About the Webinar

This study examined how psychological stress, a key component of the exposome,
influences epidermal homeostasis. Our in vivo experiments demonstrated that epinephrine, a key stress hormone, was significantly elevated in the epidermis of highly stressed individuals compared to those with lower stress levels. Furthermore, our in vitro and ex vivo studies revealed that epinephrine directly impairs the function of tight junction barrier, suggesting a novel mechanism by which psychological stress may compromise skin barrier integrity.
