Concern level

Silica is silicon dioxide (SiO2), a mineral ingredient used in cosmetics mainly as an absorbent, anti-caking, bulking, slip-improving, and texture-enhancing powder. Cosmetic-grade silica is typically amorphous rather than crystalline. It is generally considered low-risk for topical use and is widely used in powders, foundations, primers, and skincare products to reduce shine and improve feel.

Interactions

incompatible with: No major topical ingredient interactions are known., Avoid excessive airborne dispersion in sprayable or loose-powder systems., Can contribute to dryness if paired with strongly drying formulas or frequent over-application.

Risks & Warnings

Generally low hazard in finished cosmetic use. Main concerns are eye irritation from loose powder and inhalation of fine airborne particles during manufacturing or spray/powder application. Crystalline silica is an occupational inhalation hazard, but cosmetic silica is typically amorphous. Can feel drying on very dry or compromised skin if used heavily.
