The Swanson Mag oil came. In my opinion, the texture and feel of the oil feels very similar on the skin. The bottle has the official Zechstein Minerals BV seal, meaning that it does come from the Zechstein seabed. I think the stuff is the real deal.
Sadly, I'm not currently using it, as I have a nasty case of dry skin on the palms of my hands. I think it is from the mag oil. Has anyone else had this happen?
