Even Cleopatra knew the benefits and effectiveness of gold. Colloidal Gold can speed up the healing process of the skin by supplying the cells with nutrients and oxygen. Gold helps stimulate cell renewal and helps slow down all common signs of aging. It helps sun damaged skin and boosts collagen production. This makes it a popular luxury ingredient for facial serums and face creams, although it is usually a little more expensive, most people feel that the benefits justify the extra cost.
