Body piercing, a form of body modification, involves puncturing or cutting a part of the human body to create an opening for jewelry or implants. The term "piercing" can refer to the act itself, the resulting opening, or the decorative jewelry used. Piercing implants, such as subdermal golden threads or metal implants, alter the body's profile and appearance. While the history of body piercing is often obscured by misinformation, ample evidence suggests it has been practiced worldwide since ancient times. Body piercing is performed on individuals of all ages, although minors are typically restricted to earlobe piercings.
