It appears that you have a great result from your Bellafill injection. It is a great filler and only rarely makes lumps that have to be dealt with. In the past 10 years that I have been using Bellafill, I have only had to inject a few patients. I tell every one that they may get temporary lumps that they can feel but as long as the lumps cannot be seen they do not have to be treated. These lumps are usually the same lumps that we used to see with the original collagen fillers we used in the early 2000's and they always went away on there own. There is no need to inject 5FU and or Kenalog (steroid) unless you have a problem that can be seenI hope that helps and that you like your results. If so, make sure to write a review here on RealSelf to help other patients understand the benefits of this product.
