Previous reports have shown that several tattoo inks available on the Swedish market contain prohibited substances. Although the regulatory framework has been in place since 2012, there is a lack of clarity about whether the contents of tattoo inks meet regulatory requirements or not. The purpose of this study was to find out if an active supervision is conducted to determine if the regulations on tattoo inks are met, focusing on the content of prohibited substances. 43 Swedish municipalities were given a survey about their experiences in conducting supervision of tattoo artists. Most municipalities have used the regulation (2012:503) on tattoo inks. Parts that involves giving information to the customer, labeling of tattoo ink containers and sterility have been more common in the supervision than the parts related to control of the tattoo inks content. It is today difficult and time consuming to verify the state of tattoo ink contents and to compare with the available lists included in the legislation. The study suggests the introduction of a simpler, standardized method for investigating whether a tattoo color contains prohibited substances or not.
