Will bumps I have from Bellafill injections go away after almost four years? (Photos)

Bellafill and Artefill are known to cause granulomas. Although used for soft tissue augmentation, they can, and are known to cause permanent nodules and swelling. This is not the case for everyone. 
My office specializes in the removal of Bellafill and Artefill injections, in addition to silicone biopolymers, from the face and body. Initially, treatments are non-surgical with corticosteroids and immune modulators. If unable to be corrected, we can also perform surgery in some cases. 
Lastly, our office is conducting ongoing studies of plasma-assisted corticosteroid application, which allows for diffusion of the treatment medication in superficial tissue without causing atrophy.

Thank you for your question.  It seems that the bumps on your face will not eventually dissolve.  I suggest scheduling a consultation with an experienced doctor in order to look further into the matter and provide the appropriate treatment.  All the best.
