Yize amafomula amasha efika emakethe ngaso sonke isikhathi, imithethonqubo ye-sunscreens-ehlukaniswa njengesidakamizwa futhi ngenxa yalokho ilawulwa yi-FDA-ihlale ingashintshi kakhulu kusukela ngawo-90s. Ngakho-ke ngenkathi ukukhetha kwakho kwemfashini, isitayela sakho sezinwele, kanye nayo yonke eminye imithetho yokunakekelwa kwesikhumba kungenzeka ukuthi yavela kusukela lapho, 'isikrini sakho sisabambekile esikhathini esedlule.

Emuva ngo-2012, kwakukhona imihlahlandlela emisha embalwa, enkulu kunazo zonke ukuthi amafomula avikela kuyo yomibili imisebe ye-UVA ne-UVB abhalwe njengobubanzi obubanzi. Ngaphandle kwalokho, noma kunjalo, imithetho elawula ama-sunscreen iyindatshana ethile.

Faka umthetho ophakanyisiwe wakamuva we-FDA, ozosebenzisa izinguquko ezithile ezinkulu kusigaba sonke somkhiqizo. Phakathi kwazo: izidingo zokulebula ezibuyekeziwe, kanye nokufaka isilinganiso esiphezulu se-SPF kuma-60 +, ngenxa yokushoda kwedatha ekhombisa ukuthi noma yini ngaphezulu kwalokhu (okungukuthi, i-SPF 75 noma i-SPF 100) inikela nganoma yiluphi uhlobo lwezinzuzo ezengeziwe ezinenzuzo. Kungase futhi kube noshintsho ekutheni iziphi izinhlobo zemikhiqizo empeleni ezingahlukaniswa njengezokuvikela ilanga. Amafutha, okhilimu, ama-lotion, izinti, izifutho, kanye ne-powders kuyenzeka, kepha imikhiqizo efana nokusula nama-towelette (angafundwa kancane futhi ngenxa yalokho okungaqinisekisiwe ukuthi iyasebenza) ngeke isaba ngaphansi kwesigaba se-sunscreen futhi esikhundleni salokho izothathwa njenge "entsha" umuthi. "

Olunye ushintsho olukhulu olwenziwa yibo bonke abantu ababhekayo lubhekisa ekusebenzeni kahle kwezithako ezisebenza ngokuvikela isikrini selanga. Ekutadisheni okungu-16 kokuvame kakhulu, yi-zinc-oxide ne-titanium dioxide kuphela-kuphela ethathwe njenge-GRASE. Leyo yingqondo ye-FDA "eyaziwa ngokuvikelekile futhi esebenzayo." Amabili athathwa njengangasebenzi, yize lezi kuyizithako esezaphelelwa yisikhathi cishe ezazingasetshenziswa zinkampani, kuphawula uSteven Q. Wang, MD, ongusihlalo we-Skin Cancer Foundation Photobiology Committee. Lokho kushiya ishumi nambili elisaphenywa; lezi izithako ezitholakala emishinini yokuzivikela elangeni yamakhemikhali, eminingi yayo enezinye izingxabano ezizungezile; I-oxybenzone, ngokwesibonelo, ingalimaza izixhobo zamakhorali.

ISkin Cancer Foundation ikhona kulezi zinguquko ezingaba khona. "Njengoba isayensi nobuchwepheshe sekuthuthukile eminyakeni eminingana edlule ukuze kuthuthukiswe ngokuphumelelayo ukusebenza kahle kwezigcoba zelanga, kuqhubeka ukuhlolwa kwemithetho ehambisana nazo kuyadingeka, njengoba kunjalo nokuhlolwa kwezihlungi ezintsha ze-UV ezikhona njengamanje ngaphandle kwase-US," kusho bona. esitatimendeni.

"Ngokubuka kukadokotela wesikhumba, ngicabanga ukuthi lokhu kuvuselelwa kuyinto enhle," imizuzwana uMona Gohara, MD, uhlobanisa noprofesa wezokwelapha e-Yale School of Medicine. "Kubalulekile ukuthi sihlale sihlola izinto zokuvikela ilanga kanye nalokho esikuncoma kubantu, ngokusekelwe kudatha yesayensi esemthethweni." (I-FYI, yingakho uDkt Gohara ethi "amaphilisi elanga elangeni" empeleni kuwumqondo omubi.)

Ngabe konke lokhu kusho ukuthini kuwe? Kubalulekile ukuthi wazi ukuthi zonke lezi zinguquko zihlongozwayo okwamanje futhi kungathatha isikhathi ukuthi isinqumo sokugcina sitholakale, kusho uDkt Wang. Kepha uma le mihlahlandlela emisha iqala ukusebenza, kusho ukuthi ukuthenga i-sunscreen kuzoba lula kakhulu futhi kube sobala; uzokwazi kahle ukuthi uthola ini nokuthi isivikela kanjani isikhumba sakho.

Khonamanjalo, uDkt. Gohara uphakamisa ukunamathela ezikhunjeni zelanga zamaminerali (futhi khumbula, ukuze uvikeleke ngempumelelo kakhulu, iSkin Cancer Foundation incoma ifomula elibanzi eline-SPF 30). "Basebenzisa izithako ezifakazelwe, akukho mbuzo ngakho, nokuthi i-FDA ibone ukuthi iphephile futhi iyasebenza," esho.

Ukungasho ukuthi lawa mafomula ahlinzeka ezinye izinzuzo, okuwukuthi ukuvikelwa ekukhanyeni okubonakalayo, futhi ngokujwayelekile ukuthi mancane amathuba okudala ukucasuka nokuphuka, uyanezela. (Uma ufuna inketho enhle, lesi sikrini selanga se-Murad esenza imisebenzi eminingi singesinye sezihambeli zethu.)

Futhi, kunjalo, kuhlale kuwumnyakazo omuhle ukuhambisana nomkhuba wakho ovamile wokuvikela ilanga ngokuzijwayeza ezinye izindlela zokuzivikela elangeni, njengokuhlala emthunzini nokugqoka izingubo zokuzivikela, okuhlanganisa izigqoko nezibuko, kuphawula uDkt. Wang.
