patches (medical ones I have to use), and now denture fixtures adhesives. That's a real problem!
Hello. It would be worth getting a referral for patch testing which can identify / confirm triggers for allergies as well as informing you about which products might be tolerated.
