It is true that most soaps and body products have many added chemicals, some are hormone-disrupters that have some health risk. This is true whether they are bars or liquids. The ones with the moisturizing beads are the worst, and they are also extremely toxic to tiny life in the ocean because the itty bitty plastic particles are small enough to pass through cleaning filters.
Organic, all-natural or craftsman-made/home-made are probably the safest choices, but it will probably not give you the best skin.
I personally eat very healthy, natural food, get good exercise and avoid smoke, but I bathe in chemicals and slather them on my face...so I hope that it balances out!
I also use the neutrogena rain bath! I actually hate it (to me it smells incredibly strong, especially the "yellow" flavor). My husband refuses to check our closets before he buys more of things that he likes, therefore we always have 8-10 rain bath containers (and 8-10 refills of peppercorns, 8-10 jars of hot sauce...) but somehow I always end up having to use "yellow"!
