Place the magnesium chloride flakes in the glass measuring cup or bowl and pour the boiling water over them.
Stir well until completely dissolved, about 1 minute.
Let cool completely and store in a spray bottle.
Notes
I prefer to use magnesium oil after a shower and often add 10 drops of lavender essential oil for scent and relaxation. It’s a great way to get a little self-care in!
This can be stored at room temperature for several months.
