why does fake jewelry cause you to break out or get a rash?
In: 4
Nickel allergy, nickel is a relatively cheap metal which looks shiny resulting in contact dermatitis in some people.
From what I understand, fake jewellery is usually made from cheaper metals like copper, nickel or zinc. These can be painted, clad or coated to look like the metal they are trying to imitate but are often done poorly. More often than not, people experience a rash or a reaction with either the base metal or salts that form. For instant, copper can react with sulphur to form copper sulphides and more notably copper (II) sulphate is an irritant
Nickel is cheap and most people don’t know enough about jewelry and metal to tell when it’s nickel. So they use nickel. Some people have a nickel allergy. It’s the same logic as rubbing peanut oil on someone who’s allergic to peanuts
