Can filler be reinjected in lips after biofilm infection?

Can you use Silk filler after an infection caused by filler?
After a year and a hyaluronidase injection, your filler should be all gone by now, though there isn't any way to prove that for sure. In theory, I think you could re-inject your lips with filler, but I think it will be tough to find an injector who wants to take the risk of this happening again to you! A good injector does not want to cause any harm, and it would feel risky to try this again. I would counsel a patient that it could certainly re-occur. If I had a patient who REALLY wanted to take this risk, I might try a thinner, shorter-duration filler like Belotero to see if somehow it was related to the filler brand/consistency. I would strongly discourage you from using Volbella or Voluma in your lips, because they are harder to dissolve with hyaluronidase than other HA fillers in the event of a complication.
Hypersensitivity reaction to dermal fillers
It's hard to know if the swelling was an infection or a hypersensitivity reaction. Hypersensitivity reactions are more common than infections, and can be triggered by the body's immune response to infections elsewhere in the body. The first two event treatments included steroids, which would resolve a hypersensitivity reaction. You don't mention a steroid at the third event, but some antibiotics (like doxycycline) have anti-inflammatory properties. I wouldn't go back with the same product, but wouldn't hesitate to try another family of HA fillers if your lips bother you. If you do, I would recommend an experienced aesthetic dermatologist, and be sure to discuss your prior experience.
