Industrial piercings should always be done by a licensed professional with proper anatomical, procedural, and technical knowledge in a sterilized area. Industrial piercings require two piercings to be made with a piercing needle since the piercings must be precisely aligned to be properly connected with a single piece of jewelry like the
barbell jewelry. Piercing guns should never be used for an industrial piercing because they are designed for lobe piercings, not cartilage ones. Additionally, piercing needles are designed for single-use, meaning they have less bacteria, thus decreasing risk for infection. The barbell jewelry worn with industrials are usually 14G, but may also be 16G. One of the piercings, the forward-helix piercing, is made closer to the head, while the second piercing, the outer-helix piercing, is made on the opposite side of the ear. While barbell jewelry is typically worn during the healing period to maintain piercing alignment, a pair of
captive bead rings may be used as an alternative. Using captive bead rings may result in faster recovery times at the risk of the piercings becoming misaligned. == Aftercare ==
