Maris Sal

Maris sal is sea salt derived from evaporated seawater. It contains sodium chloride along with trace minerals including magnesium, potassium, and calcium. In skincare, it functions primarily as a skin conditioning agent rather than as an exfoliant or cleanser.The mineral profile of sea salt means it can help support the skin's natural ionic balance and osmotic processes. When formulated at appropriate concentrations, it may assist in maintaining skin hydration and supporting the skin's natural barrier function.

Sea salt works through osmotic action — the concentration of dissolved minerals in the salt solution can influence how water moves in and out of skin cells. This process, when carefully balanced in formulation, can support skin hydration rather than strip it.The trace minerals present in maris sal may also have mild conditioning effects on the skin surface, helping to maintain skin suppleness and supporting the skin's natural protective mechanisms.

Sea salt is used in very small concentrations within formulated skincare products — typically below 1%. When maris sal appears in your skincare, it works as part of the overall formula rather than as a standalone treatment. Use these products as directed on the label, and monitor your skin's response over a few weeks.

Sea salt is generally well-tolerated by most skin types. Those with very sensitive skin or disrupted barriers may wish to patch test first, as salt at high concentrations can be irritating.
