How can I maximize the benefit of Hylau B5?
For the deepest hydration, apply Hyaluronic Acid to damp sink to maximize absorption. We recommend that you mist your skin with our Thermal Spring water before use. Dont forget to lock in moisture with a moisturizer.
Why is Hyaluronic Acid effective for anti aging?
This skincare ingredient can hold up to 1000x its weight in water, which is important considering as we age our skin loses the ability to hold onto water and stay moisturized—causing visible loss of plumpness and suppleness in our skin’s appearance.
