A piercer is a professional who specializes in body piercing, which involves creating holes in various parts of the body to insert jewelry. This practice can include piercings in the ears, nose, eyebrows, lips, and other areas. Piercers use sterilized tools and follow safety protocols to minimize the risk of infection and ensure a safe experience for clients. To become a piercer, individuals often undergo training and may apprentice under experienced professionals. They must understand anatomy, hygiene, and aftercare to provide proper guidance to clients. Many piercers also stay updated on trends in body jewelry and piercing techniques to meet customer preferences.
