Definition
Oligomeric HA, also called hyaluronan oligosaccharide or hyaluronan-oligo, is a kind of small molecule hyaluronic acid with very low degree of polymerization and molecular weight of less than 10,000 Da, that is, less than 50 monosaccharides, or the degree of polymerization less than 25.

Our Advantages
Our Advantages
1.  Use a proprietary process so that monosaccharides in the structure of hyaluronic acid will not break down.
2.  Measure the molecular weight of HA-oligo accurately using SEC-MALLS (size exclusion chromatography coupled with
      multi-angle laser light scatting)

Characteristics
1.  Rapid penetration into skin

The penetration rate of HA-oligo is about 3 times that of low molecular weight of hyaluronic acid ( 0.01~0.5×106 Da)

2.  Maintain skin moisture to a deeper layer

        Hyaluronic acid oligosaccharide rapidly penetrates into corneum to maintain skin’s moisture in a deep layer.

3.  Increase hyaluronic acid content in skin
     Since it can penetrate into skin, it will raise HA content in skin, activate skin, anti-aging and comprehensive moisturing.
4.  Good tolerance to heat as compared to medium and high molecular weight of hyaluronic acid.
5.  Easily disperse and dissolve in water with low viscosity.

Use Level
0.05%-0.6% in cosmetics
