It should come as no surprise that seawater naturally contains trace elements and minerals, but did you know that our blood plasma and seawater contain almost identical concentrations of these elements and minerals? The two are so similar that you could place white blood cells from a human body in sterile, diluted seawater and those white blood cells would continue their normal function. Seawater contains many minerals that our skin needs including magnesium, potassium, calcium, selenium, sodium, and sulfur. Maintaining proper mineral levels in the skin is important for cell function and healthy skin. In addition, products that contain seawater can help strengthen the skin barrier, stop skin dryness, and soothe the skin. Find seawater in Phytomer Souffle Marin Cleansing Foaming Cream.
