I understand your frustration. I found quite a few of the recommendations, for my skintype,to be totally wrong for me. I think you were given good advice to start back with a gentle cleanser and add a product at a time and see what bothers your skin. After trying the rec's for my skintype,I basically have gone back to my previous routine,adding only a RX retin-a..fortunately,I kept all my receipts and got a refund.I am glad I read the book and it did have lots of good information,but I was disappointed in some of the products,as they contained irritating ingredients and some did not provide adequate sun protection.I am old school I guess,but I think the fewer the products,the better.
