Abstract Background It is estimated that more than 60 million people in Europe, that is, around 12% of the European population, have at least one tattoo. However, there is still little information on the long‐term effects of tattoos. Inks used for tattooing are a mixture of chemicals, with pigments being the main components responsible for the visual effect. The pigments used are not produced specifically as ingredients for tattooing, but mainly/primarily for the needs of industry, where lower purity requirements and quality standards are acceptable. It is therefore necessary to understand the risks associated with tattoos, but also to implement appropriate legal regulations. The aim of this article was to collect and summarise the results of research conducted so far on the type of colourants used in tattoo ink and to analyze the impact of these on human health. In addition, as part of this work, the current legal acts regulating the concentration limits and composition of inks used in tattooing as well as the psychological aspects of tattooing were collected and presented. Methods Scientific reports and articles from renowned journals from 1994 to 2022, relevant review and research publications in PubMed, and Google Scholar were analyzed. To analyze the available research literature, the Web of Science, Scopus, PubMed databases were used. The following keywords were used to search for publications: tattoos, colourants used in tattoos, side effects of tattoos, legal acts, psychological aspects of tattoos. Results The result of the literature analysis indicates a risk to health and side effects associated with tattooing the body. There are still no standardised test methods to analyze tattoo inks and assess their safety. Although the art of tattooing has been known for millennia, European legal authorities have not yet implemented effective regulations. Currently, tattoo products in Europe are covered by the general REACH regulation (Resolution ResAP, 2008; EU regulation 2020/2081, 2020). on product safety. The new amendment in force since January 4, 2022 introduces concentration limits for certain substances used in tattoo and permanent makeup inks. However, these provisions do not sufficiently protect either the consumer or the tattoo industry. Conclusions The results of the research indicate a potentially harmful effect on skin health. A more stringent safety assessment of the colourants used for tattooing is recommended, supported by studies and applicable legislation. |
