Bald patch under female Syrian hamster chin

[MegOcean]

Hi, I was wondering if I could get some advice on a small bald patch which has occured under my 5 month ish old Syrian hamsters chin (please see photo).
It doesn't appear to be red or sore or like an open wound, but I just wondered if it is common/if it should require a vet visit?
She's perfectly happy behaving normally etc, I just wonder if there is anything I can do about it?
Would appreciate any help/guidance.

Thanks alot

Hello and welcome

I don't think it is anything to worry about. It may be a bit worn from poking her nose through the bars

Just keep an eye on it if it gets any bigger or watch if that area rubs against the bars
