About this ingredient
Silica Dimethyl Silylate is silicon dioxide whose surface is treated with silicone for water repellency. INCI: Silica Dimethyl Silylate.

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.
