I would like to be able to consider Bellafill, however, I have had the alpha gal allergy for 5 years now. Even though the skin allergy test for Bellafill came out negative, I am concerned about delayed allergic reaction down the road. I am wondering if injection of the bovine collagen used may trigger a reaction as would ingestion, or not since it is a completely different "delivery method." Any thoughts/insight would be greatly appreciated. Thanking you in advance for your time... Roxanne
