The Finnish Safety and Chemicals Agency (Tukes) examined the safety of tattoo and permanent make-up inks. Tukes had a total of 20 tattoo and permanent make-up inks tested. Eight of the tested inks contained chemicals that may cause cancer and be toxic for reproduction: various aromatic amines, polycyclic aromatic hydrocarbons, or heavy metals. Tukes contacted companies that sell inks and requested that they withdraw any tattoo inks that are hazardous to health.
