Researchers found that while most inks are considered non-toxic, specific chemical compounds can provoke allergic reactions or even systemic inflammation in rare cases. The findings raise questions about regulatory oversight and the need for clearer labeling in tattoo studios. Experts now urge both artists and clients to be more vigilant about ink ingredients and aftercare practices.
