The necessity of matching a systemic and a topic photoprotection has emerged only in the last years, to get a longer and complete covering against acute and chronic damages caused by sun radiations. It is well known that free radicals, of the reactive oxygen and nitrogen species, are the majority of the radiations reaching the earth and consequently the skin; in fact, they are one of the main causes of UVA ray damage, responsible for cell and cell biochemicals physiology damaging at different levels. Systemic photoprotection aims to supply, through diet, antioxidant substances useful to hinder oxidative stress, main source both of acute damage, such as sun burns, and chronic damages (i.e., photoaging, photo-carcinogenesis and photoimmunosuppression) due to UV rays. Here we report the results of a study on the efficacy of a dietary supplement on sun erythema prevention, evaluated through the calculation of an erythemogenic minimal dose before and after the administration of this complement for 21 consecutive days.
