Scarification involves scratching, etching, burning, or superficially cutting designs, pictures, or words into the skin as a permanent body modification. Unlike with regular tattoos, the outcome of scarification is always unpredictable, depending on variables, such as skin type, cut depth, how the wound is treated while healing etc. While some people undergo this rather brutal procedure in order to gain an original body decoration, others may also do it to experience a euphoric state that the endorphins released during the act can induce.
