That's the risk of getting a tattoo.

Now, a new study has found that tiny metal particles from the tattoo needle enter your skin and travel toward the lymph nodes.

Researchers at the European Synchroron Rating Institute (ESRF) in France found that nicle and chromium are fired by tattoo needles when using a certain pigment.
The white pigment is called titanium dioxide, and often mixed in bright colors such as blue, green and red, transmits “Tch”.

The team thinks these heavy metals can explain why some people have bad reactions to tattoos and aim to investigate the further health effects of metal, potentially toxic, caused by tattoos.

A 2015 study conducted by New York University surveyed 300 tattooed people, and more than 10 percent reported that they had a strong allergic response.

Initially, most experts blamed paints, but the team at the ESRF found that metal particles were in the lymph nodes of tattooed people and were trying to find a link.

We were continuing our previous study, trying to find the connection between iron, chromium, nicotine and dyeing. After we studied several human tissue samples and found metal components, we realized that there must be something else... then we thought about testing the needle and this was our moment of cereeka, said one of the scientists.
