It helped SO much with my nickel allergy! I had large ulcers in my lower abdomen that were itchy for several days and would not go away. I even wore high-waisted underwear to try to cover up the affected area! But then I found this belt and now my skin feels great and I can wear any underwear I want again and not have to worry about rashes and nickel scars! This is one of my best purchases of the whole year!
