Epson’s salt, also called magnesium sulfate, gets its name from the English county of the same name. Magnesium, with a high concentration in its composition, has multiple beneficial applications for the skin. Adding Epson salt to water and letting it dissolve releases the sulfate and magnesium ions, allowing their properties to be quickly absorbed into the skin.
Epson’s salts are a 100% natural product.
