Alpha–Glucosyl-Rutin (AGR) is a natural ingredient extracted from the pagoda tree that is suitable for dermo cosmetic applications. This highly tolerable ingredient has very powerful antioxidative effects being able to prevent oxidative stress caused by sun induced free radicals – which are the most important triggers of sun allergy. It has been proven that anti-oxidants like AGR help to significantly reduce the risk of developing sun allergy symptoms, also known as Polimorphus Light Eruption (PLE), and Acne Aestivalis.
