Hyaluronic acid is nature's moisturiser. It exists in every living organism and is the most important filling substance of connective tissue together with water. The skin contains 50% of the body's total hyaluronic acid. The human body produces hyaluronic acid, however, the quantity decreases with age – leading to loss in moisture. The skin looses elasticity, can become sensitive and dry as well as form lines and wrinkles. Aging skin needs protection and new elasticity through fresh moisture supplies. REPAGEN^® SERUM supplies your skin with the most important regeneration nutrients and protects it against outer aging factors.
