A low-viscosity cyclic silicone used in primers and lightweight cosmetics for smooth application. It is inert and well tolerated on the skin without identified safety concerns.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
