Laser Tattoo Removal: Benefits and Caveats

The amateur tattoo can be done by any sharp object like a needle or a sharp piece of bone. The professional tattooing technique depends on the country where the tattoo is performed. In Japan, the artist usually uses needles put together into a wooden handle, called hari, while for the Polynesian technique uses a sharp rake held by a handle that the artist will tap using a rigid piece of bamboo. In the western world the artist will use preferably the electric tattooing machine developed by Riley at the end of the 19th century. It consists of an electric motor driving a crankshaft similar to that of a sewing machine, which operates a metal stylus with a single needle or array of needles at its tip. The pigment is injected just below the epidermis and within ten to fourteen days tends to migrate deeper into the dermis for as an yet unknown reason. Introduction
