Abstract
Aim: An ideal injectable material would be biocompatible with long-lasting effects. The relative polymerization and chain length of the compound determines its viscosity, as measured by centistokes (cp). It is available in 350, 1000 and 5000 cp - the higher the number, the more viscous the oil. Most of the reports used 1000-cp silicone oil for filling purposes and due to high viscosity, only microdroplet injection technique is recommended to avoid complications. This is the first report of patient series using liquid silicone with a 350-cp viscosity The objective of this study was to explore the reliability and efficacy of low viscosity liquid silicone for lower face contour correction.

Age-specific changes in facial soft tissues and their effects on facial morphology has been clearly decribed elsewhere[1,2,3]
Restoration of soft tissue through augmentation, modify facial contours, correct tissue loss associated with normal aging
Liquid injectable silicone has been used for soft-tissue augmentation[4,5,6]
Summary
Age-specific changes in facial soft tissues and their effects on facial morphology has been clearly decribed elsewhere[1,2,3]. Liquid injectable silicone has been used for soft-tissue augmentation[4,5,6]. Modern highly purified silicone products are available in the current practice which allow safer applications. Purified liquid silicone is chemically pure, free of particulate matter, clear, colorless, odorless, tasteless, nonvolatile, viscosity-constant within the range of human body temperatures[8]. The higher the viscosity, the more slowly the polymer will flow and less soluble in some solvents[9]. Various silicone brands with different viscosities are available such as Biopolimero-350, Silikon-1000, AdatoSi 1-500, and Bioplastique.
