As harmless as a body piercing may seem in comparison to something more permanent like a tattoo, it's important to note the possible health risks and complications that may arise when piercing a part of your body. You are piercing a foreign object through your skin after all. You'll need to ensure you understand what may happen and what to do if it does.
The time it takes for a body piercing to heal will depend on factors such as the type of piercing and where it's located on your body. Everyone is different so the healing time will vary from person to person. Another factor to take into account is if you've removed a body piercing and how long you've had it for, this will also determine the time it takes to close completely.
