The ultimate hydrator! Our skin’s hyaluronic acid production declines as we age. Hyaluronic acid serum applied topically plays an important role in tissue hydration and cellular function while enabling the skin to retain more water than any other natural substance. Properly hydrated skin promotes a healthy glow and diminishes fine lines and wrinkles. When followed by Squalane Moisture Seal this duo makes the perfect moisturizer for your skin.
