procollagen is water binding and moisturizing. Procollagen is a triple helical molecule of collagen, and is fully soluble and membrane permeable. It is hygroscopic and, as such, is able to bind many times its weight in water. Procollagen is found naturally in the skin as a first stage in the production of collagen. With age, there is a decrease in the skin’s procollagen content that may have some correlation to the increased dryness and reduction in elasticity often associated with mature skin.
