A tattoo is a form of body modification made by inserting ink into the dermis layer of the skin to create a design, symbol, or artwork that is visible. Tattoos have become increasingly popular in recent years, with many people from all walks of life getting them to express themselves, mark a special occasion, or simply to make a fashion statement. Tattoos can be placed anywhere on the body, but one of the most popular and versatile spots is on the back.
