Naturally occurring deposits of kieserite are found in salt pans where sea water becomes concentrated after prolonged evaporation. Kieserite typically contains 15.0% magnesium (25% as magnesium oxide, 75% as magnesium sulphate), 20.0% sulphur (as sulphate), up to 2.5% chlorides, and 12% water. The Magnesium Sulphate can be isolated from the other contents using electrostatic separation methods. Alternatively, it can be made by reacting magnesium oxide with sulphuric acid.

Epsom salt has anti-inflammatory properties which make it s a very suitable alternative for after sun lotions. You can mix 2 tablespoons of Epsom salt with 1 cup of water into an empty spray bottle and apply it to the body parts that have been exposed too much to the sun.
