Some weeks later.... The Sea Salt routine is easy and pretty neat, especially easy in carry-on for a flight! Anyway, it does IMMEDIATELY make the SD patches look better. If I let the salty water dry a bit then rub it around, it exfoliates.
I still get peeling patches so it may not be a cure yet but it is not as severe and not as frequent. I only worry about the long-term effect on the rest of my skin, not using any moisturizers, am I pickling my skin, turning it into leather?
