Potassium Aspartate is the potassium salt of aspartic acid, an amino acid derivative used in cosmetics primarily as a skin-conditioning and humectant ingredient. It helps support hydration and skin barrier function and is generally considered a supporting formulation ingredient rather than a therapeutic active.
