Tattoo is a form of self-expression where permanent designs are inked onto the skin. The artist uses needles to deliver colored pigments into the dermis layer, creating a lasting image. Tattoos can be anything from tiny symbols to elaborate full-body murals, and hold a variety of meanings. They can serve as cultural identifiers, personal mementos, or simply beautiful artwork. Tattooing has a long history, practiced for centuries by many cultures around the world.
