How can I remove the fake filler from my face after biorevitalization?

This is difficult to answer without an in-person evaluation and not knowing what filler you were injected with. It may need to be removed surgically.  If it is causing inflammation, antibiotics and steroid/5FU injections can be used to calm it down. I recommend getting a formal evaluation with a cosmetic dermatologist.

The only way to even begin to answer your question is to know exactly what was injected into your face. 

Thanks for the question and photos.
Firstly, I am very sorry that this has happened to you. 
Secondly, it is difficult to give advice without an inperson assessment and knowing what you were injected with.
If this is a HA type filler then I would start with hyaluronidase injections to try and dissolve any residual filler. If not, then steroid type injections (like diposman) and antibiotics would be the next thing to try. If all of these fail then you may need surgical  removal of the filler and any associated infection/granuloma etc.
I would suggest arranging to see a certified plasric surgeon for an inperson consultation.
Good luck!
