Science
Mechanism of Action
As a polysiloxane, Polysilicone-12 functions by depositing a continuous, flexible film across the skin's surface. This polymeric layer enhances the tactile experience, imparting a distinct slip and a smooth skin feel. Furthermore, the silicone elastomer particles embedded within this layer are capable of diffusing incident light, effectively obscuring shadows cast by fine wrinkles and thereby delivering a desirable soft-focus aesthetic.

Safety
Safety Profile
The Expert Panel for Cosmetic Ingredient Safety (CIR) has not specifically reviewed Polysilicone-12. However, related ingredients such as Polysilicone-11 were deemed safe for cosmetic use, with reported concentrations up to 19.9% in skincare. Polysilicone-15 was reviewed by the SCCNFP, concluding its safe use as a UV absorber at up to 10% concentration, and it is permitted as a UV absorber in US cosmetics, though its sunscreen use status is pending FDA review.
