Silicone Oil

Silicone in the form of purified, medical grade, polydimethylsiloxane oil is considered permanent filler. It is used for the correction of moderate- depth lines and depressions. Microdroplets of silicone oil are dispersed within the dermal tissues, and fibrosis around these droplets localizes the material and provides “bulk” [10].
