Photoprotective complementary effects of sun filters and a combination of active molecules on UV-exposed human volunteers

In conclusion, our study performed in vitro as well as in vivo with non-invasive analysis of biomarker showed that this active association provides significant additional skin photoprotection to UV filters in terms of reduction of oxidative stress induced by UV rays. Sunscreens containing active ingredients, appear to provide better photoprotection at a cellular level than UV filters alone, and this ecobiological approach should be taken into consideration by dermatologists and users of such products.
