At Garden of Wisdom we have been suggesting to our customers for quite some time about the connection between skin issues and the mind. Emotional and mental stress sets off a cascade chemical reaction in the body that can and does effect the skin in deeply profound ways. We have seen our customers use the best routines possible with the best products and not have full success with their skin until they addressed the emotional/mental component of their situation. Diet plays a role, but for the purposes of this article we will focus on the emotional/mental component.
When we first started mentioning this to customers, there were not many studies done on this. (the last 5-10 years) we were going purely by our experiences/conversations with our customers. (We feel this is pretty powerful anecdotal evidence in itself.)
However, it came with great excitement that new evidence now suggests our mindset can indeed play a huge role in skin health. There is a new field of study that reflects this called Psychodermatology.
From an article on Web MD - "Psychodermatogy is a field that addresses the impact of an individual's emotion as it relates to the skin," says Karen Mallin, PsyD, an instructor in the departments of psychiatry & behavioral sciences and dermatology & cutaneous surgery of the University of Miami/Jackson Memorial Hospital in Miami."
What the experts and studies are finding that the mind has a direct connection to your skin via neurotransmitters and neuroimmunoendocrine circuitry.
People are realizing that the psychological aspect is something we should really be looking into ourselves.
