The skin is the largest organ of the body and one of its most important jobs is to act as a barrier to the external environment - preventing damage and infection from things like UV radiation, bacteria and chemicals. So you may be wondering, if it’s the skin’s job to keep things out then how is topical magnesium absorbed? Whether taken in the form of a supplement or sprayed over the skin, magnesium’s absorption is significantly boosted by being attached to an ion molecule such as chloride.10
Magnesium in the form of magnesium chloride spray is better able to penetrate the skin’s barrier. Magnesium can then be transported across the dermal layer by chloride, with studies showing that the hair follicles and sweat glands are a great help at absorbing up the magnesium to be taken up by the body.10
