Sodium RNA Good Antioxidant Anti-Ageing Sodium RNA at a glance Derivative of ribonucleic acid, an acid present in all living cells Primarily used as a skin conditioning ingredient Could have antioxidant and soothing properties \Usually derived from yeast Sodium RNA description Sodium RNA is also known as sodium ribonucleic acid, ribonucleic acid sodium, and RNA sodium. Ribonucleic acid is an acid present in all living cells and helps the body with several processes, including protein synthesis. In cosmetics, sodium RNA is primarily used as a skin conditioning ingredient. There is limited study that also indicates it can exert antioxidant properties on skin and reduces signs of irritation. Most sodium RNA used in cosmetics is derived from yeast; it can also be made in a lab or derived from animals. Usage levels of sodium RNA in cosmetics have not been firmly established.
