Description
Acts as a moisture-binding agent that helps draw water to the skin and maintain hydration levels in skincare formulations. Naturally occurs in human skin as part of the natural moisturizing factor, making it compatible with skin's own hydration mechanisms. While generally well-tolerated, some individuals may experience mild irritation with higher concentrations.
