Polymethylsilsesquioxane/Silica Crosspolymer
What Polymethylsilsesquioxane/Silica Crosspolymer 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/Silica Crosspolymer do in skincare?
This is a silicone-and-silica based powder-like ingredient used mainly to refine texture. It can give a smooth, soft-focus feel, help absorb excess oil, and reduce shine. In sunscreens it can contribute to a lighter, more elegant finish.
Is Polymethylsilsesquioxane/Silica Crosspolymer comedogenic?
Published comedogenicity data for this specific crosspolymer is limited, so a firm rating cannot be given. Silica and silicone powders typically remain on the skin surface, but how a full product behaves on acne-prone skin can vary. A patch test is a reasonable precaution.
Is Polymethylsilsesquioxane/Silica Crosspolymer natural or synthetic?
It is synthetic. The ingredient combines a silicone resin (polymethylsilsesquioxane) with silica in a crosslinked structure, produced through manufacturing rather than sourced directly from nature.
