The Magnesium Chloride line of products contain magnesium chloride sourced from ocean water and can feel similar to seawater on the skin. If you have sensitive, irritated, or broken skin, you may notice slight tingling, depending on which product you use. Our full-strength product is Magnesium Chloride Liquid. You may wish to dilute it 1:1 with water or a skin-friendly oil. Magnesium Chloride Spray, Balm and Gel are diluted to 50% strength and are suitable for most skin types. Magnesium Chloride Balm is especially ideal for sensitive skin because it is a rich, oil-based cream. If you experience irritation using our transdermal magnesium chloride products, discontinue use.
