smooth and moist, and protect the skin from bacteria, dust, and ultraviolet ray. With low molecular HA penetrating into
corium, it will slightly enlarge blood capillaries, speed circulation of blood, improve inter-mediary metabolism and nourishment absorbing ability of skin, thus eliminating wrinkles, increasing skin's elasticity and
delaying its aging. HA as well can further hyperplasia of epidermis cell, clean oxygen free radical, prevent and rehabilitate
breach of skin.
