A permanent pattern made on the skin is called a tattoo. Tattoos are created by inserting ink into the layers of skin to create a design or pattern. The process of creating a tattoo involves using a needle to puncture the skin and inject ink into the dermis layer of skin. Tattoos can be created in a wide range of styles, colors, and designs, and can represent a variety of meanings or symbolism. Many cultures have a history of tattooing, and tattoos have been used for various purposes such as identifying membership in a group, marking important life events, or simply for decoration. While tattoos are generally considered permanent, some people may choose to have them removed through laser treatment or other methods.
