Ngexesha lasehlotyeni, ngowona mbuzo ubaluleke ngaphezu ko "yeyiphi indlela eya elwandle?" ngu "Ingaba kukho umntu oze nesunscreen?" Umhlaza wolusu ayisiyonto yokuhlekisa: Amaxabiso e-melanoma athe anyuka kule minyaka ingama-30 idlulileyo, kwaye ikliniki yaseMayo kutshanje inike ingxelo yokuba zimbini iintlobo zomhlaza wolusu ezanyusa umhlathi-wehla nge-145 yeepesenti kunye neepesenti ezingama-263 ukusuka ngo-2000 ukuya ku-2010.

Ngelixa sisazi ukuba i-sunscreen inceda ukukhusela kumhlaza wolusu, unokuba ukhusela ulusu lwakho ngendlela engaphantsi kunokuba ucinga ngokukhetha ngokungazi ifomula engalunganga. IQela eliSebenzayo lokusiNgqongileyo (EWG) lisanda kukhupha isikhokelo sonyaka we-2017 se-sunscreen, isilinganiselo malunga neemveliso ze-1,500 ezibhengezwe njengokhuseleko lwelanga lokhuseleko kunye nokusebenza kakuhle. Bafumene i-73 yeepesenti yeemveliso ayizange isebenze kakuhle, okanye iqulethwe malunga nezithako, kuquka iikhemikhali ezibotshelelwe ukuphazamiseka kwehomoni kunye nokucaphuka kwesikhumba.

Abaphandi babo bathi nangona uninzi lwabantu lujolise kwi-SPF ephezulu, eyona nto kufanele ukuba bajonge kuyo zizithako ezikwibhotile. Iimpawu ezingaphantsi zinokubakho ezinobungozi okanye ezinokucaphukisa iikhompawundi ziwela kudidi olubizwa ngokuba yi-mineral-based, okanye "yendalo," izithambisi zelanga.

Kuyabonakala ukuba, uninzi lwenu sele lunomdla wolu didi: Uphononongo lweeNgxelo zabaThengi lowama-2016 lafumanisa ukuba phantse isiqingatha sabantu abali-1 000 ekwenziwe uhlolisiso kubo bathi bajonge imveliso "yendalo" xa bethenga i-sunscreen. Kodwa ngaba ii-sunscreen zendalo zinokulingana ngokwenyani nokhuseleko olukhutshwa ziifomula zamachiza?

Okumangalisayo kukuba, iidermatologists ezimbini ziyaqinisekisa ukuba ziyakwazi. Nantsi into ekufuneka uyazi.

Yintoni Kwifomula Yezimbiwa?

Umahluko phakathi kwendabuko, i-sunscreens-based based sunscreens kunye neentlobo zamaminerali zehla kuhlobo lwezithako ezisebenzayo. Iikhrim ezisekwe kwizimbiwa zisebenzisa i-blocker-zinc oxide kunye / okanye i-titanium dioxide-eyenza isithintelo kulusu lwakho kwaye ibonakalisa imitha ye-UV. Abanye basebenzisa iibhlokhi blocker -yindibaniselwano ye-oxybenzone, avobenzone, octisalate, octocrylene, homosalate kunye / okanye i-octinoxate-efunxa imitha ye-UV ukuyichitha. (Siyazi, ngumlomo!)

Kukwakho neentlobo ezimbini zemitha ye-UV: I-UVB, enoxanduva lokoqobo lokutshiswa lilanga, kunye nemitha ye-UVA, engena nzulu. I-mineral-based, i-block blockers yomzimba ikhusela kuzo zombini. Kodwa ekubeni izithinteli zeekhemikhali zifunxa imitha endaweni yoko, oku kuvumela i-UVA ukuba ifikelele kulaa maleko anzulu olusu lwakho kwaye yenze umonakalo, uyacacisa uJeanette Jacknin, MD, iSan Diego-based holistic dermatologist kunye nombhali Unyango lwe-Smart kwiLusu lakho.

