Seamless prevention of adverse events from tattooing: integrated strategy emphasising the customer-tattooist...

The boom in tattooing has been paralleled by more frequent adverse events, which may be localised in the skin or systemic and manifested clinically or latent. Infections, allergic reactions from red-coloured tattoos and papulo-nodular reactions from black tattoos dominate. Mild complaints are very common, with 1/5 of all tattooed individuals having acquired sensitivity to sunlight in the tattooed skin. The potential risk of cancer due to potential carcinogens in some tattoo inks has hitherto not manifested in clinical reports, despite the millions of people who have been tattooed over many decades. A risk of death from tattooing remains associated with severe infection, i.e. sepsis. Preventive strategies may rely on focused preventions, and sterility and preservation of ink is essential, rational and knowledge-based. The chemical and particle contents of ink nanoparticles cannot be unrestricted; however, focused control of ink is facing many uncertainties, including analytical problems, lack of identification of allergens in ink and discrepancies between the content of potential carcinogens and manifestation of cancer in the clinic. The concept of seamless prevention is introduced as a pragmatic strategy that emphasises the customer-tattooist interaction, which is the 'engine' of tattoo safety. This strategy amalgamates the range of narrow-scope preventive instruments and shall ensure that any relevant instrument is used actively and without deficiency or drop out, thus resulting in a complete orchestration of a multi-targeted strategy. High-priority elements of this strategy shall facilitate a qualified 'go' or 'no go' decision by the customer before the tattoo is made and should involve informed consent, qualification of the tattooist and the parlour, including supplies of inks etc., and attention to hygienic security. Records and documentation of tattoo cases with complications and the culprit inks as well as the establishment of national or European-based surveillance systems that are properly equipped to deliver efficient clarification and handling of adverse events and hazards of tattooing and inks, which needs attention and timely action to prevent additional cases and epidemic outbreaks, are part of this seamless strategy, along with optimised medical therapy and research.
