Sea Water

Sea water is just what you’d think: water obtained from the sea or, more specifically, inland bodies of salt water. As with all types of water, this one has solvent properties but is also a humectant, in part due to its natural mineral and trace element content. Some of the numerous minerals in sea water, such as magnesium, can have soothing properties when applied to skin. Other minerals in sea water include sodium, zinc, potassium, calcium copper, and manganese, although the specific content varies based on where in the world the sea water was obtained as well as the depth of water. Research has shown the primary minerals in sea water, including salt and calcium, have a regulating effect on skin’s barrier. This makes sea water (especially when bathed in) beneficial for certain skin conditions involving barrier impairments. In dermatologist parlance, this is considered “adjunctive therapy”, meaning it complements medical treatments a doctor prescribes to help certain skin disorders improve. Sea water’s acidic nature coupled with its mineral content also seems to play a reparative role when applied to environmentally compromised skin; however, it hasn’t been shown to surpass what numerous antioxidants, including vitamins, can do in this regard. Sea water usage levels in cosmetics do not have a standard range. It can be used in any amount up to 100%, depending on the nature of the formula and desired results. Of course, it’s not exactly the same as taking fresh water from the sea since the sea water used in cosmetics is purified to remove undesirable content in the water.
