Podcast #269: Tattoo Ink Complications

Author: Michael Hunt, M.D.

Educational Pearls

• Tattoo ink is applied below the skin, and because of this, they can lead to keloids, granulomas, tetanus, hepatitis B and C, and skin infections.
• Tattoo pigment has been found to contain substances like lead, cadmium, chromium, and arsenic; however, there are no long-term studies of the health effects of tattoos.
• In one study 14% of inks had ingredients that were banned in cosmetics.
• Nanoparticles of tattoo pigment can be found in the lymph nodes, and laser removal can precipitate their spread.
• Those with tattoos could experience complications with MRI because of the metal content of the ink.
