Lithothamnium Calcarum Powder
What is Lithothamnium Calcarum Powder?
Lithothamnium Calcarum Powder comes from the fossilized remains of Lithothamnium calcarum, a red algae species from the Corallinaceae family found in cold, clean Atlantic ocean floors. This marine organism builds calcium carbonate shells, resulting in a fine, mineral-dense powder composed mainly of carbonates of calcium and magnesium, along with trace minerals. In cosmetic formulations, it serves in exfoliating products like facial scrubs, body polishes, and cleansing masks. Its mechanism involves the irregular yet rounded micro-particles (often 200-600 microns) that deliver controlled mechanical friction during application, buffing away surface impurities and dead cells while promoting even texture. The powder also enhances product rheology, providing a smooth, non-gritty feel that rinses cleanly.
