Piercing is a body modification technique that involves creating a hole in the skin to insert jewelry. Common areas for piercing include the ears, nose, eyebrows, and tongue. The process typically requires a sterilized needle and professional equipment to ensure safety and minimize the risk of infection. After a piercing is done, it is important to follow proper aftercare to promote healing. This may include cleaning the area with saline solution and avoiding certain activities, like swimming, until the piercing is fully healed. Different types of jewelry, such as studs or hoops, can be used depending on the location and personal preference.
