Polymethylsilsesquioxane/Trimethylsiloxysilicate
What Polymethylsilsesquioxane/Trimethylsiloxysilicate is & what it does
A spherical silicone powder that gives a soft-focus, blurring effect and a smooth, dry slip. It reduces shine and improves the feel of the formula.
What does Polymethylsilsesquioxane/Trimethylsiloxysilicate do in skincare?
This blend of two silicone materials is used to improve texture and wear. Polymethylsilsesquioxane is a powder-like silicone that adds a smooth, soft-focus feel, while trimethylsiloxysilicate is a film former that helps a product stay in place. Together they can give sunscreens a silky finish and better water and transfer resistance.
Is Polymethylsilsesquioxane/Trimethylsiloxysilicate comedogenic?
Specific comedogenicity data for this silicone blend is limited, so no firm rating can be given. Silicone film formers and powders generally sit on the skin surface, but breakout potential still depends on the complete product. Patch testing is sensible for acne-prone skin.
Is Polymethylsilsesquioxane/Trimethylsiloxysilicate natural or synthetic?
Both components are synthetic silicones made through industrial processing. This ingredient is a manufactured blend, not a botanical or naturally occurring material.
