Silica Dimethyl Silylate is silicon dioxide whose surface is treated with silicone for water repellency. INCI: Silica Dimethyl Silylate. In a formula it works as a thickener, stabilizer, and mattifying agent: it raises the viscosity of the oil phase, keeps components suspended, absorbs excess sebum, and improves the sensorial feel. It is a functional component, not a skincare active. It often appears in sunscreens, primers, and long-wear cosmetics. Pregnancy safety. It is inert, does not penetrate skin, is systemically negligible, and there is no evidence of harm. It can be used during pregnancy and lactation. Tolerance. Irritation and allergen potential are low, suitable for sensitive skin.
