: As shown in this review, numerous analytical methods have been included to distinguish pigments in tattoo, paint, and ink items. The selection of method was depend upon the purpose, e.g. quantification or identification of pigments only. The introduction part in this review focuses on describing the importance to set up a pigment associated safety profile. Different degradation chemical substances formed as well as impurity trends can be indicated by doing a chemical investigation of pigments in tattoo products. It is noteworthy, the pigment recognition in tattoo inks can work as a preliminary method to identify the pigments in a patient's tattoo before removed by laser therapy. Contrary to the study of forbidden pigments, the identification process would usually require just a few indication substances for positive dye. In general, the tattoo pigments are almost insoluble in aqueous solution and lots of organic solvents, various pigment analyzes have been identified and assessed. It is proposed that in the future, laboratories concerned with tattoo substance analysis should have access to extensive pigment specifications and spectroscopic databases. The most important and recent physiological side effects of tattooing have been discussed in this review.
