I've blogged about temporary tattoos that could bring on allergies, and now, according to the CourierPost Online, the popularity of body piercing has led to a rise in nickel allergies.

Nickel is often one of the metals present in piercing jewelry, and it can cause severe allergic contact dermatitis, or eczema.

If you have nickel allergy, use the Nickel Solution kit to test for nickel content; the kit also allows you to wear jewelry that would otherwise cause a reaction.
