We have different molecular weight Hyaluronic acid | |||
Type | Molecular weight | Effects | Application |
High Molecular weight | >1600kDa | Moisturizing and lubricating; good repairing effect | Recommend Molecular weight Tablet, capsules(800kDa-1200KDa) Solution, Sofegel(Less than 300kDa) Cream Eye cream(1000KDa-1300kDa) Facial cleanser, lotion,essence(800KDa-1000Kda) Mask(1300-1500KDa) Other Molecular weight can also be used, low molecular weight is more easily absorbed, high Molecular weight can lock the moisture easily, they can be combined and used together. |
Medium Molecular weight | 200 kDa~1600 kDa | Moisturizing,Diluting,releasing,stabilizing and emulsifying effect | |
Low Molecular weight | 10 kDa ~200 kDa | Nourishing the skin and Long-lasting moisturizing | |
Ultra-low Molecular weight | <10 kDa | Transdermal absorption, deep hydration, anti-aging, repair after sun exposure | |
