A tattoo is a form of body art created by inserting ink into the skin's dermis layer. This process involves using a needle to puncture the skin, which leaves a permanent design. Tattoos can vary in size, color, and complexity, ranging from simple symbols to intricate images. People choose to get tattoos for various reasons, including personal expression, cultural significance, or memorializing an event or person. The practice of tattooing has a long history and can be found in many cultures around the world, often associated with traditions and rituals, such as those seen in Maori or Polynesian societies.
