INCI: Polysilicone-11
Polysilicone-11 is a synthetic silicone elastomer — a rubber-like material that combines viscosity and elasticity. It forms a flexible, breathable film on the skin that delivers a smooth, non-tacky, non-oily feel. It is frequently used alongside dimethicone as a skin-conditioning and texture-enhancing ingredient.

Does Polysilicone-11 increase sun sensitivity?
No RiskPolysilicone-11 does not increase photosensitivity. No special sun protection measures are required when using products containing this ingredient.
Is Polysilicone-11 safe during pregnancy?
SafeTopically applied silicone polymers have negligible dermal absorption and are not associated with reproductive or developmental toxicity. No concerns identified in available safety literature.
