The design of the book pages is cute and pleasant. It's good that the book includes the Latin names for the ingredients. There are tons of recipes for every part of the body in a variety of applications. There are references, but they're mostly for other herbalism/beauty books and not scientific sources for the health claims. I would have liked more information about what the individual ingredients do so that I could make informed substitutions and customizations if I couldn't get a particular component, especially since many of them are not common. Many herbalism-related terms aren't explained. (Presumably the authors want to usher readers to their skin care course, though they say the book is supposed to stand on its own.) There are some warnings but they're not complete (e.g. no mention that St. John's Wort can cause photosensitivity, at least one zinc oxide powder recipe missing the warning about breathing it in).
