What is in tattoo ink? Can I get a reaction from it?
Tattoo ink is actually not really ink but pigments derived from metal salts (and sometimes contain plastics) or synthetic organic dyes. Other ingredients typically include water, glycerin, and alcohol. There is no such thing as an FDA approved ink and generally are unregulated although some regulation is coming into effect in various parts of the globe. Ink Allergies are very extremely rare but do happen. Tattoo ink (while in bottle) should not be in contact with direct sunlight or heat and is usually not recommended for use near your eyes. If your concerned about getting an allergic reaction to tattoo ink, I would recommend asking your tattoo artist to do a test patch on you before you decide to get tattooed.