Ingxaki nge-Chemical Blockers

Enye inkxalabo enkulu kunye nabathinteli beekhemikhali yingcamango yokuba baphazamisa ukuveliswa kwehomoni. Le yinto isilwanyana kunye neeseli eziqinisekisiweyo, kodwa sifuna uphando oluthe kratya ebantwini ukusixelela ukuba lusebenza njani ngqo kwi-sunscreen (ingakanani ikhemikhali efunxwayo, ukuba ikhutshwe ngokukhawuleza kangakanani, njl.), Utshilo u-Apple Bodemer, MD, uprofesa wesikhumba kwiYunivesithi yaseWisconsin.

Kodwa izifundo kwezi khemikhali, ngokubanzi, ziyothusa ngemveliso ekufanele ukuba siyisasaze yonke imihla. Enye ikhemikhali ngokukodwa, i-oxybenzone, iye yanxulunyaniswa nomngcipheko ophezulu we-endometriosis kwabasetyhini, umgangatho ophantsi wesidoda emadodeni, ukwaliwa lusu, ukuphazamiseka kwehomoni, kunye nomonakalo weseli-kwaye i-oxybenzone yongezwa malunga neepesenti ezingama-65 zesunscreens ezingezizo iiminerali. i-EWG's database ye-2017 ye-sunscreen, uGqr. Jacknin wakhomba. Kwaye isifundo esitsha esivela eRashiya sapapashwa kwiphephancwadi Imichiza ifumene ukuba ngelixa ikhemikhali ye-sunscreen eqhelekileyo, i-avobenzone, ngokuqhelekileyo ikhuselekile ngokwayo, xa iimolekyuli zidibana namanzi e-chlorinated kunye nemitha ye-UV, ihlahlela ibe yi-compounds ebizwa ngokuba yi-phenols kunye ne-acetyl benzenes, eyaziwa ngokuba yityhefu emangalisayo.

Enye imichiza ekhathazayo: i-retinyl palmitate, enokubangela ukukhula kwamathumba kunye nezilonda xa zisetyenziswa kulusu elangeni, wongeza. Nangona kwiphepha elingaphantsi kwe-alarmist, i-oxybenzone kunye nezinye iikhemikhali zivame ukubangela iingxaki ngokuphendula kwesikhumba kunye nokucaphuka, ngelixa ezininzi iiminerali azikwenzi, uDkt Bodemer uthi-nangona wongezelela ukuba oku kungumcimbi nje wabantu abadala abanesikhumba esibucayi kunye nabantwana. .

Ke ngaba zonke iiCream eziSekwe kwiMineral zingcono?

I-Mineral-based creams iyinto engokwemvelo, kodwa kunye nezithako zabo ezicocekileyo zihamba kwinkqubo yeekhemikhali ngexesha lokuqulunqwa, uDkt Bodemer ucacisa. Kwaye ezininzi ze-sunscreens ezisekelwe kwiminerali zinezithinteli zeekhemikhali kuzo, nazo. "Akuqhelekanga ukufumana indibaniselwano yezithinteli zomzimba kunye neekhemikhali," uyongezelela.

Oko kuyathethwa, kuba sisazi okuncinci malunga nokuba zeziphi iibhlokhemikhali ezenza ngokwenene kwimizimba yethu, zombini ezi ngcali ziyavuma ukuba ukubheja kwakho okungcono kukufikelela kwizithambiso zelanga zezimbiwa ngeebhloko blocker, ngakumbi ukuba unesikhumba esibuthathaka.

Ukhuseleko oluphezulu luza ngexabiso eliphezulu, nangona: "Eyona nto iphambili kukuba uninzi lweescreen zendalo ezinokuxinana okuphezulu kwe-zinc kunye ne-titanium dioxide zimhlophe kakhulu kwaye azikho mnandi," utshilo uGqirha Jacknin. (Cinga abo badlala emanzini ngomgca omhlophe wehla ngeempumlo zabo.)

Ngethamsanqa, abavelisi abaninzi bakuphikisile oku ngokuphuhlisa iifomula ezinama-nanoparticles, anceda i-titanium dioxide emhlophe ijongeke ngokungafihlisiyo kwaye inike ukhuseleko olungcono lwe-SPF-kodwa ngexabiso lokhuselo olubi lwe-UVA, utshilo uGqirha Jacknin. Ngokufanelekileyo, i-formula ine-balance ye-zinc oxide particles enkulu yokukhusela i-UVA enkulu, kunye neencinci ezincinci ze-titanium dioxide ukuze imveliso ihambe ngokucacileyo.

