Ultraviolet (UV) radiation from the sun drives accumulation of reactive oxygen species (ROS) and inflammation in the skin. UV radiation also depletes skin cells of antioxidant enzymes, including superoxide dismutase (SOD). Increased ROS and decreased scavenging enzymes contribute to photoaging of human skin through oxidative damage to proteins, lipids, and carbohydrates. The Garrett lab has discovered an innovative method to deliver antioxidant enzymes to sites of inflammation and oxidative stress using lactic acid bacteria as a carrier for SodA. Cosmetic products containing SodA producing lactic acid bacteria may repair UV damaged cells and protect healthy cells against future environmental damage and photoaging.
