Hydrated silica is a porous mineral form of silicon dioxide processed for cosmetic use. It absorbs excess oil, gives a soft-focus matte finish, boosts slip and thickness, and offers mild polishing to refine texture.

Our take
Is Hydrated Silica a Good Ingredient?
It's Good because this porous mineral effectively absorbs sebum and scatters light for a smoother, matte look, with strong performance, stability, and inertness, though it works as a texture agent rather than a treatment active, which is why it doesn't rate higher.

Common in mattifying primers, setting powders, and oil-control cleansers to keep makeup looking fresh. Also found in gentle exfoliating scrubs for a polished feel.
Before you use it
Safety
Generally well tolerated and non-reactive on skin. In scrub formats, excessive pressure can feel abrasive, and loose powders should not be inhaled. May cause minor dryness on very dry skin.
