Lithothamnion Calcareum Extract
Lithothamnion Calcareum Extract · Lithothamnion Calcareum Powder
A calcified red-algae extract — supplies trace minerals (calcium, magnesium, and others) to the formula.
What it does
Lithothamnion calcareum is a slow-growing red coralline algae harvested as maerl. Its calcified skeleton is rich in calcium carbonate, magnesium, and trace minerals. In skincare the powdered or extracted form is included as a mineral source, contributing a slight chalky feel and trace-element content. It is a supporting ingredient, not a targeted active.
Also known as
red algae mineral extract, maerl extract
