Why do some people have an allergic reaction to jewelry?
Nickel is usually the culprit with skin allergies. That is a metal commonly found in white gold jewelry as well as costume jewelry. You won’t just have discolored skin. You may also have a rash, bumps or itchy skin where it comes into contact with the metal. With rings, sometimes soap or water may cause the irritation. Be sure to dry the area well where the ring comes into contact with your skin.
