Did you know magnesium is best absorbed through your skin?  And, that the primary way many of our ancestors did this was by swimming in the ocean?  Magnesium is essential for our body's proper functioning.  This is a magnesium spray that smells like the sea.  So as you spray this delicious medicine on in order to feed your skin, you will bask in the aromas of the sea.
 
As magnesium is significantly helpful for sleep, I recommend you spray it on your feet just before bedtime.  You can spray it anywhere on your body except eyes, mouth, nose, ears, and other mucus membranes.  It is normal to feel an itchiness and/or tingling where it's applied.  This sensation will diminish with regular use as your skin get used to it.
