Among friends we discuss whether gold is less allergenic than titanium and therefore better for ear piercing. Would you be so kind to give us the correct information.

Ans: If both metals gold and titanium contain the same amount of nickel, titanium is the best metal for ear piercing as titanium binds nickel better than any other metal, including gold. In other words titanium will will leak less nickel than any other metal, which means that titanium is less likely to cause nickel allergy.
