The more I learn, the more I feel like a hypochondriac, but my skin definitely worsened in both aging and acne- immensely- moving from a less-hard water location to hard water location.
I'm taking this one with a grain of metaphoric salt since it's promoting these two products

but there might be something to this...
The filters that remove chlorine dont necessarily remove chloramine.
Chloramine can be removed for drinking water purposes by a carbon block or activated carbon filter that can be installed on a kitchen faucet. Also, both chlorine and chloramine can be removed for bathing purposes by dissolving Vitamin C in the bath water. One 1000 mg Vitamin C tablet will neutralize chloramine in an average bathtub. (18)

Sought this out as I learned LA is gradually changing its water from chlorine to chloramine, chlorine + ammonia. http://la.curbed.com/archives/2014/04/los_angeles_is_slowly_switching_to_bettertasting_tap_water.php
**** Amazon sells a product called Vitabath: Effervescent Vitamin C for Dechlorination!
After a week of the Vitabath, I've noticed no dramatic change in the texture of my skin. If anything, it's too acidic. I could add baking powder, but I'm afraid of what that will do to my hair- the C was not kind to it. Perhaps I'll try a filter ball on the bathtub faucet the next time I go to NY.
Going to try weekly ACV baths instead.
