An industrial piercing is a type of body piercing that involves two holes in the upper ear, connected by a single piece of jewelry, typically a long barbell. This piercing usually goes through the helix and can vary in placement, creating a unique and stylish look. The procedure is performed using a sterilized needle, and proper aftercare is essential to prevent infection. Healing time can take several months, and individuals should avoid changing the jewelry too soon to ensure the holes remain open and healthy.
