Japanese multinational personal care firm Shiseido Company has collaborated with the National Research and Development Agency and the Japan Aerospace Exploration Agency (JAXA) to research the effects of stress.

The research will help Shiseido develop beauty solutions designed to reduce the effects of stress on the skin and body.

“The research team observed a disruption in the circadian rhythm of the salivary stress hormone cortisol and an increased distortion of facial expression.”

Shiseido researcher Dr Junichi Hosoi has been involved in a study of the relationship between stress, the skin and the immune system.

The team conducted this research using a closed-chamber training facility at JAXA’s Tsukuba Space Centre. Shiseido participated in three of the total five isolation tests completed.

During the participant’s time in the isolation chamber, the research team observed a disruption in the circadian rhythm of the salivary stress hormone cortisol and an increased distortion of facial expression.

The research results also suggested that these distortions can be considered biomarkers.

Shiseido will use the test results in applications development such as the Smile App for stress analysis.

JAXA will use the results to draft a stress assessment method for astronauts aboard the International Space Station (ISS).
