But body art enthusiasts might face potential risks from a source they don't expect.

Tattoo ink Inks themselves.

Up until recently, tattooings were totally unregulated in the United States.

In 2022, the federal government pulled tattooings under the regulatory umbrella of cosmetics, which means the Food and Drug Administration can oversee these products.

Some of these additives are simply compounds that should be listed on the packaging and aren't.

But others could pose a risk to consumers.

For science quickly, I'm Rachel Feldman. I'm joined today by John Swirk, an assistant professor of chemistry at Binghamton University, State University of New York. His team is trying to figure out exactly what goes into each vial of tattooing, and how tattoos
