Common in pressed and loose setting powders, mineral foundations, and shine-control primers to keep makeup looking fresh.

Comedogenic Rating

This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.

Safety

Is Lithothamnion Calcareum Powder a Good Ingredient?
