Lip piercing - new job in care home

[TrueFriendsStabYouInTheFront]

So I had an interview for a Carer job in a lovely care home and got the job, really pleased! Won't start for a few weeks due to crb etc!

Anyway, I completely forgot until today, that my brother said he would buy me a voucher for a lip piercing I want done. He just rang me to say he's got the voucher and he will take me on Saturday to go get it done.

Not sure if that will be acceptable in a care home or not as I have never worked in one before. It's a weekend job, my current job in the week is office based and not at all bothered about piercings or tattoos

So wibu to get it?

I've worked in a variety of settings (including care homes) with service users with violent and challenging behaviour. I have a few facial piercings and never had an issue. Most managers are just glad of someone willing to do the job! And in terms of risk because of violence I've never had one grabbed/pulled - plenty of other injuries though!

I am a deputy manager in a nursing home, I have tattoos and have a facial piercing, it's not frowned upon these days to have these.
I spoke to a cqc inspector who loved my tattoos.
Dementia type nursing may pose a risk with pulling it out though.
