Science
Mechanism of Action
DIPHENYL DIMETHICONE/VINYL DIPHENYL DIMETHICONE/SILSESQUIOXANE CROSSPOLYMER functions by forming a non-occlusive, protective film on the skin's surface, which minimizes transepidermal water loss and offers a barrier against external aggressors. Its unique structure enables it to absorb excess oil and sebum, contributing to a matte finish, while also scattering light to create a soft-focus visual effect that minimizes the appearance of imperfections. Furthermore, it enhances product texture by acting as a bulking and viscosity-controlling agent, improving spreadability and feel.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined this ingredient to be safe for use in cosmetics. Dermal irritation studies at a 100% concentration showed it to be non-irritating, and bacterial tests confirmed it is not mutagenic. While approved for general cosmetic use in Europe and regulated by the FDA in the US, the Environmental Working Group (EWG) notes potential for contamination by toxic impurities, recommending usage restrictions and warnings based on specific company data, despite allowing products containing it to be EWG VERIFIED™.
