Facial serum with moisturising and collagen-protecting active ingredients. This lightweight, water-based serum is specially formulated to delay the appearance of the first signs of ageing. Its comfortable, enveloping texture absorbs quickly, making the serum easy to use before a day or night cream. The serum contains medium- and low-molecular-weight hyaluronic acid, which provides optimal hydration to the different layers of the skin. Exosome-like vesicles derived from blue microalgae help protect collagen fibres due to their antioxidant properties.
