What it is
This ingredient is a silicone elastomer in which cetearyl dimethicone and vinyl dimethicone units are crosslinked into a swellable network. In formulas it absorbs oils and helps build a thick, cushiony texture while delivering a dry, velvety, soft-focus finish that blurs the look of fine lines and pores. It is common in primers, sticks, and sunscreen or lip products where a smooth, mattified application is desired.
Safety & warnings
Silicone elastomers of this type are generally well tolerated, non-comedogenic in typical use, and have low sensitization potential.
Origin & sourcing
Synthetic; a crosslinked silicone (dimethicone) elastomer.
