A tattoo is a form of body modification where a permanent design is made on the body by inserting ink, dyes and pigments, either directly into the skin or into a shallow layer. It is most often used to represent a person’s personal identity, beliefs, interests and style of expression. Each tattoo has its own meaning which is highly subjective and individualized to the bearer. It may reflect an individual’s heritage, values and beliefs, celebrate an important event, or signify spiritual and religious devotion. Tattoos can also be used to convey a message or show support for a cause. They can serve as reminders of a moment or experience, serve as symbols of protection or strength, and can also signify emotional ties to another person or loved one.
