I love piercings but my parents don't?

It's not that I'm not allowed to get them and it hasn't stopped me from doing so in the past, I'm an adult and I make those decisions for myself. However, I can't say it doesn't influence those decisions, which I hate. I've been wanting to get my septum pierced for a while, and I know for a fact that's one of the piercings my parents hate the most, everytime they see someone with one they make jokes that can be especially insensitive at time so it's made me feel uncomfortable just going for it and not caring. On top of this the last time I got a piercing (an ashley piercing) which is like the centre of the bottom lip, I went with my boyfriend and friend and they including myself thought it looked really nice on me. I get home and my mum tells me how stupid it looks and how I would've looked better with it almost anywhere else, and then at dinner in front of my friend who decided to stay her and the rest of my family continued to patronise and make me feel incredibly shitty about it. I kept it for as long as I wanted and took it out in my own time because that's what I do, I get piercings and if after a while I'm over it I take it out no issues. The thing that gets me the most is when I took it out, no one even noticed it was gone until I blatantly pointed it out to which they then said 'you look better without it'. I just hate how they make such a big deal of something that clearly couldn't have impacted them that much if they didn't even notice to begin with. What do I do?
