Tattoos are becoming a more popular art form amongst younger generations. About 24% of Americans have one or more tattoos. Most tattoo inks are made from organic materials and are subdivided into two main classes of organic pigment are in us in tattoo and permanent make-up inks: azo pigments and polycyclic pigments1 PPD or p-Phenylenediamine is a chemical agent used as a coloring dye; it has also been known to cause allergies2, 3. Coloring agents, such as PPD is notoriously known for speeding up dyeing, improving pattern definition, to darken its red appearance in tattoos2. PPD is one amongst many other toxic aromatics that azo compounds can decompose into. This research focuses on the current literature studies assessing the toxicity of the pigments in tattoo inks that can decompose from overexposure to ultraviolet radiation from the sun.
