Magnesium Oil from the Zechstein Sea in the Netherlands offers highly concentrated pure magnesium chloride that is non-greasy and it is readily absorbed. Formulated with Menthol, Arnica Montana Extract, Peppermint Oil and Eucalyptus Oil to help you calm as well as moisturize the skin. It may be used regular and leaves no annoying odor. DIRECTIONS: Apply 4-5 sprays onto skin as well as rub the spot. After years you might see minimal white residue forming on skin in which you have applied the squirt. It is simply the salt that has stayed behind on skin and also can be wiped or washed off.
