Biocosmetic effect: The serum contains three types of hyaluronic acid, with different molecular weight: low, medium and high molecular weight. Low-molecular hyaluronic acid easily penetrates the inner layers of the epidermis, forms a hydrocomplex with water molecules, preventing dehydration and intercellular compression. Visco-molecular hyaluronic acid has a different function, namely, it creates a matrix on the surface of the skin, drawing moisture from the air, creating an instant lifting effect. The regular repetition of hydrophobic regions in hyaluronic acid macromolecules enables interaction with cell membranes and hydrophobic types of protein. This property is of great importance for ensuring cell motility. Hyaluronic acid is involved in the control of processes such as tissue regeneration and renewal. Indications (intended for): Intended for daily care for dry, dehydrated and aging skin. Contraindications: Individual intolerance to the components of the product. Side effects: None, because hyaluronic acid is a natural substance produced by human cells. This serum is recommended to be used at any age, without any health risk. % ingredients of organic origin 100% ingredients of natural origin certified by Ecocert Greenlife and Cosmebio according to the COSMOS ORGANIC standard
