Tattoos contain nanoparticles that reach the lymph nodes

This is the conclusion reached by the authors of a study in which analyzes were carried out on the components used in tattoos. A group of scientists from Germany and the ESRF, meeting in Grenoble (France), have explained that tattoo ink is made up of elements in micro and nanoparticle forms that become lodged in the lymph nodes. They are organic and inorganic pigments, as well as toxins.

Hiram Castillo, one of the authors of the study and a scientist at the ESRF, explained: “When someone wants to get a tattoo, they are usually very careful in choosing a salon where sterile needles that have not been used before are used. “On the other hand, no one checks the chemical composition of colors, but our study shows that they would have to.”

In addition to organic pigments, the inks used also contain preservatives and polluting products such as nickel, chromium, manganese or cobalt. In addition to carbon, used to give dyes a black color, titanium dioxide is also used, a white pigment used to make certain shades when combined with certain dyes. Titanium dioxide is also used as an additive in certain foods, sunscreens and paints.

Bernhard Hesse, one of the first authors of the study and a scientist at the ESRF, says: “We already knew that tattoo pigments traveled to the lymph nodes due to visual evidence. The lymph nodes are stained with the color of the tattoo. It is the body’s response to cleaning the tattoo entry site. What was not known is that they do so in a nano form, which implies that they cannot have the same behavior as particles at a micro level. And that’s the problem, we don’t know how nanoparticles react.

The study used X-ray fluorescence measurements, which made it possible to locate titanium dioxide in its two ranges, micro and nano, in the skin and lymph nodes. In the skin the particles are small in size, but they are micro particles, but in the lymph nodes the problem is aggravated as they are nanoparticles, the exact harmful nature of which is not yet known. The evaluation of the biomolecular changes in the tissues close to the tattoos will serve to understand in detail the scope of these particles.

Skin inflammations caused by tattoos are not the only harm they cause, as you can see there are even more. Research will continue to understand in detail the adverse effects and their relationship with the chemical and structural properties of the pigments used in tattoos.
