What specific common household metal allergen is frequently cited as causing localized rashes after repeated exposure, often found in jewelry?
Answer
Nickel alloys
Environmental factors within the household environment often hide potential sensitizers that contribute to rash development over time, sometimes resulting in a sudden flare-up. Among these culprits, metals used in accessories are noteworthy. Jewelry, snaps on clothing, or zippers frequently incorporate nickel alloys, which act as a very common contact allergen. The resulting rash is typically localized to the area where the metal repeatedly touches the skin, appearing after repeated rather than singular exposure.
