Hard to tell from the pic, are they just the scattered chips or are there some vertical wear lines there?
If it’s the latter then the fork probably had bushing wear from lack of servicing. Is oil getting past the seals?
You’ve got a few options, new uppers, try filling in the damaged area with a teeny amount of nail varnish or just service it more regularly and keep riding until it dies then replace the uppers.
If it’s just those chips and they aren’t causing oil to get past the seals then just stay on top of your servicing and don’t worry about it
