Does filler absorb into the bloodstream. Is it ever in the bloodstream?

When fillers are injected by a highly trained and experienced physician, the risk of injecting filler that would end up in your bloodstream would be incredibly remote.

Hello - when placed in the correct locations, filler typically does not enter the blood supply. It remains outside of it, then is slowly reabsorbed by your body. There have been certain circumstances where filler was inadvertently injected into  blood vessels, which can result in catastrophic injuries to the face, eyes and brain. Therefore it is always best to be treated by an expert in facial anatomy, like a facial plastic surgeon.
