Face Mapping for Acne

When I did a google image search of face mapping, this advertisement came up for dermalogica. What I found really interesting about the advertisement was the language used in it. "With Dermalogica's unique Face Mapping zone-by-zone skin analysis, you can discover the real reason behind your skin concerns." (emphasis, mine) Similar to the language used in describing the face as the window into the soul and discovering the true person, apparently the face can also give information concerning acne and other body ailments. It also reminded me of the face maps that came up a lot in the film Chinese Box.
