The impact of daily stress on skin is the subject of our next webinar on Wednesday 28 May. This comes from Eri Kawashima of KOSÉ R&D, France, author of another Top 10 Poster from the 2024 IFSCC Congress.

Her study examined how psychological stress, a key component of the exposome, influences epidermal homeostasis. 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, 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.

BIOGRAPHY
Eri Kawashima is a research scientist specializing in cutaneous research at KOSÉ Corporation, a leading cosmetics company in Japan. After obtaining a master’s degree in biology, she joined KOSÉ in 2019 and has since been actively engaged in basic dermatological research, focusing on the biological mechanisms underlying skin appearance, as well as evaluating active ingredients based on these findings. In 2023, she was assigned to KOSÉ R&D France, based in Lyon, where she continues to conduct innovative research in the field of dermatology. The following year, at the IFSCC Congress held in Iguazu, Brazil, she presented her study on the effects of epinephrine, a stress hormone, on the skin. Her research was selected as a Top 10 Poster Finalist in recognition of her significant contributions to the field.
