Science
Mechanism of Action
This copolymer operates by forming a continuous, molecularly thin film across the stratum corneum. This barrier strategically minimizes transepidermal water loss, effectively preserving skin hydration. Concurrently, it provides a protective shield against external aggressors such as environmental pollutants and UV exposure, while contributing a characteristic smoothness and slipperiness that conditions the skin.

Safety Profile
The CIR Expert Panel thoroughly reviewed Methicone polymers, including this ingredient, concluding them 'safe as used' in cosmetic products in 2020. This determination was based on their large molecular weights, rendering skin absorption unlikely, even with increased usage frequency. The FDA also acknowledges its good safety profile as a skin protector at low concentrations.
