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. The art of making tattoos is tattooing.
Tattoos fall into three broad categories: purely decorative (with no specific meaning); symbolic (with a specific meaning pertinent to the wearer); and pictorial (a depiction of a specific person or item). In addition, tattoos can be used for identification such as ear tattoos on livestock as a form of branding.
Body painting is a form of body art where artwork is painted directly onto the human skin. Unlike tattoos and other forms of body art, body painting is temporary, lasting several hours or sometimes up to a few weeks (in the case of mehndi or "henna tattoos" about two weeks). Body painting that is limited to the face is known as "face painting". Body painting is also referred to as (a form of) "temporary tattoo". Large scale or full-body painting is more commonly referred to as body painting, while smaller or more detailed work can sometimes be referred to as temporary tattoos.
