A tattoo is a permanent form of body art created by inserting ink into the skin's dermis layer. This process involves using a needle to puncture the skin and deposit the ink, forming various designs, symbols, or words. Tattoos can be simple or intricate, ranging from small, discrete pieces to large, elaborate artworks covering extensive parts of the body. They often carry personal, cultural, or artistic significance, reflecting individual identity, beliefs, or memories. Tattoos have been used for self-expression, commemoration, and as part of cultural or religious traditions throughout history. Each tattoo is unique, embodying the personal story or artistic vision of the wearer.
