Résumé : |
Through evolution, the human body has acquired both a central nervous system (brain) and a peripherai nervous system (nerves and sensors including skin) which enable it to react to its environment and to survive.
Indeed, the brain and the skin originate from the same embryoiogic tissue, the ectoderm that differentiates to form neurectoderm (the future brain) and the epidermis.
The skin and the brain are constantiy communicating to syn¬chronize external and internai "danger" signais by means of cytokines, chemokines, electric impulses, and hormones.
Just as meditation is now recognised as e sure-tire way to soothe stressed souls, scientists have found a way to capture the rejuvenating effects of mindfulness, and deliver that same relaxing and rejuvenating boost to tired, stressed skin. This is because many of the most significant skin complaints - such as aggravations and ageing — are caused by stress. |
