Despite stricter regulations, Europe has issues with tattoo ink ingredients
Briefly

A recent analysis has shown that 90% of tattoo inks in the US have serious labeling discrepancies, raising concerns about allergens and harmful additives.
Swierk’s team's findings revealed that while 10 examined tattoo inks were meant for the European market, nearly all did not meet EU regulations, highlighting significant safety and consumer protection issues.
The inherent challenge lies in the reliance on Raman spectroscopy for identifying tattoo pigment structures, as the technology proved unreliable in distinguishing between the three forms of a banned pigment.
The European Commission's crackdown on harmful tattoo ink ingredients emphasizes the importance of stringent regulations, contrasting sharply with the comparatively lax oversight in the United States.
