Hyaluronic Acid Serum for Fine Lines and Wrinkles hydrates deeply, reducing fine lines & boosting skin’s glow. Fine lines and wrinkles oftentimes arise due to dehydration of the skin and loss of collagen. Hyaluronic acid is supposed to have anti-ageing properties since it can retain its weight in water—more than 1,000 grams for every gram of hyaluronic acid. Hyaluronic acid pushes the skin, making fine lines and wrinkles fade into oblivion.
