A tattoo is a form of body modification where a design is made by inserting ink, dyes and pigments, either indelible or temporary, into the dermis layer of the skin to change the pigment. Tattoos fall into three broad categories: purely decorative (with no specific meaning); symbolic (with a specific meaning pertinent to the wearer); pictorial (a depiction of a specific person or item). Tattoos have historically been regarded in the West as ‘uncivilised’, and over the last 100 years the fashion has been associated mainly with sailors, working men and criminals. By the end of the 20th Century many Western stigmas of the tattoo culture had been dismissed and the practice has become acceptable and accessible for people of all trades and levels of society.
