Tattoo frequently asked questions

They can: it depends on the pigment and formula. Inks use organic and mineral pigments; some contain copper, iron or titanium, for example. A metal-containing compound is not the same as a metal shaving. Trace metals can also occur as impurities, including in black inks.

Tell your artist about known allergies before the session so the specific ink can be checked and discussed with your dermatologist.
