The definition of Body Art

According to Wikipedia:

Body art is art made on, with, or consisting of, the human body. The most common forms of body art are tattoos and body piercings, but other types include scarification, branding, scalpelling, shaping (for example tight-lacing of corsets), full body tattoo and body painting.

More extreme body art can involve things such as mutilation or pushing the body to its physical limits. For example, one of Marina Abramović's works involved dancing until she collapsed from exhaustion, while one of Dennis Oppenheim's better-known works saw him lying in the sunlight with a book on his chest, until his skin, excluding that covered by the book, was badly sunburned. It can even consist of the arrangement and dissection of preserved bodies in an artistic fashion, as in the case of the plastinated bodies used in the travelling Body Worlds exhibit.

Body art is also a sub-category of performance art, in which artists use or abuse their own body to make their particular statements.
