Tattooing, which is defined as the permanent insertion of ink or other pigments below the skin using a sharp instrument, has been used for cosmetic and ritual purposes since the Neolithic era. It has been used to identify criminals, invoke magical powers and, most recently, to adorn the skin with colorful designs in what has become a major trend.Indeed, a recent telephone survey done by the American Academy of Dermatology reports that 36 percent of people between the ages of 18 and 29 are tattooed, and 24 percent of people between the ages of 18 and 50 have been inked. This represents a 16 percent increase over a similar survey done in 2003!
