A few years ago I got a really great collagen facial in Las Vegas. The esthetian told me with confidence that when pimples show up on your face is a reflection of what is happening on the inside.
She explained that there were zones on the face, where pimples showed up, if there was an imbalance.
For example, if you get a pimple on your chin area it reflects an emotional strain. Perhaps you were going through a break up or another type of emotional worry?
