AI Technical Summary

⚠Technical Problem

Conventional cosmetic formulations with high molecular weight hyaluronic acid face issues of high viscosity, leading to stickiness and poor skin penetration, limiting its effectiveness and user experience, despite the need for higher concentrations to achieve optimal moisturizing effects.

⚗Method used

A method involving the application of shear stress to high molecular weight hyaluronic acid to form a single polymer chain structure with ionic aggregates, reducing viscosity without altering molecular weight, thereby enhancing skin permeability and moisturizing properties.

🎯Benefits of technology

The resulting structure maintains high molecular weight hyaluronic acid's benefits while significantly reducing viscosity, improving skin applicability and penetration, and enhancing moisturizing effects.
