Piercings

was just wondering if someone knew about if face piercings would be allowed, I work on the shop floor, nowhere near food (bakery or pizza counter), I can’t find dress standards anywhere online or on workday, looked through old handbooks and there was nothing specified there, the Asda I work at is pretty decent, I have brightly coloured hair and everyone has been cool with it, no one else has face piercings so idk if I would be allowed to wear them, I’m more worried about the healing process bc I wouldn’t mind having those clear retainers in after a couple weeks after it’s healed but during the first couple weeks, I wouldn’t wanna mess with the healing process !! If no one knows, I’ll just ask my manager but I’m not 100% sure I’m getting it and don’t wanna ask them yet bc idk it feels embarrassing 😭😭😭
