from ultraviolet injury by green tea polyphenols.
Also, melanin levels have been shown to be inversely correlated with the amount of shin DNA damage induced by UV; therefore, it seems that white Caucasians low pigmentation capacity is responsible for a failure in intrinsic photoprotection

The qP reflects the photosynthetic activity, while the NPQ reflects the photoprotection

In the present study the diurnal changes in gas exchange and chlorophyll fluorescence were examined in leaves of ginkgo in order to describe their midday photoinhibition and photoprotection
under field conditions.
Thus, the aim of this study was to investigate the photoprotective efficacies, including UV protection, UVB/UVA balance protection and photostability, in a panel of commercially popular sunscreens available in self-service stores in Latin America by determining the internationally accepted indices of photoprotection
in an in vitro system.
Multivariate analysis was performed using robust Poisson regression applying the hybrid method to estimate the extent of the relationship between independent variables (sex, employment status, years of schooling, time of daily sun exposure, work start time, work finishing time, photoprotection
measures, sunscreen use, use of a cap/hat and skin type) and the dependent variable.
and adequate use of sunscreens may be associated with vitamin D insufficiency.
Melanocyte loss reduces melanin-derived photoprotection
of the skin and can compromise cutaneous immunity.
