Tattooing has long been practised in various societies all around the world and
is becoming increasingly common and widespread in the West. Tattoo ink
suspensions unquestionably contain pigments composed of nanoparticles, i.e.,
particles of sub-100 nm dimensions. It is widely acknowledged that nanoparticles
have higher levels of chemical activity than their larger particle equivalents.
However, assessment of the toxicity of tattoo inks has been the subject of little
research and ink manufacturers are not obliged to disclose the exact composition
of their products. This study examines tattoo ink particles in two fundamental
skin components at the nanometre level. We use atomic force microscopy and light
microscopy to examine cryosections of tattooed skin, exploring the collagen
fibril networks in the dermis that contain ink nanoparticles. Further, we culture
fibroblasts in diluted tattoo ink to explore both the immediate impact of ink
pigment on cell viability and also to observe the interaction between particles
and the cells.
