Haruharu Wonder Black Rice 10 Hyaluronic Cream has 10 types of multi-molecular weight hyaluronic acid offers water-based hydration and helps the skin surface look plump, elastic, and uniform. Complex types of hyaluronic acid at different molecular weights to provide multiple hydrating benefits to the skin, creates a protective layer on the skin to prevent moisture loss and keep the surface layer of the skin moisturized. Intermediate molecular weight maintains the levels of natural hyaluronic acid in the skin, and provides hydration by locking in moisture. Lower molecular weight penetrates deeper into epidermis to revitalize the skin, reduce wrinkles, and give the skin a plump and glowing appearance.
