Hi Sondra, I kind of feel the same way. I have actually been reading through the entire book and checking out all the ingredients to avoid, and why... I started doing this after I used a foaming cleanser (for OS) and had a negative reaction to it, and then discovered in another section (DS) that foaming cleansers shouldn't be used if (I think this was it) you have a damaged skin barrier - I believe I am truly an OS but have some DS issues. There is a lot of information in the book, and I have found it a little difficult to remember it all

Anyway, I'm sure there are specific reasons for the varying lists, but I am - I guess - being a little paranoid too....
