Supporting the Verification of Cosmetic Safety and Efficacy
Would you like to offer consumers greater peace of mind and trust by objectively demonstrating the efficacy of cosmetics, quasi-drugs, and daily-use products through a variety of scientific tests? We introduce know-how and insights gained from our extensive experience in contract testing to help guide your product development toward success.
-
Cosmetics and Quasi-Drugs
To support product claims such as “wrinkle improvement” or “brightening effects,” evidence is essential.
By applying a range of proven testing methods, we can clearly demonstrate the effectiveness of your products—helping to increase consumer purchasing motivation and strengthen your brand’s competitive edge in the marketplace. -
Daily-Use Products
Providing clear, data-backed evidence of functional effects—such as sterilization, antibacterial action, and deodorization—is essential for earning consumer trust.
We support the development of daily-use products that offer not only safety but also proven efficacy.
