Is Polymethylsilsesquioxane/ Silica Crosspolymer a Good Ingredient?

Good rating because the crosslinked silicone-silica network provides reliable blurring and oil absorption with stable, inert performance and a low irritation profile. It improves slip and soft-focus effects across product types.

Skin Benefits

Improves cushiony slip and minimizes the look of pores while keeping excess oil in check. Improves a smooth, filtered appearance without heaviness.

Uses in Skincare & Cosmetics

Included in shine-control primers, long-wear foundations, and BB/CC creams to refine texture. Also used in talc-free setting powders and blotting balms for lasting matte wear.

Safety

Typically low-irritation, though its oil-absorbing nature can feel drying on very dry or sensitive skin. If supplied as a loose powder, avoid inhaling dust during application. No common regulatory restrictions are noted.
