Radiesse®/Radiance® is a long-lasting (1.5 – 2 year) injectable filler made with calcium hydroxyapatite, a normal component of bone that stimulates new collagen growth. This is a biocompatible filler that does not require skin testing. Dr. Park and Dr. Rebowe prefer to use Radiesse® for deeper folds and troughs, such as the nasolabial folds, and also for injectable implants such as cheek and chin implants.
