This involves scratching, etching, burning / branding, or superficially cutting designs, pictures, or words into the skin as a permanent body modification.
Strange utilisation of scar tissue. Though I can imagine there is divided opinions on this method of 'decoration'.
Nevertheless, I really enjoy how human this is - taking control of a natural process, through observation and creativity, and giving it another function. We are pretty cool!
Scar tissue is quite interesting, it’s different from normal skin tissue because the protein fibres arrange differently when healing, also the lack of hair follicles.
