Raena Morgan: Have there been other studies as well? Dr. Holly Showalter: Sure, lutein has been studied in different research models where the scientists would look at high energy light and the high energy light will cause reactive oxygen species. And they have looked at luteins role in the diet of these research models and looking at its protective role and protecting from the reactive oxygen species leading to inflammation. So we believe again that the lutein in the diet is actually helping to protect the skin cells from the damaging effects from... Raena Morgan: Free radicals. Dr. Holly Showalter: ...Free radicals and ultraviolet light. Raena Morgan: Okay well, thank you Dr. Showalter.
