This is a common question that many patients have asked me.
Personally, I review my patients within 2 weeks and use the remaining filler within this time period for the same reason that Dr Edwin mentioned.
I usually try to complete the filler injection in a single session, especially for Non-hyaluronic acid fillers like Radiesse. I am more cautious when storing and using this type of fillers because Non-hyaluronic acid fillers cannot be readily dissolved using hyaluronidase in the event of suspected infection.
Hope that this helps!
