You know what's really funny? I just begun reading "Jane Scrivner's Water Detox". This paragraph made me think of this thread:
"The skin mirrors what is going on internally, so if you hear "You look great", "You are glowing", or "You look pale", or "You don't look good", you can be pretty sure of your state of inner health. The face can tell a thousand things and the most important of these is how well you are. The Chinese will even use the face and skin to help diagnose ailments. Chinese face reading looks at lines and coloration, and there are certain areas that are said to directly reflect the activity of the digestive system and liver - notably, the chin. So if you have a spotty chin, let the detox begin!"
