Thank you for your informative and thoughtfull post. Sea Salt makes complete sense to me, though the thing that was a immediate halp for me is Bentonite Clay, which is mericale to bear sd. Just 30 minutes of the Bentonite mask gives me complete flake off my face. The skin becomes soft, no signs of sd, no redness, no itchiness. I do it every week now..My thumb is up for the Bentonite Clay.
