  • Moduli: Francesca Soavi (Modulo 1) Marco Montalti (Modulo 2)
  • Teaching Mode: Traditional lectures (Modulo 1) Traditional lectures (Modulo 2)
  • Campus: Rimini
  • Corso: Second cycle degree programme (LM) in Advanced Cosmetic Sciences (cod. 9225)

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.
