| contents | An important step towards the comprehensive sun protection: Blue‐light exposure inhibits DNA repair in reconstituted human skin and a broadband sunscreen avoids this inhibition Paulo Newton Tonolli Mauricio S. Baptista Photochemistry and Photobiology AbstractThe field of sun protection is quickly changing and the research article by Douki et al., published in the current issue of Photochemistry and Photobiology, reported key experimental data that will certainly help the development of better sun care products. Mutagenic photoproducts (CPDs, cyclobutane pyrimidine dimers and 6‐4PPs, pyrimidine‐6‐4‐pyrimidone photoproducts) were formed in the reconstructed human epidermis (RHE) by UVB (312 nm) irradiation, and their concentrations were detected by HPLC‐MS/MS as a function of time after the UVB treatment. RHE had been previously exposed or not (control) to blue light (427 nm). Both CPDs and 6‐4PPs were shown to last longer in blue‐light irradiated RHE, proving the inhibition of the DNA repair by blue light exposure. This is a highly relevant information because sunscreens allow people to enjoy longer periods under the sun and consequently, to endure very high doses of blue light. The work also reported results obtained with RHEs previously treated with a sunscreen formulation containing a broadband filter that offers blue‐light protection. Interestingly, authors observed that the DNA repair was not significantly inhibited in RHE previously treated with the sunscreen offering broadband protection. Readers will find a scientifically sound proof of the importance of blue‐light protection in sun care products. 10.1111/php.13979 http://onlinelibrary.wiley.com/termsAndConditions#vor |
