Arianna Cozzi Speaks at Rutgers University’s Center for Dermal Research
On February 13, 2017, our PhD student from Pavia University presented " Prevention of photo-induced damage: sunscreen efficacy and safety " at Rutgers – The State University of New Jersey, hosted by the Center for Dermal Research. Arianna’s talk focused on how skin is composed of two major layers: dermis and epidermis. The epidermis plays a key role as our first protective barrier from external stress. The superficial layer of the epidermis is the stratum corneum (SC). The skin barrier function is related to the unique lipid composition of the SC, and changes in it may result in significant modification to the actives penetration into the skin. The effects of UV exposure on isolated SC and the penetration of two UV filters (Avobenzone and Octocrilene) were investigated with FTIR Spectroscopy and ATR-FTIR spectroscopy imaging techniques.
