The photoprotection chemists at Hallstar have long observed and learned from the plant world. While plants do not physically block UV rays themselves, they have needed to develop their own phytochemical defenses – carotenoids, flavonoids, polyphenols, vitamin C, vitamin E, a specific range of fatty acids, lipids, and more – to protect their cells from UV induced damage.

Hallstar was originally inspired to develop its revolutionary Micah^® chemistry (INCI: Bis(Cyano Butylacetate) Anthracenediylidene), for example, by noting how trees’ leaves avoid the photo-oxidation process that causes sunburn, despite spending months in direct sunlight. By focusing analysis on light-induced oxidative stress – specifically, how to stop the generation o ... ...
