It’s not news that tattoos are hitting the mainstream, but a new study reported in the journal Scientific Reports reveals that tattoo inks’ nanoparticles are adding color to other parts of your body.
As the tattooed population knows all too well, the process of tattooing consists of placing insoluble deposits of pigmented ink just below the epidermis, or outermost layer of skin. As they also know, your body does pretty much anything it can to get that ink out — which is why new tattoos excrete ink, plasma, and lymphatic fluid through the epidermis while healing.
