Restylane filler on my under eyes. Left over to be used in lips 7 weeks later. Is this safe? Is bacteria a risk? Should I?

I got tear trough fillers on 6/2. The injector told me she wasn’t going to use the full CC because she likes do fillers progressively. Told me to return in 2 weeks once any swelling reduced. I only used .45 of the 1 CC, about .55 still left. No available appointments. Now I’m not booked until 7/23. I’m being told I cant use it now on my under eye bc it’s a sensitive area yet they say it’s OK to use on my lips? Is it really safe to use what was left From 7/2 in my LIPS?
