Recently I had a supplier who said that the Hydrolyzed Glycosaminoglycans enhance the skin penetration and helps the actives to act in a much better and efficient manner. When I did a little research all I could found was that it basically is a good skin moisturizing agent and to some extent helps the retention of the same for longer periods, relatively. Is it really a fact that it can enhance the skin penetration for the proper efficacy of actives??????
