Science
Mechanism of Action
Operating through a grinding and polishing effect, Silicon Carbide physically removes superficial dead skin cells and environmental impurities from the skin surface. This mechanical action aims to refine skin texture and promote a smoother, clearer complexion by facilitating the removal of surface debris.

Formulation
Stability
Silicon Carbide exhibits extreme stability and high resistance to a wide range of corrosive substances, including strong acids and alkalis, indicating robust stability across diverse pH conditions.
Safety
Safety Profile
Silicon Carbide has not been specifically reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel or the Scientific Committee on Consumer Safety (SCCS) for cosmetic use. The EWG Skin Deep database classifies it with 'MODERATE' concern for cancer (referencing ACGIH, IARC) and 'HIGH' concern for developmental and reproductive toxicity, alongside general use restrictions. It is notably deemed 'Unacceptable' for EWG VERIFIED products and has been banned or found unsafe for use in cosmetics by the EU Cosmetics Directive.
