Body mods you regret?

I just did a face mask. And, because I had a nose piercing that I had to take out for work many year ago, I have a leeeetle hole packed with bright green mud mask. Every damn time.

When things are nice and clear (that is to say, free of green mud), I still have a hole that looks like a GIANT pore on the side of my nose.

Let's not get into the Biore nose strip discussion. Shudder.

Despite my (admittedly minor) regrets today, I'm still considering getting a tattoo. But I don't because I worry I'll hate it in 10 years.

So, how about y'all? Do you have a body mod you regret? Do you know someone who does? Are you happy with all of them?
