| Hyaluronic Acid(HA,Hyaluronan) is a natural biotic component,
widely existing in skin and any other tissue. It has
outstanding moisture keeping ability, thus called Natural
Moisturing Factor (NMF) in the world. It is the best
component used in cosmetics for moisture keeping in the
nature. When HA applied to the skin, macromolecular Hyaluronic Acid(HA,Hyaluronan) can
form an air permeable thin layer and keep the skin 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. Hyaluronic Acid(HA,Hyaluronan) as well can further hyperplasia of epidermis cell,
clean oxygen free radical, prevent and rehabilitate breach
of skin. |
