Inquiry regarding additional filler treatment in other hospitals

I would like to inquire about filler treatment.

I have previously had filler treatment at another hospital, and it has been some time since the treatment was done in that area.
I would like to visit Maypure this time and receive additional filler treatment in that area.

Inquire about the possibility of additional treatment in the area where the hospital filler was administered

There is a possibility that there is residual filler left in the area scheduled for the procedure. I am wondering if the procedure is still possible in this case.

1. Can I proceed with additional filler treatment right away when there is residual filler?
2. Or, I am wondering if I need to undergo a removal procedure to dissolve the existing filler before I can get a new filler.
3. If the remaining filler needs to be removed first, please also let me know whether the removal and re-treatment can be done at the same time, or if there should be a certain interval between the treatments.

I would like to know in advance if it is possible to visit.
Have a nice holiday
