Query: Nothing I haven't heard/read before

I am extremely disappointed. I was expecting new, fresh, exotic ideas of skin care from around the world. Having read it cover to cover, I don't think I found one idea that I haven't heard/read before. Further, Shalini (the author) mentions her skin care line throughout the book, therefore, I can only surmise that the intention is to further publicize her online products. I'd like my money back!
