Should I Dissolve Remaining Superficial Filler?

Hyaluronidase often needs to be repeated a week or so after the first time.  It is safe if injected properly and should break down the remaining product. Belotero doesn't last as long as Juvederm or Restylane but it can be a few months anyway You should massage gently or see your doctor for a Hyaluronidase touch up.

It not risky to dissolve the remaining Belotero filler as long as Hyaluronidase is injected properly. I prefer to wait for about 2 to 3 weeks after initial Hyaluronidase before injecting it again. If you are seeing improvement, maybe it's a good idea to observe it a bit longer before reinjecting it. 

Best wishes,

If you leave the remaining Belotero under your eyes, I doubt it would last for more than another six months, although sometimes it could last a bit longer in that area.  I do not think it is risky to have the remaining portion dissolved with hyaluronidase.  It's really a question of how much it bothers you.
