- Functions of Different Molecular Weight HA
- High molecular weight
(MW between 1.5m~2.2m Da) can be formed breathable film on the surface of the skin, help the skin to lock moisture, and to prevent the invasion of bacteria, dust and ultraviolet, so that to protect the skin from damage
- Middle Molecular weight
(MW between 1.0m~1.5m Da) can tighten the skin and keep skin moisturizing for long term. Good moisturizing & lubricity, slow release, stable emulsification.
- Low Molecular Weight
(MW between 3000~100,000 Da) can penetrate into the dermis quickly, dilated capillaries slightly, promote blood circulation and metabolism, and it has the function of eliminating wrinkles, increasing skin elasticity and preventing skin aging.

- Applications
- Usage
Sodium hyaluronate is a cosmetic ingredient for skin care products. It can be processed either warm (<60°C) or cold and is incorporated into the aqueous phase of a cosmetic formulation. Sodium hyaluronate can form complexes with cationic compounds and proteins which may give rise to precipitation. For skin care preparation, the addition of 0.1%-1.0% Sodium hyaluronate is recommended.
