The human body is the entire structure of a human organism and comprises a head, neck, torso, two arms and two legs. By the time the human reaches adulthood, the body consists of close to 100 trillion cells, the basic unit of life. These cells are organised biologically to eventually form the whole body.
Tattoo removal has been performed with various tools during the history of tattooing. While tattoos were once considered permanent, it is now possible to remove them with treatments, fully or partially.
Before the development of laser tattoo removal methods, commons techniques included dermabrasion, TCA (Trichloroacetic acid, an acid that removes the top layers of skin, reaching as deep as the layer in which the tattoo ink resides), salabrasion (scrubbing the skin with salt), cryosurgery and excision which is sometimes still used along with skin grafts for larger tattoos. Some early forms of tattoo removal included the injection or application of wine, lime, garlic or pigeon excrement. Tattoo removal by laser was performed with continuous-wave lasers initially, and later with Q-switched lasers, which became commercially available in the early 1990s. Today, "laser tattoo removal" usually refers to the non-invasive removal of tattoo pigments using Q-switched lasers. Typically, black and darker-colored inks can be removed more completely.
A temporary tattoo is a non-permanent image on the skin resembling a real tattoo. Temporary tattoos can be drawn, painted, or airbrushed, as a form of body painting, but most of the time these tattoos are transferred to the skin. Temporary tattoos of any kind are used for numerous purposes including self-expression and identification. For example, actors who wish to add to their character's distinctiveness might take temporary tattoos painted on the skin by hand or using stencils as part of their cosmetic ritual.
Old fashioned temporary tattoos, which were first made popular as inserts in bubble gum, were poor quality ink transfers that often resulted in blurry designs and could easily be washed or rubbed off. A very identifiable brand would be the fruit flavored chewing gum Fruit Stripe which has been popular with American children for many years. Nonetheless, these lick-and-peel temporary tattoos became a well-known piece of North America.
