NMF (Natural Moisturizing Factor) is another name for heparin sodium which has been verified to be usable for moisturizing cosmetics and, in fact, widely applied in Japan, Europe, etc.

After several years of research, our company could eventually extract heparin sodium, winning a patent for extracting heparin sodium (Patent No. 10-1447123).

This will provide your skin with nutrition, moisture, freshness and energy thanks particularly to a sheet paper attached strongly to your skin.

Sodium Heparin is called ‘Skin Barrier’ to describe its ‘power of impounding water’ or ‘power of converting outer stimulation’. If the barrier doesn’t work, skin will be dried out due to lack of moisture and easily affected by outer stimulants like, for instance, ultraviolet. It could also destroy the metabolic rhythm of skin causing troubles including dermatitis on it. NMF, a kind of heparin sodium, acts to improve such function as a barrier, restoring moisture in skin and helping you regain healthy skin by protecting the skin from outer stimulation.
