I had it done last Christmas.
The actual process of getting it pierced didn’t hurt at all, I barely felt it.
They put in a very long bar at the beginning, so that your lip has room to swell.
I don’t know if this is typical, but the few weeks after getting it pierced, the skin around it was very, very dry and red.
It got better for a while; but then my skin grew over it and I had to get it cut out at the doctor’s.
Overall not a great experience, but I don’t think I took proper care of mine.
If you’re able to take perfect care of yours, go for it. 🙂
