Polysilicone-11 is a silicone-based crosslinked polymer used in cosmetics to form a smooth, flexible film on the skin, providing mattifying, blurring, and texture-improving effects. It is commonly found in primers, foundations, and sunscreens as a formulation ingredient rather than a treatment active.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation or redness | Rare | Generally considered non-irritating; mild reactions are uncommon and usually formulation-dependent. |
| Contact allergy/sensitization | Very rare | Silicone polymers have very low sensitizing potential; allergic reactions are exceptionally uncommon. |
| Acne or clogged pores (perceived) | Rare | Often regarded as non-comedogenic, though some users with very oily or acne-prone skin report breakouts, likely related to overall formulation. |
