About

Ground-up oyster shells used as a gentle physical exfoliant in scrubs and masks.

Oyster Shell Powder is obtained by drying and grinding oyster shells, primarily composed of calcium carbonate (CaCO₃). It functions as a mild abrasive in cosmetic formulations. The particle size and shape determine its exfoliating intensity. No GHS hazard classifications, no EU restrictions, and it is CosIng-listed with a well-understood composition.
