What’s Actually In Your Tattoo Ink? No One Really Knows

Nearly a third of U.S. adults have tattoos, but how many people
know what's really in the ink? Despite new regulations, researchers
have found many commercial inks contain unlisted and potentially
harmful ingredients. John Swierk, an assistant professor of
chemistry at Binghamton University, and his team are trying to
figure out exactly what goes into each vial of tattoo ink—and how
tattoos actually work—to help make body art safer. Email us at
