Outline of award-winning presentation

Collagen plays a crucial role in maintaining skin elasticity and firmness. However, the quantity and quality of collagen decrease each year due to aging and photoaging caused by ultraviolet rays. Many studies on collagen have focused on fibroblasts, the main producers of collagen. However, the roles of other cells in the dermis and their interactions with fibroblasts remain poorly understood. Shiseido has been conducting research focused on immune cells, specifically macrophages. The present study revealed that M1/M2 macrophages influence collagen homeostasis—a series of processes including ”production,” ”maturation,” ”degradation,” and ”digestion”—and contribute to the regulation of collagen quantity and quality. Moreover, based on these findings, Shiseido has discovered a novel approach to maintain collagen homeostasis and healthy skin via agents that regulate the M1/M2 macrophage balance.

Comment on accepting the award

It is a great honor to be awarded the 1st Best Podium Presentation at the ASCS Conference in Manila and to have our achievement recognized at the international level for the research that I have carried out day by day with the members of my research team. In the future, we will continue to enhance Shiseido's long-term research on collagen and develop innovative solutions.
