Science
Mechanism of Action
As a humectant, Hydroxypropylgluconamide functions by attracting water molecules from the surrounding environment and the deeper layers of the epidermis to the skin's surface. This mechanism efficiently maintains and increases the skin's intrinsic water content, thereby promoting optimal hydration and improving skin suppleness and resilience.
