Bellafill and alpha-gal allergy: are there any contradictions?

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.

Since you had a negative Bellafill skin test, I would consider it safe for you to have Bellafill treatment.  I have not seen any delayed allergic reactions with Bellafill.
