"I Wanted to Create Something Impossible for Human Hands alone" – Decorté's Challenge: Taking on "Cosmetic Formula Calculation" Using Quantum Computers
*The text-to-speech feature is generated by AI, so there may be errors in the reading.
With a relentless pursuit of true luxury through advanced dermatological science and sensuous textures, Decorté has sparked a revolution in cosmetics development. For the first time in the world[1], a "quantum computer" was used to calculate product formulas for "pore care," a common skincare concern.
We interviewed researchers Kentaro Yoshikawa and Shun Obikane from KOSÉ Corporation to get a behind-the-scenes look at this innovation, which fuses science and human ingenuity.
PROFILE
Kentaro Yoshikawa
KOSÉ Laboratory, Makeup Product Research Lab

Since 2019, has focused on quantum computer-related research at the Advanced Research Lab. Received the Best Oral Presentation Award at the 2024 Annual Congress for SCCJ for research on applying solubility parameters to powder dispersion technology.
PROFILE
Shun Obikane
KOSÉ Laboratory, Advanced Research Laboratory
Joined in 2020, now working as a data scientist after leveraging experience in AI-based image analysis research as a student. Tackles beauty challenges with mathematical approaches, including developing cosmetics using computers like quantum computers and developing new aging indicators through image analysis.
10 Seconds to Calculate 100 Billion Patterns[2]! Quantum Computer Technology Turning the Cosmetics Development Field Upside Down
What exactly is the difference between quantum computers and conventional computers?
YoshikawaIn a nutshell, the "calculating process" is completely different.
Conventional computers, while there's some innovation, basically have to process each possible combination one by one. In the development of cosmetic formulations, "combinations of ingredients and quantities" are the challenge—even a slight increase in the number of ingredients makes the number of combinations explode. If you tried brute-forcing all possibilities, some problems would take years to solve.
