Editing Sunscreen (section)

== Research and development ==
New products are in development such as sunscreens based on [[bioadhesive]] nanoparticles. These function by encapsulating commercially used UV filters, while being not only adherent to the skin but also non-penetrant. This strategy inhibits primary UV-induced damage as well as secondary free radicals.<ref>{{cite journal | vauthors = Deng Y, Ediriwickrema A, Yang F, Lewis J, Girardi M, Saltzman WM | title = A sunblock based on bioadhesive nanoparticles | journal = Nature Materials | volume = 14 | issue = 12 | pages = 1278–1285 | date = December 2015 | pmid = 26413985 | pmc = 4654636 | doi = 10.1038/nmat4422 | bibcode = 2015NatMa..14.1278D }}</ref> UV filters based on [[Sinapinic acid|sinapate]] [[ester]]s are also under study.<ref>{{cite journal | vauthors = Horbury MD, Holt EL, Mouterde LM, Balaguer P, Cebrián J, Blasco L, Allais F, Stavros VG | display-authors = 6 | title = Towards symmetry driven and nature inspired UV filter design | journal = Nature Communications | volume = 10 | issue = 1 | pages = 4748 | date = October 2019 | pmid = 31628301 | pmc = 6802189 | doi = 10.1038/s41467-019-12719-z | s2cid = 204757709 | bibcode = 2019NatCo..10.4748H }}</ref> Sunscreens with natural and sustainable connotations are increasingly being developed, as a result of increased environmental concern.<ref>{{Cite journal |last1=Tortini |first1=Guido |last2=Ziosi |first2=Paola |last3=Cesa |first3=Elena |last4=Molesini |first4=Sonia |last5=Baldini |first5=Erika |last6=De Lucia |first6=Daniela |last7=Rossi |first7=Caterina |last8=Durini |first8=Elisa |last9=Vertuani |first9=Silvia |last10=Manfredini |first10=Stefano |date=June 2022 |title=Criticisms in the Development of High-Protection and Broad-Spectrum "Natural/Organic" Certifiable Sunscreen |journal=Cosmetics |language=en |volume=9 |issue=3 |pages=56 |doi=10.3390/cosmetics9030056 |issn=2079-9284 |doi-access=free |hdl=11392/2496193 |hdl-access=free }}</ref>
