I've been using Magnesium oil for about a month now. Over the past 2 weeks, the underside of my hands have become very dry with cracked skin. I'm going to stop using the Mag oil for a while and see if it clears up. Has anyone else experienced this with Magnesium oil? Other sites on my body where I have been applying the magnesium oil are not dry or cracked at all...only my hands are showing this.
