If I’m honest, it’s better to go to an actual piercing place that use needles as they’re more sterile and safer.
I did get my ears pierced by Clair’s when I was 7 years old which was fine. Didn’t have any issues. But more recently I have been to a more professional place. They were helpful with the aftercare after my body had rejected my piercing and got it redone after leaving it for a few months.
Its done in the shop window where everyone walking past can see. And i may be wrong but isnt it just the shop assistant who does it?
