The active ingredients are pure and concentrated: HYALURONIC ACID Binds water in the epidermis, drawing it in from the deeper layers, maintains the right level of moisture in the epidermis and physiologically slows down the evaporation of water. TREALOSIUM It is used for its protective capacity against macromolecular structures in the skin and for its membrane-stabilising power. Indeed, by virtue of its structure, it is able to trap proteins, nucleic acids and biological membranes by forming a thin film, protecting them from adverse situations such as cold, ionising radiation and dehydration. In the case of skin dryness, Trehalose is able to absorb moisture, ensuring prolonged hydration. TRIPEPTIDE 29 A naturally-derived peptide that reduces wrinkles, firms and stimulates collagen biosynthesis.

Apply small amounts to perfectly cleansed skin and spread gently.

ONE, a hyaluronic acid serum from the men's line, leaves the skin feeling turgid and radiant, thanks to its ability to draw in huge quantities of water from the deepest layers of the dermis. To the long-term moisturising action of hyaluronic acid is added the extraordinary synergy with the exclusive tensor-effect polypeptide, making it a powerful cosmeceutical of the latest generation.
