Purist blends never contain essential oils. Perfect for children, babies, and those with skin issues like psoriasis, MCAS (mast cell), and eczema.
While our mag products don't contain any essential oils either, they are brined, and therefore if you apply them to broken or cracked skin, it will sting (just like if you were to go for a swim in the ocean).
So instead, apply to your armpits or behind your knees. Your body will absorb it and send it to where it needs to go— no need to put it directly on the rash. Listen to your body.
