Tattoos are permanent designs made on the skin using ink. The process involves inserting ink into the dermis layer of the skin with a needle. People choose tattoos for various reasons, including self-expression, cultural significance, or to commemorate important events or people in their lives. Tattoos can come in many styles, such as traditional, tribal, or realistic, and can represent anything from symbols to intricate artwork. While tattoos have been practiced for thousands of years across different cultures, they have gained popularity in modern society, often seen as a form of personal art or fashion statement.
