| Item | molecular weight | Function |
| Oligomeric (Cosmetics grade) | 5,000 Da | As below |
Conventional molecular weight (Food grade / Cosmetics grade) | 800~1,300 KDa | Soft and smooth without stickiness and rich in elasticity, long-term moisturizing, resistant to hyaluronidase degradation, can form a network of water film on the skin surface, lock water, isolate pollution, prevent ultraviolet rays. |
Low molecular weight (Cosmetics grade) | 100~ 800 KDa | Penetrate the cortex, hydrate and lock water for long-term moisturizing, and improve absorption of skin nutrition. |
High molecular weight (Cosmetics grade) | ≥1,800 KDa | Excellent lubrication and film formation, moisturizing, sun protection, thickening and stabilizing emulsification. |
Oligomeric sodium hyaluronate
1.Higher absorption rate: Transdermal absorption rate of oligomer HA can reach nearly 70% by using skin model test.
2. Repair damaged cells: Oligohyaluronic acid can repair damaged cells and improve cell activity, thus reducing the damage of external environment to skin cells.
3. Strong moisturizing properties: Ultra-low molecular HA can be combined with skin cells on the skin surface, which is not easy to wash away, and forms a strong moisturizing support and protection for the skin.
4. Deep moisturizing: It can be absorbed through the skin, deeply moisturizing and increasing the skin moisture content 6-7 times more than ordinary molecular HA moisturizing.
(Effects of different molecular weight sodium hyaluronate on skin)
Health food sector:
Skin hydration and anti-aging: It is often used in combination with vitamin C, collagen peptide, elastin peptide, grape seed anthocyanin, etc., to enhance the moisturizing and antioxidant effects.
Joint health, inflammation relief: Chondroitin sulfate and HA work together to protect joints and relieve osteoarthritis. Combined with glucosamine, it promotes cartilage repair and reduces joint wear. Curcumin + black pepper extract is highly anti-inflammatory.
Ocular mucosa repair: together with lutein and zeaxanthin to protect the retina and relieve dry eyes.
