Colloidal Gold

Colloidal gold refers to gold particles that have been nanosized so that they remain dispersed evenly throughout a solution. According to the Personal Care Products Council, colloidal gold functions as an antimicrobial/antifungal or skin-conditioning agent. Recent research has shown colloidal gold can also be bonded with key antioxidants such as ascorbic acid (vitamin C), where it helps prevent molecule degradation and releases them more effectively into skin. Colloidal gold has been used in the world of medicine, where there is a minor amount of research showing that it might have benefit because of assumed skin-soothing properties. Although colloidal gold has not been formally assessed by the Cosmetics Ingredient Review Expert Panel, initial research has not demonstrated safety concerns. Skin permeation studies have demonstrated that spherical gold particles are non-toxic to human skin cells. t’s important to note that colloidal gold and traditional gold serve different purposes in the realm of cosmetics.
