Maris Aqua (sea water) is a naturally sourced seawater used in skincare to provide trace minerals such as magnesium, calcium, potassium and sodium, often included for hydration and as a mineral-enriched base ingredient. It is typically valued for its osmotic and conditioning properties rather than as a primary therapeutic active.
