00:00Tattoo ink may not stay where you put it.
00:02When ink goes into the skin, the body treats it as a foreign substance.
00:06Immune cells try to clear it, but the particles are too large.
00:09That is why tattoos are permanent.
00:12Research shows ink particles can also travel through the lymphatic system.
00:16They can build up in the lymph nodes, which help run your immune defense.
00:20Some inks contain trace metals such as nickel, cobalt, chromium, and rarely, lead.

00:30Black inks can contain compounds found in soot.
00:32The long-term health effects are still unclear.
00:35Scientists say they are only beginning to understand them.
