Serum developed from low-molecular hyaluronic acid, ceramides and squalane closed in structures of liposomes similar to cell  membranes. It allows efficient penetration of the fragile skin around eyes. Liposomes decompose in the skin and gradually release hyaluronic acid, which expands and fills wrinkles in the skin. Ceramides and squalane efficiently complement insufficient  amount of lipids in the corneous layer of the epidermis.
