How do I convince my mom to let me get my lip peirced?

Autumn • 17 years old and I have been in a relationship for almost 3 years 💜
I'm 16, will be 17 in November. I really want my lip peirced, but my mom won't let me get it done. She says it's gross and that's were all of the germs are. But she is letting me get my nose peirced.... Wouldn't that be where all of the germs are because of boogers and stuff? (don't mind that I said boogers, not really sure what else to call it...)
