Tattoo ink is generally permanent. Tattoo removal is difficult, painful, and the degree of success depends on the materials used. Recently developed inks claim to be comparatively easy to remove. Unsubstantiated claims have been made that some inks fade over time, yielding a "semi-permanent tattoo."
In the United States, tattoo inks are subject to regulation by the U.S. Food and Drug Administration as cosmetics and color additives. The FDA and medical practitioners have noted that many ink pigments used in tattoos are "industrial strength colors suitable for printers' ink or automobile paint."
