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. Natural vegetable oils: argan, jojoba, and safflower oil strongly moisturize and regenerate the skin. Cucumber seed oil provides an inflammatory and smoothing effect, while opuntia macerate revitalizes the skin, soothes irritations, and improves the structure of the hydrolipidic film. Serum features a fresh fragrance of cucumber.
