This Hyaluronic acid stock solution is an original formulation that took one and a half years from development. Conventional hyaluronic acid is mainly made by mixing a small amount with cosmetics to increase the viscosity, and when it is dissolved in water to the maximum as a stock solution, the viscosity is too high to use.

The undiluted solution has been improved so that it does not become sticky and has a smooth feel even when used as it is, while maintaining the high water retention capacity of hyaluronic acid.
