Turning perilla citriodora into cosmetics! Exploring the skin Physiological effects of essential oils derived from a plant endemic to Japan
Working toward community revitalization
In rural Tamba, Hyogo, local industries such as the forestry business are facing severe challenges due to a shortage of manpower caused by aging residents and the population decline. The stagnating forestry industry has led to inadequate maintenance of mountainous areas, resulting in greater flood risks. To help alleviate the situation and revitalize the community, Ms. Niki is working with a local laboratory (Okutamba Botanical Research Institute) to use plants endemic to Japan (perilla citriodora) and grow in the Tamba area in cosmetics applications.
Perilla citriodora
Verifying the functions of perilla citriodora
This research focuses on the antioxidant effects of perilla citriodora. Ms. Niki believes that this plant can be an effective measure against oxidative stress, one of the factors that causes skin aging. Research shows that in recent years, various air pollutants place oxidative stress on the skin. This is due to the increase of reactive oxygen species (ROS), a factor in aging, when air pollutants stick to the skin. She verified that applying essential oils refined from perilla citriodora to cultured epidermal cells exposed to an air pollutant model substance inhibited the increase of harmful ROS on the cells. Industrial use of perilla citriodora has remained stagnant. The ingredients are derived from plants, making them environmentally friendly. Going forward, Ms. Niki plans on further verifying the effects and safe use of perilla citriodora with the goal of developing cosmetics that incorporate this plant.
Helping drive advancements in the cosmetics industry
Although Japan is a major producer of cosmetics, there are few places for advanced cosmetology studies at the university level. Ms. Niki is engaged in cosmetic science research using her experience in dermatology and research on verifying the safety and effectiveness of ingredients for cosmetics companies. She says, “Even if a cosmetics company has a product research and development program, many have difficulty in thoroughly investigating the effects and mechanisms at the cellular level. At the university, we can shed light on these mechanisms, allowing us to research high added value for cosmetics. In the future, I’d like for us to serve as a sort of external research department that engages in joint research with companies and manufacturers.” Ms. Niki wants to push the entire cosmetics industry forward. She says “The level of cosmetics research in Japan is world class, and I want to help take it to the next level. My primary goal is that graduates of our school form a Mukogawa Women’s University network where they can make a difference.”
