On page 40, Diane says to "Slough off dead skin cells with a solution made of sea salt and lemon," but she doesn't offer the proportions for each ingredient. This kind of problem is present throughout the book. It's great to read some of the techniques she offers, but it doesn't do a lot of good when she doesn't explain everything we need to know about their application. It would have been more helpful if the author had included an appendix of "recipes" for the solutions she offers.
