Hyaluronic acid is a carbohydrate that occurs naturally in various parts of human body. In the skin tissue it helps retain the skin's natural moisture,hence it is used in skin-care products as a good water-binding agent.
A polysaccharide contained in Tremella Mushroom has an excellent water holding capacity. It can hold water equivalent to nearly 500 times its weight,which is greater than hyaluronic acid.
When the polysaccharide from Tremella Mushroom was applied to skin topically for 4 weeks,the water holding capacity of the skin and horny layer was greatly improved.
The effect of oral administration of Tremella Mushroom to skin is yet to be studied. However,it has a long tradition of dietary use by the Chinese people for this purpose.
