GOLD ASPARTATE/GLUTAMATE.

This ingredient's action is derived from its constituent elements. Gold nanoparticles are understood to stimulate microcirculation, encourage cellular regeneration, and contribute to skin repair. They possess anti-inflammatory and antiseptic properties, enhance skin firmness and elasticity, and are believed to promote collagen synthesis, thereby delaying visible signs of aging and vitalizing skin metabolism. Aspartic acid, a crucial non-essential amino acid, serves as a foundational building block for collagen and elastin, aiding in skin hydration. Glutamic acid, also a non-essential amino acid, functions as a humectant, drawing moisture into the skin, and acts as a skin-conditioning agent. It influences skin barrier repair, with potential differences in effect between its L- and D-forms, and plays a role in signaling cutaneous barrier homeostasis and epidermal hyperplasia following barrier disruption.
