Yes, bellafill can be used for chin augmentation and I often use it combined with sculptra. Radiesse is another great alternative and fat injections can be used as well. I suggest you see a cosmetic dermatologist or plastic surgeon with experience in facial contouring. Best, Dr. Emer.
Bellafill would be an excellent choice for chin augmentation as it stimulates collagen production and has an FDA approved 5 year indication.
