We have been engaged in research on food products that can achieVe beauty from within the body. In the course of this research, we wondered if it would be possible to raise the effectiveness of application formulations (e.g., cosmetics) by enhancing the body's own antioxidant power, so we focused on glutathione, the endogenous antioxidant. After screening food materials that produce glutathione, we found Moringa oleifera, which not only promoted the production of glutathione but also inhibited melanin production In human studies, it was also found that the antioxidant capacity of the body was increased, and skin brightness was also improved through functional food ingestion. Therefore, we conducted a combination of studies of functional foods and application formulation and verified that functional foods enhance the effectiveness of application formulation.
