Tattoo needles leave behind metal particles that spread to lymph nodes, study finds

The video discusses the findings of toxicology research on tattoo needles, which deposit metal particles like nickel and chromium into the skin. These particles are transported to the body's lymph nodes, with sizes ranging from 50 nanometers to two micrometers. Researchers used scanning electron microscopy to analyze tattoo needles before and after use, discovering abrasions caused by inks containing titanium dioxide. This effect was not observed with carbon black ink.

What metals are deposited into the skin by tattoo needles during the tattooing process?

• Zinc and Lead
