Other skin cream products may contain collagen, hyaluronic acid, or other skin nutrients that your skin can utilize to build younger and firmer skin. But your skin may have difficulty to absorb and utilize them. This is a common problem. But Astrion™ actually causes your skin cells (dermal and epidermal cells) to produce more collagen, hyaluronic acid, praline, and glucosamine by themselves. These materials are the building blocks of new skin cells. The end results are obvious and astonishing.
