Diospyros Kaki Calyx Extract

What is Diospyros Kaki Calyx Extract?

Diospyros Kaki Calyx Extract comes from the calyx, the protective green sepals atop the fruit of the Diospyros kaki tree, native to East Asia and widely cultivated for its astringent persimmons. This botanical extract is produced through solvent or water extraction, yielding a concentrate rich in polyphenols, flavonoids, and tannins. In skincare, it appears in moisturizers, serums, and creams, functioning primarily as an antioxidant to stabilize formulations against oxidative degradation of oils and actives, preventing rancidity and discoloration. As a humectant, it draws ambient moisture into the skin's outer layer, supporting hydration levels. Its skin conditioning properties help maintain suppleness by interacting with the skin's lipid barrier, promoting a smoother texture without greasiness. Commonly featured in natural or Asian-inspired product lines, it aligns with clean beauty trends due to its plant-derived nature and multifunctional profile.
