Chicago has hard water, and I think it might have particularly high chlorine and calcium levels. (I say this having tried, poorly, to parse both the Chicago water quality report and the NYC report.) As I understand it, hard water doesn't completely rinse off soap etc. Combined with chemicals you've got dryness and residue. NYC has soft water and it rinses better. I grew up with hard water in Michigan and never had a problem; then I moved to NYC and after a few years I think my skin got used to soft water, and now there's no going back. (I have no idea if that's even possible or a thing, but just a theory.)
The only solution I've found online thus far is, if you're a renter, to install a shower head purifier (Sprite brand seems to make a good one, according to reviews). Next time I visit, I plan on making the bf install one right then and there. I didn't even wash my face with faucet water during my last trip -- I used bottled water like I'm a princess or something -- but I broke out just from taking two showers and having that water touch my face when I rinsed my hair.
If anyone knows a solution, please advise. This has long been a personal crusade of sorts.
ETA: But I also know that this one is 10x as expensive as the Neutrogena one, so there's that. There's an Olay one that someone has mentioned down thread, which I've not tried.
2. No, not everyone uses it every day. But I do.
3. I wash my face normally at night and use the Clarisonic in the am. Some people do vice-versa, I don't think it matters.
4. At the very least, remove your eye makeup before you use it. I like using it in the AM bc then I don't have any makeup on anyhow.
