Topical application of an antioxidant mixture can complement sunscreen use in order to protect the skin from UV damage, according to a new study.
Researchers from L’Oreal USA, alongside independent scientists from Dallas, Texas, studied the protective effects of a mixture of vitamin C, ferulic acid and phloretin. After applying the mix to the skin of ten volunteers, which was then irradiated with UV, the scientists concluded that the antioxidant mix significantly helped to protect against UV damage.
Phloretin—new to the sun scene
According to the team, a significant body of literature supports the protective role of both vitamin C and ferulic acid. However, phloretin, is a new addition to the antioxidant sun protection portfolio.
Previous studies on plant phenol compounds illustrated that phloretin, which is found in the flesh and skin of apples, is particularly good at getting through the skin barrier. As bioavailablity is one of the major problems plaguing many antioxidant compounds, this characteristic makes phloretin very attractive, the scientists explained.
