I learned last week of magnesium based pools, as an alternative for chloride or salt pools. It is said to be good for the skin.


There is also epsom salt; magnesium sulfate heptahydrate. You can add it to your bath. The science is unclear on whether the skin is actually able to absorb magnesium, but a lot of people swear by it.


My understanding is that the science is pretty clear that it's not able to.
