Nanotech formula could be skin’s fountain of youth

All day long, our skin is assaulted by pollutants, UV rays, radiation and other stressors in the environment. When these substances filter into the body through our pores, they can create reactive oxygen species – otherwise known as free radicals.

Oxidative stress caused by excessive free radicals is responsible for a host of skin conditions, including inflammatory diseases, pigment disorders, wrinkles and some types of skin cancer. It can also damage internal organs and cells that produce essential lipids, proteins and DNA. An innovative nanotechnology devised in Israel boosts the body’s natural defense mechanisms against oxidative stress, helping to produce adequate antioxidant enzymes to maintain the skin’s proper balance, according to report in the journal Cosmetics by a PhD student from the Hebrew University of Jerusalem in collaboration with researchers at the Technion-Israel Institute of Technology in Haifa. “The approach of using the body’s own defense system is very effective. We showed that activation of the body’s defense system with the aid of a unique delivery system is feasible, and may leverage dermal cure,” said Hebrew University researcher Maya Ben-Yehuda Greenwald.
