VICHY Mineral 89 Hyaluronic Acid Serum is a skincare product formulated with key active ingredients aimed at providing hydration and skin barrier reinforcement. The serum contains hyaluronic acid, a potent humectant that can hold up to 1000 times its weight in water, aiding in skin moisture retention and plumping effects. Hyaluronic acid is a glycosaminoglycan composed of repeating disaccharide units of N-acetylglucosamine and glucuronic acid. Its mechanisms of action involve attracting and binding water molecules, thus increasing skin hydration levels and improving skin elasticity. Additionally, hyaluronic acid has been shown to stimulate collagen synthesis, promoting skin firmness and reducing the appearance of fine lines and wrinkles. The VICHY Mineral 89 serum also contains Vichy Mineralizing Water, rich in 15 minerals and trace elements such as calcium, potassium, and magnesium. These minerals have been scientifically proven to strengthen the skin barrier, enhance skin resistance to external aggressors, and improve skin hydration. The formulation of the serum ensures optimal bioavailability of these minerals to the skin, maximizing their benefits. Furthermore, the pH of the VICHY Mineral 89 Hyaluronic Acid Serum is carefully balanced to maintain skin health and prevent irritation.
