Ngaphandle kwento yokuba iifomula ezintsha zifika kwintengiso ngalo lonke ixesha, imigaqo ye-sunscreens-ehlelwa njengechiza kwaye ilawulwa yi-FDA-ihlala ingatshintshanga ukusukela nge-90s. Ke ngelixa ukhetho lwakho lwefashoni, iinwele zakho, kunye nayo yonke inkqubo yokhathalelo lolusu kungenzeka ukuba yavela ukusukela ngoko, isikrini sakho sisabambekile kwixesha elidlulileyo.

Emuva ngo-2012, bekukho izikhokelo ezitsha ezimbalwa, eyona iphambili kukuba iifomula ezikhuselayo kwimitha ye-UVA kunye ne-UVB zibhalwe njengomboniso obanzi. Ngaphandle koko, nangona kunjalo, imithetho elawula i-sunscreens yinto yakudala.

Ngenisa umthetho we-FDA wamva nje, oya kuthi uzalisekise utshintsho olukhulu kudidi lonke lwemveliso. Phakathi kwazo: iimfuno zokulebhelisha ezihlaziyiweyo, kunye nokubhala eyona SPF iphezulu kwi-60 +, ngenxa yokunqongophala kwedatha ebonisa ukuba nantoni na engaphezulu koku (okt, i-SPF 75 okanye i-SPF 100) ibonelela ngalo naluphi na uhlobo lwezibonelelo ezongezelelweyo ezinentsingiselo. Kwakhona kuya kubakho utshintsho kwiintlobo zeemveliso ezinokuhlelwa njenge-sunscreen. Iioyile, iikhrimu, into yokuthambisa, izinti, iipreyiza, kodwa iimveliso ezinje ngeesula kunye neetawuli (ezingafundiswanga kangako kwaye ezingqinisisiweyo ukuba ziyasebenza) azisayi kuwa phantsi kodidi lwelanga kwaye endaweni yoko ziya kuthathwa njenge "entsha" iziyobisi. "

Olunye utshintsho olukhulu olunaye wonke umntu obhuzayo lujongana nokusebenza kwezithako ezisebenzayo ze-sunscreen. Ekufundeni i-16 yezona zixhaphakileyo, zimbini kuphela i-zinc oxide kunye ne-titanium dioxide-zithathwa njenge GRASE. Leyo yi-FDA lingo "eyaziwa ngokubanzi njengekhuselekile kwaye isebenza." Emibini yabonwa njengengasebenziyo, nangona ezi zizithako eziphelelwe lixesha eziphantse kungabikho nkampani zizisebenzisayo, uphawula uSteven Q. Wang, M.D., usihlalo weKomiti yeFotobiology yeSkin Cancer Foundation. Oko kushiya ishumi elinesibini lisaphantsi kophando; ezi zizithako ezifumaneka kwiikhemikhali zokuthambisa ilanga, uninzi lwazo olunezinye iingxabano ezibangqongileyo; Umzekelo, i-oxybenzone inokonakalisa iingqaqa zekorale. (Idibeneyo: Ngaba i-sunscreen yendalo ibambe ngokuchasene neLanga eliqhelekileyo elangeni?)

Isiseko seCancer Cancer sikhwele nolu tshintsho lunokubakho. "Njengokuba isayensi nethekhinoloji zihambile kwiminyaka eliqela edlulileyo ukuphucula ngamandla ukusebenza kweescreen, ukuqhubeka kovavanyo kwemigaqo enxulumene nazo kubalulekile, njengoko kunjalo nakuvavanyo lweefilitha ezintsha ze-UV ezikhoyo ngoku ngaphandle kwe-US," batsho. kwingxelo.

"Ngokombono wesikhumba, ndicinga ukuba le revamp yinto elungileyo," imizuzwana u-Mona Gohara, MD, unxulumana noprofesa wezonyango kwiYale School of Medicine. "Kubalulekile ukuba uphinde uphonononge ii-sunscreens kunye nento esiyincomayo ebantwini, ngokusekwe kwidatha yesayensi esemthethweni." (I-FYI, nasi isizathu sokuba uGqirha Gohara athi "iipilisi ezikhuselayo elangeni" ngokwenene luluvo olubi.)

Ngoko ke kuthetha ntoni konke oku kuwe? Kubalulekile ukuba uqaphele ukuba lonke olu tshintsho luphakanyisiwe nje ngoku kwaye kungathatha ixesha ukufikelela kwisigqibo sokugqibela, utshilo uGqirha Wang. Kodwa ukuba ezi zikhokelo zintsha ziyaqala ukusebenza, oko kuthetha ukuba ukuthenga i-sunscreen kuya kuba lula ngakumbi kwaye kubonakale ngakumbi; Uyakwazi ngokuthe ngqo into oyifumanayo kunye nendlela ekhusela ngayo ulusu lwakho.

Okwangoku, uGqirha Gohara ucebisa ngokubambelela kwizithambisi zelanga (kwaye khumbula, kokona kusebenza kukhuseleko, iScancer Cancer Foundation icebisa ifomula ebanzi ene-SPF 30). Basebenzisa izithako eziqinisekisiweyo, akukho mbuzo malunga nayo, kwaye i-FDA ibonwe njengekhuselekileyo kwaye iyasebenza, utshilo.

Ungakhankanyi ukuba ezi fomyula zinika ezinye izibonelelo, oko kukuthi ukukhuselwa ekukhanyeni okubonakalayo, kunye ngokuqhelekileyo kungenakwenzeka ukuba kubangele ukucaphuka kunye nokuphuka, uyongezelela. (Ukuba ujonge ukhetho olulungileyo, esi sikhuseli selanga seMurad sisenza izinto ezininzi sesinye seendlela zethu.)

Kwaye, kunjalo, kuhlala kuyinto elungileyo ukuxhasa umkhuba wakho wokuzikhusela elangeni ngokwenza ezinye iindlela zokuziphatha ezikhuselekileyo elangeni, ezinjengokuhlala emthunzini nokunxiba iimpahla zokuzikhusela, kubandakanya neminqwazi kunye nezibuko zelanga, utshilo uGqirha Wang.
