Tips on piercing your own lip?

You should not do it yourself because you are at higher risk for infection and you have no idea how to pierce it yourself. Not to mention you have none of the tools to do it properly and safely. Plus, if your mom said she did not want you to get it done then she is more than likely just going to make you take it right out as soon as she sees that you did it yourself. Just wait until you can legally sign to get it done by a professional.
