Learning outcomes
Because of the frequency and after passing the final exam of the course “Skin photoprotection and cosmetics photodegradation”, the student -has acquired knowledge on the main photochemical and photophysical processes; o has acquired knowledge on the skin and the cosmetics oxidative processes under solar radiation, the main skin protection strategies and the experimental techniques used to assess sunscreen effectiveness; -can assess and select the best approaches for the photoprotection of the skin and the development of photoresistant cosmetics; -can apply the gained knowledge to real problems as well as to new issues related to skin photoprotection and cosmetics photodegradation.
