In brief: Skin allergy test

Before you use a dye product, you should follow the instructions in the package to do a allergy skin patch test.
Apply a small amount of dye on your arm, keep it dry by covering it with a bandaid, check it in 48 and 72 hours to make sure you didn't react with redness or swelling. If not, this dye is safe to use.
