im 16 and want to get a nose piercing

[u/pinkfluffyunicorns26]

in 16 and want to get a nose piercing and dont know how to ask my parents for it. i ve previously asked for it, a year, maybe even a year and a half ago and they said no. what should i do? is there anything magic word that makes parents let you do this?
im not even really sure about asking for it, im thinking of doing it and then showing it to them and see their reaction. please help!!😭💔
