I had a product similar to bellafill about 15 years ago, and the volume is fine, but when I smile it looks very unnatural because the product was injected right under the skin. I'm in the process of having it removed, but want to have a replacement of volume that doesn't move and look huge and unnatural when smiling. Is it possible to have filler in the cheeks that doesn't move when animating the face, or will I need an implant?
