Piercing needles are specialized tools used for creating holes in various materials, most commonly in the human body for body piercings. They are typically made of stainless steel to ensure durability and minimize the risk of infection. These needles come in various sizes and gauges, allowing for different types of piercings, such as ear, nose, or navel piercings. The process of using a piercing needle involves sterilization to prevent contamination. A professional piercer often uses a hollow needle, which removes a small core of tissue, making it easier to insert jewelry like earrings or nose rings. Proper technique and aftercare are essential for healing and preventing complications.
