That being said, the ink you observe oozing throughout the healing process is part of the surplus ink that your tattooist put. It's made up of ink, blood, plasma, perspiration, and other physiological fluids. So, everything is normal, everything is to be anticipated, and there is nothing to be concerned about. However, if the leak continues past the initial few days after getting a new tattoo, then you should probably contact a professional tattoo artist. The reasons your tattoo might be leaking ink are similar to why any other type of skin injury would bleed: the ink has broken the surface of the skin, so it has freedom to flow out. As the ink flows under the skin's surface, it will eventually reach an area of capillaries where it can drain back into the body. But some of it will also connect with larger vessels such as blood veins or lymph nodes, which may cause some color to spread beyond the original site of the injury. If you're worried about how your tattoo is healing, ask your tattoo artist for advice about what kind of cover-up might be needed and whether or not it's necessary to remove the entire tattoo. But don't worry about small amounts of leakage; it is very common after getting a new tattoo.
