If you’ve been tattooed in the US, the ink under your skin may have more components than you previously imagined, a new study reveals.
The study, conducted by Binghamton University and titled “What’s in my ink: An analysis of commercial tattoo ink on the U.S. market,” shows discrepancies between the ingredient labels on tattoo ink and the actual substances in the bottle.
When doctoral student Kelli Moseman—the article’s lead author—and researchers Ahshabibi Ahmed and Alexander Ruhren noted that the tattoo inks they were analyzing contained substances that weren’t on the label, they wondered whether the difference was a result of the ink’s interaction with light.
