KOSÉ Wins Double Best Paper Award at SCCJ and ACST Cosmetic Journals

Overview KOSÉ Corporation has been honored with the 2025 Best Paper Award in both 'SCCJ' and 'ACST' (Applied Cosmetic Science and Technology) journals, published by the Society of Cosmetic Chemists of Japan (SCCJ). The research successfully identified distinct, non-obvious types of lip dryness and discovered three common light reflection patterns that improve interpersonal impressions across global skin tones.

SCCJ Journal Award ### Title Analysis of Lip Dryness Characteristics through Continuous Observation of Lip Surface Conditions

### Research Summary Beyond traditional dryness (State A, visible peeling), the study identified 'State B,' where dryness is felt but not visible. The study found differences in moisture content and evaporation rates between these states, suggesting the need for tailored products for those whose dryness is not addressed by standard treatments.

ACST Journal Award ### Title Discovery of Global Common Denominators of Skin Reflectance that Enhance Attractive Impressions

### Research Summary Researchers analyzed skin spectral reflectance data from diverse participants. They identified three light reflection patterns common to all skin colors that enhance attractiveness: (1) 'Purple or Blue' for elegance/clarity, (2) 'Orange or Red' for warmth, and (3) 'Both Blue and Red' for a lively/healthy impression. This achievement is applicable to base makeup products designed to fulfill specific desired interpersonal impressions.

Future Outlook This double award demonstrates KOSÉ's high level of research and technical standards in makeup. The company will continue to provide value based on scientific perspectives.
