Besides skin brushing I also installed a chlorine filter behind the shower head awhile back. The difference this makes in the skin is astounding. As I understand it the body also will absorb quite a bit of chlorine thru the skin and sinuses during one's shower because it is in a volitile state from the heat of the water. The difference is especially noticable when I take a shower at the gym and my skin just "crawls" from the chlorine in the water.
I got mine (Culligan) at the hardware store and have seen several other brands at environmental stores and online. I would highly recomend one to anyone - best $25 I've spent in awhile. Yes they are a bit funny looking but who cares if it works.
