The technology we have is "plant exosome extraction" technology, which is a key source technology that can separate and extract only exosome in the active ingredients naturally secreted from plant leaves. In many plants, exosomes extracted from the leaves of Ginseng tree, a natural native plant in Korea, have been found to have excellent brightening, antioxidant, anti-inflammatory, and anti-cancer functions, and cosmetics containing Ginseng tree leaf exosomes have also been developed for the first time in the world.
