My very favorite skin antioxidant solution - Natural Pacific Origin serum - I barely can remember a product which moisturize better than this one, even the under eye area! You will completely forgot what is dry skin.
And the Graymelin hyaluronic serum contains 100% of the solution of hyaluronic acid and that is pretty goof one.
The other my favorite one is RAMOSU - Hyaluronic Acid Solution 100, which is not in that video, but really great , skin smoothing serum.
