Chain lengths or molecular weight distribution is an important factor in the production of hyaluronic acid in cosmetic products. Hyaluronic acid consists of long chains of sugar molecules that are linked together. The size and number of these chains determine the effectiveness and texture of the hyaluronic acid in cosmetic products.
Depending on the manufacturing process, hyaluron chains can have different lengths. There is low-molecular hyaluronic acid with smaller chains and higher-molecular hyaluronic acid with longer chains . The molecular weight distribution is thus a kind of classification system for the different types of hyaluronic acid.
Low-molecular hyaluron can penetrate the skin better and bind moisture, while higher-molecular hyaluron forms a protective layer on the skin's surface and thus ensures long-lasting moisture supply .
A combination of both types of hyaluron in one product can achieve an optimal effect.
The choice of molecular weight distribution depends on the specific requirements of the product and the desired effect. Some products only use low molecular weight hyaluronic acid for deeper hydration, while others prefer higher molecular weight hyaluronic acid for a long-lasting effect.
Overall, molecular weight distribution is an important factor in the development of hyaluronic cosmetic products as it influences the product's potency and texture, and thus can help improve skin hydration and health.
For our products we use a combination of all types of hyaluronic acid.
