Gold particles are highly inert, stable, biocompatible, and non-cytotoxic and hence do not cause skin irritation, redness, or inflammation. At that, gold dust also holds the potential to fight surface bacteria. Gold dust penetrates quickly into the deepest layers to repair, rejuvenate and retexture skin cells. The ions present in gold dust stimulate the blood flow, which augments the natural metabolism of cells and eliminates waste secretions from the skin. In addition, gold dust increases collagen production that keeps the skin texture firm, and reduces skin sagging.
