Pierced body parts are those that have been intentionally punctured with a needle or other sharp object in order to insert jewelry or other decorative items. The two most common pierced body parts are the EAR and the LIP. The EAR is typically pierced with a stud or hoop, while the LIP is usually pierced with a barbell. Both of these piercings require special care and attention to ensure proper healing and to avoid infection.