Yintoni ekufuneka ujonge kuyo

Ngelixa ii-sunscreens zeminerali zihlala zingcono kulusu lwakho, Njani ngcono ngakumbi kuxhomekeke kwinto engaphakathi ngaphakathi. Njengokupakisha ukutya, igama "yendalo" kwileyibhile ayinabunzima. "Zonke izinto zokuthambisa ilanga zinemichiza kuzo, nokuba zithathwa njengendalo okanye akunjalo. Indlela eziyindalo ngayo ixhomekeke kuphawu," utshilo uGqirha Bodemer.

Jonga i-sunscreens enezithako ezisebenzayo i-zinc oxide kunye ne-titanium dioxide.Mhlawumbi uya kufumana olona khetho lubalaseleyo kwivenkile yangaphandle okanye kwivenkile yokutya okukhethekileyo kwezempilo, kodwa neempawu ezifumaneka kwindawo zonke ezifana ne-Neutrogena kunye ne-Aveeno zineefomyula ezisekwe kwiminerali. Ukuba awufumani ezi shelufini, okulandelayo kukuphepha abo baneekhemikhali ezithi inzululwazi ziyingozi kakhulu: i-oxybenzone, i-avobenzone kunye ne-retinyl palmitate. (Ingcebiso yePro: Ukuba unesikhumba esibucayi, khangela iibhotile ezibhalwe ngabantwana, uDkt Bodemer uyabelana.) Ngokuphathelele izithako ezingasebenziyo, uGqr. , njengoko ezi zihlala ixesha elide ngokubila nangamanzi. Kwaye ngelixa uninzi lwethu lufundiswa ukukhangela i-SPF, i-FDA ibiza i-SPF ephezulu "iyalahlekisa ngokwemvelo." I-EWG ibonisa ukuba kusebenza ngakumbi ukusebenzisa i-sunscreen ephantsi ngokufanelekileyo kunesiqingatha sentliziyo ephezulu. UDkt Bodemer uyaqinisekisa: Yonke i-sunscreen iya kuguga, ngoko ke kungakhathaliseki ukuba i-SPF okanye izithako ezisebenzayo, kufuneka uphinde usebenzise ubuncinane kwiiyure ezimbini. (I-FYI nazi ezinye iindlela zokhuselo elangeni ezimele ukuvavanywa kokubila kwethu.)

Kwaye nangona kunokuba nzima ukunxiba, kungcono ukuba unamathele kwi-lotion-ezo nanoparticles ezinciphisa uburharha zikhuselekile ngokubanzi, kodwa zinokubangela umonakalo emiphungeni ukuba uziphefumlela kwifomula yesitshizi, uGqr Jacknin wongeza. Esinye isicelo esibalulekileyo kwi-FYI: Ngenxa yokuba i-sunscreen ye-mineral ikhusela ngokwenza umqobo, ufuna ukuthambisa i-15 ukuya kwimizuzu engama-20 ngaphambi kokuba uphume-phambi kokuba uqale ukushukuma kunye nokubila-ukuqinisekisa ukuba unefilimu elinganayo eluswini lwakho xa ubetha ilanga. , Ugqirha Bodemer utsho. (Kuhlobo lwekhemikhali, yibeke kwimizuzu engama-20 ukuya kwengama-30 phambi kokutshiswa lilanga ukuze ibe nexesha lokungena ngaphakathi.)

Amaxabiso e-EWG lonke uphawu lwe-sunscreen yokusebenza kunye nokhuseleko, ke jonga kwindawo yokugcina idatha ukuze ubone ukuba ifomula yakho oyithandayo iwela phi. Iimpawu ezimbalwa zethu esizithandayo ezidibana nezikhokelo zezi derms kunye ne-EWG: Beyond Coastal Active Sunscreen, Badger Tinted Sunscreen, kunye neNeutrogena Sheer Zinc Dry-Touch Sunscreen.

Khumbula ukuba, nangona kunjalo, nayiphi na uhlobo lwelanga lungcono kunoko hayi i-sunscreen. "Siyazi ukuba imitha ye-UV sisifo somhlaza somntu-ngokuqinisekileyo ibangela uhlobo lomhlaza wolusu olunganyangwa yi-melanoma. "Ugqirha Bodemer wongeza.
