Stearyl DimethiconeBarrier
A wax-like silicone used to thicken oil phases and add a smooth, water-repellent finish.
What it does
Stearyl dimethicone is a silicone modified with a long fatty chain, which makes it wax-like rather than fluid. It thickens and structures the oil phase, conditions the skin surface, and adds a smooth, somewhat water-repellent finish to balms and color products. It is a texture-and-feel ingredient rather than a skin active.
