What it is
Polysilicone-13 is a silicone (siloxane-based) polymer used in skincare and sunscreens for its film-forming and conditioning properties. It helps the product spread evenly and dry down to a smooth, flexible film, and it contributes a silky, non-greasy skin feel typical of silicones. It is often included to improve the cosmetic elegance and wear of the finished product.
Safety & warnings
Silicone polymers of this type are large and largely inert on the skin surface and are generally well tolerated, with low expected irritation or sensitization potential. Polysilicone-13 is not a known fragrance allergen and, as a silicone rather than a fatty oil, is not associated with comedogenicity.
Origin & sourcing
Synthetic silicone polymer manufactured from siloxane chemistry.
Questions everyone asks
What does polysilicone-13 do?
It acts mainly as a film former and emollient, helping the product spread evenly, set into a smooth layer, and feel silky on the skin.
Is polysilicone-13 a silicone?
Yes. It is a siloxane-based silicone polymer, used for its film-forming and skin-feel benefits rather than for any active effect on the skin.
