The study itself [0] makes a stronger claim: When any antigen breaches the skin barrier, the local immunologic response includes cell-mediated translocation of the antigen to the local lymph nodes from where a systemic immune response is initiated. The translocation of tattoo ink seems to be very effective; it has been estimated that 32% of the injected pigment is translocated after 6 weeks, and that as much as 99% may become translocated over time. In clinical settings, pigmented and enlarged lymph nodes have been described in tattooed individuals for decades. Translocation of both black and coloured tattoo pigments to human lymph nodes has been confirmed, as have depositions of metal particles from tattoo needle wear. That is - it's not just during the healing period, and that it's been confirmed rather than a hypothesis.
