【Patent Sebum Measurement】Measuring the amount of sebum on the skin by the refractive index of light.
A blue LED lights up from inside the measurement probe that is in contact with the skin, and it is emitted onto the skin through the glass window.
The amount of sebum on the skin is measured using the refractive index of light. A blue LED is illuminated from inside the measurement probe that is in contact with the skin, and it is projected onto the skin through a glass window. The light that is absorbed and refracted by the skin returns through the glass window to the receiving unit, and the amount of reflected light is calculated to measure the amount of sebum on the skin's surface. The products we handle are based on "technologies for accurate measurement," represented by systems such as the factory's "quality control inspection system." They can also be used for research and development, planning, and design of cosmetics, as well as for product testing and quality control. For example, ■ We can customize skin diagnostic devices. ■ We can develop measurement and analysis equipment for laboratories. ■ We can integrate skin measurement technology into applications or existing measurement devices. We can respond to such requests. *For more details, please download the PDF or contact us.

Company information
The parent company of Esquiu, the Japan System Research Institute, was founded in 1968 by Akira Matsushita, the biological father of President Yukio Matsushita and an emeritus professor at Kanagawa University, with the aim of "utilizing research results from universities in the business world." It was a pioneer of "university-originated ventures," which were rare at the time, and in 1982, it succeeded in developing a moisture meter, considered the first skin diagnostic device in Japan. Since then, it has sold over 10,000 skin diagnostic devices (beauty computers) in total. Additionally, the products of the Japan System Research Institute are based on "measurement technology" exemplified by the "quality control inspection systems" used in factories. While having the backing of accurate measurement technology, we propose solutions to realize the "sales activation" of clients selling beauty products and services, tailored to fit their budget.
