Professional tattooists rely primarily on the same pigment base found in cosmetics. Amateurs will often use drawing inks such as low grade India ink, but these inks often contain impurities and toxins which can lead to illness or infection.
Studio hygiene
The properly equipped tattoo studio will use biohazard containers for objects that have come into contact with blood or bodily fluids, sharps containers for old needles, and an autoclave for sterilizing tools. Certain jurisdictions also require studios by law to have a sink in the work area supplied with both hot and cold water.
