I came across this book while reading about it on an acne forum. I had mostly clear skin as a teenager, until around late 2009 (when I was 23 y/o) when my skin started to break out (face, back, etc).
It got to a pretty bad point this year in mid-2011. I recently cut out sugar from my diet (no cookies/smoothies/etc for 3 weeks and counting), the same time I started reading SKIN DEEP.
I don't know whether it was diet or lifestyle factors in my case (probably a combination of both--I have had a tendency to "over-worry" about certain things), but I recently saw a book on sale written by a couple of dermatologists who'd worked and researched for companies like L'Oreal, etc. I can't remember the title of that book, but the recommendations in that book read like a catalog for the acne-treatment/age-defying/blah-blah-blah products that the dermatologists were or had been associated with. I couldn't put much faith in it, especially since I HAD been trying out such products over a number of years, usually with little to no effect. In fact, the problem(s) usually got worse (I just used a gentle facial cleanser and some spot-treatment product occasionally, as a teen).
In comparison, SKIN DEEP cuts all that kind of fluff and immediately gets straight to the point about the skin being a reflection of one's emotional/internal state.
I'm about 3 chapters into the book, but already have gained a deep understanding of the perspectives that guide Dr. Grossbart's work and practice. Ironically, the negative review (here on Amazon, at the time of this posting), precisely shows the type of aggressive/angry individual that has unresolved issues (which could very well be turning up externally on the skin / as Grossbart states in his book, "What is your skin trying to tell you?" -- a simple question that's much easier to ask than answer).
I've been keeping a (part-time) skin journal, eating more vegetables (been experiencing withdrawal symptoms from lack of cookies/chocolate/sugar high), and my acne and eczema have gone down. I think (in my case) a lot of it had to do with not properly dealing with anger issues.
I hope I will "break out" less often (with the aim/dream of having clear skin again one day), and am doing my best this time to find the root issues/causes and work through/resolve them. I write for a living; my creative work has slowed down in the meantime (I used to rely on the "sugar high" for sustenance), but I think I have to put my health first this time.
I thank Dr. Grossbart for all the fantastic work he's done and continues to do for people with aggravating skin problems!
