Technical Features:

1) The enzymatic hydrolysis process with mild reaction conditions and green environment protection is adopted. Compared with chemical and physical methods, the molecular structure of the product is complete, the active functional groups are well protected, and the activity of oligomeric HA is maintained.

2) The enzyme used to produce this product is derived from invertebrate (leech). Compared with enzymes from other sources, it has high specificity and does not produce inactive monosaccharide and low activity odd sugar molecules.

3) The product has good biocompatibility and effectively penetrates into the dermal layer of the skin to play its role; it plays a real moisturizing role.

4) Hyaluronidase is expressed by yeast and does not produce endotoxin.
