Sansho Pharmaceutical is challenging a new stage.
In Showa 35 (1960) Sansho Pharmaceutical was founded with the corporate philosophy: “We contribute to society by satisfying the fundamental human need to stay young and beautiful forever”.
Since then, for more than 130 years counting from the establishment of the former Jinnai Sansho-do Pharmacy, we have continued to develop beauty ingredients with high efficacy and reliable safety in order to respond to aging concerns.
Underlying all research and development is the concept of "better ingredients, better cosmetics".
We are to develop beauty ingredients and cosmetics that exceed customer expectations and are more effective and safer. With this in mind, and without changing the "pharmaceutical method" that prioritizes the development of highly effective beauty ingredients, we have developed more than 130 beauty ingredients, including Kojic Acid, which created a concept of “brightening” for the first time in Japan, CTP, a hair-restoring ingredient, and Serumvital, an anti-wrinkle ingredient. And we have developed cosmetic products containing them.
Based on the concept of "better ingredients, better cosmetics", we intend to evolve to a new stage leveraging our strengths in ingredients, compounding, and formulation capabilities.
We will take on the challenges of manufacturing from the perspective of ecological, ethical, sustainability, and diversity. Furthermore, we will provide all services related to cosmetics manufacturing, such as contract development of beauty ingredients and various tests on safety, stability, and efficacy.
We will continue to respond to aging concerns and strive to be a company that can respond to desire to "stay young and beautiful forever" from every angle.
