Alumina - or aluminium oxide - a natural and environmentally-safe compound extracted from a sedimentary rock called bauxite. Measuring as small as 8 microns, the crushed rock is refined into small, sphere-like beads.
Unlike plastic micro-beads which form oceanic waste and is consumed by animals, alumina is environmentally-safe and nontoxic. In addition, its refined texture minimises micro-tears on the skin and makes it a superior alternative to larger, damaging particles such as fruit pits and nut shells.
