@Mauritio I don't have any skin conditions, but apparently it helps. My brother had acne for a long time and stopped 2 months or so after we installed, though he doesn't think those 2 things are related.
The guy who installed it is a Russian guy who told me he is a plumber who didn't believe any of it for years and ended up him having it installed in his home showed me his arms. They were clear of any hair. He told me he had eczema for years and nothing helped, now the only thing that remained is the lack of hair on the arms.
Myself? The water feels very clean, especially if you can tolerate it when its cold and didn't sit in the sun-heated water tank for 2-3 days. When the guy installed it, he prepared a glass from before the installation, and a glass from after. The difference was night and day, the glass from after tasted much better, more reminiscent of sea water or water from the dead sea, if you've visited it.
If you'll go to some of the european natural springs the water is very similar in feel on the skin, and probably taste.
I dunno why I said owned, it still at my house on my water gate valve.
Excuse my rambling, I caught a cold 🙂
