Expanding Treatment Options for Injectable Agents

Abstract

Loss of facial volume and soft-tissue support are common to types of facial aging. Restoration of a youthful appearance relies upon correction of this loss, and can be achieved in various capacities through use of biostimulatory or hyaluronic acids (HA) injectable fillers. Here, the authors discuss the versatility of calcium hydroxylapatite (CaHA) in volume replacement and the applications and facial regions for which CaHA, poly-L-lactic acid (PLLA), and HA fillers are best suited.
