New research involving mice reveals that tattoo ink particles rapidly migrate into lymph nodes shortly after application, where they remain detectable for extended periods. The study found that the pigments provoked immune cell death and sustained inflammation, while also impairing the body’s response to an mRNA-based COVID-19 vaccine. Scientists warn these findings could have broader implications for immune function and vaccine efficacy in tattooed individuals. The results highlight a previously understudied interaction between cosmetic pigments and the immune system.
