I had a filler in my nasolabial folds and marionette lines 3 days ago. Can it be dissolved? (Photo)

This is really independent as voluma and belotero prob has the least potential to swell but belotero is for superficial and voluma for deep.  you can do a conservative amount of any filler and then touch up a few weeks later , which is often what I do for my high profile clients so if there...

Fillers are volumizers, so by definition, their role is add volume to where ever they are injected so they can narrow or slim the face. From your pictures, your cheeks are absolutely perfect and I strongly suggest against any cosmetic alteration of your cheek volume.

You did not mention what type of filler you had injected.  Hyaluronic acid fillers such as Restylane or Juvederm do not last that long.  These HA fillers are the only ones which can be dissolved.  If you had a permanent filler, it will not dissolve.
