A blended silicone system combining linear dimethicone with a crosslinked dimethicone polymer, used to impart a smooth, silky skin feel, blur the appearance of pores and fine lines, and provide a breathable occlusive film. Commonly functions as a skin-conditioning agent and texture enhancer in moisturizers, primers, and sunscreens.
| Reported effect | How often | Notes |
|---|---|---|
| Comedogenicity (clogged pores/acne) | Rare | Generally considered non-comedogenic; occlusive buildup may rarely contribute to breakouts in acne-prone individuals. |
| Mild skin irritation or redness | Very rare | Silicones are largely inert; irritation is uncommon and usually linked to other formula components. |
| Allergic contact dermatitis | Very rare | True sensitization to dimethicone is exceptionally uncommon. |
| Pilling or product buildup | Uncommon | A cosmetic nuisance rather than a medical side effect, occurring when layered with incompatible products. |
