New insights into skin inflammation: Elucidating the effect of stress on skin inflammation

It is known that psychological stress causes various skin problems for busy modern people.

Previous research has also reported that stress weakens the skin’s barrier function and recovery ability, and it is known that a disruption in the skin barrier can cause a variety of symptoms such as dryness, rough skin, and itchiness.

Through the research of mind and skin, KOSÉ has ​​now discovered that adrenaline, which is secreted in response to psychological stress, induces skin inflammation and reduces the function of tight junctions in the epidermis, which are important for the skin barrier.

What is a tight junction...?

The granular layer of the epidermis has a strong skin barrier structure that seals the gaps between adjacent cells without any gaps. If epidermal cells are compared to tiles, tight junctions serve as adhesion like the joints that fill the space between tiles. If a strong tight junction barrier is formed, it can prevent foreign substances from entering from the outside and moisture from evaporating from inside the skin.

Adrenaline-induced increase in inflammatory factors and structural changes in tight junctions

Inflammation-inducing effect of adrenaline

In an epidermal model where adrenaline was added, the structure of tight junctions changed

When adrenaline was added to a 3D epidermal model that experimentally reproduced human epidermis, it was found that the addition of adrenaline made the image of tight junctions unclear and caused disruption in the adhesion between cells.

To achieve healthy skin, it is important to prevent UV rays, dryness, and also inflammation and decline in barrier function caused by psychological stress.
