Kalelo mu 2012, panali malangizo angapo atsopano, chachikulu chinali chakuti mafomu oteteza ku kuwala kwa UVA ndi UVB amalembedwa ngati sipekitiramu yayikulu. Kupatula apo, komabe, malamulo oyendetsera mafuta oteteza dzuwa ndi akale.

Lowetsani lamulo laposachedwa la FDA, lomwe lingakwaniritse zosintha zazikulu pagulu lonse lazogulitsa. Zina mwazo: zofunikira zolembera zosinthidwa, komanso kuyika SPF yayikulu kwambiri pa 60+, chifukwa chosowa deta yowonetsa kuti chilichonse choposa izi (ie, SPF 75 kapena SPF 100) chimapereka zopindulitsa zina zilizonse. Padzakhalanso kusintha kwamitundu yanji yazogulitsa yomwe ingatchulidwe ngati zotchinga dzuwa. Mafuta, mafuta odzola, mafuta odzola, timitengo, zopopera, ndi ufa akhoza, koma zinthu monga zopukutira ndi zopukutira (zomwe sizimaphunziridwa mochepa motero sizikutsimikiziridwa kuti ndizothandiza) sizidzagweranso m'gulu la sunscreen ndipo m'malo mwake zidzatengedwa ngati "zatsopano". mankhwala."

Kusintha kwina kwakukulu komwe kumapangitsa aliyense kulira ndikuthana ndi mphamvu yazogwiritsa ntchito zoteteza ku dzuwa. Pofufuza 16 mwazofala kwambiri, ma zinc-oxide awiri ndi titanium dioxide-okha ndi omwe amati ndi GRASE. Ndilo tanthauzo la FDA "lodziwika bwino kuti ndi lotetezeka komanso lothandiza." Awiri adawonedwa ngati osagwira ntchito, ngakhale izi ndi zopangira zakale zomwe pafupifupi palibe makampani omwe amagwiritsa ntchito, akutero Steven Q. Wang, M.D., wapampando wa Skin Cancer Foundation Photobiology Committee. Izi zimasiya khumi ndi awiri omwe akufufuzidwabe; izi ndi zosakaniza zomwe zimapezeka muzoteteza dzuwa, zomwe zambiri zimakhala ndi zovuta zina zowazungulira; Mwachitsanzo, oxybenzone ingawononge miyala yamchere yamchere. :

Skin Cancer Foundation ili m'bwalo ndi zosintha zomwe zingatheke. "Monga sayansi ndi ukadaulo wapita patsogolo pazaka zingapo zapitazi kuti zikwaniritse bwino magwiridwe antchito a zoteteza ku dzuwa, kupitiliza kuwunika malamulo omwe akukhudzidwa ndikofunikira, monganso kuwunika kwa zosefera zatsopano za UV zomwe zikupezeka kunja kwa US," adatero. mu chiganizo.

"Malinga ndi malingaliro a dermatologist, ndikuganiza kuti revamp iyi ndi chinthu chabwino," masekondi a Mona Gohara, MD, akuyanjana ndi pulofesa wazachipatala ku Yale School of Medicine. "Ndikofunikira nthawi zonse kuyang'anitsitsa zoteteza dzuwa ndi zomwe timalimbikitsa anthu, pogwiritsa ntchito deta yovomerezeka ya sayansi." (FYI, ndichifukwa chake Dr. Gohara akuti "mapiritsi oteteza dzuwa" ndi lingaliro loyipa kwambiri.)

Ndiye kodi zonsezi zikutanthauza chiyani kwa inu? Ndikofunika kuzindikira kuti zosintha zonsezi zikungoperekedwa pakali pano ndipo zingatenge nthawi kuti chigamulo chomaliza chifikire, akutero Dr. Wang. Koma ngati malangizo atsopanowa ayamba kugwira ntchito, zikutanthauza kuti kugula zoteteza ku dzuwa kumakhala kosavuta komanso kowonekera; mudzadziwa zomwe mukupeza komanso momwe zimatetezera khungu lanu.

Pakadali pano, a Dr. Gohara akuwonetsa kuti musamadziphatike ndi zoteteza ku dzuwa za mchere (ndipo kumbukirani, kuti muteteze kwambiri, Skin Cancer Foundation ikulimbikitsa njira yayikulu yokhala ndi SPF 30). "Amagwiritsa ntchito zosakaniza zomwe zatsimikiziridwa, osakayikira za izo, ndikuti FDA yawona kuti ndi yotetezeka komanso yothandiza," akutero.

Osanena kuti mafomulowa amapereka maubwino ena, monga kutetezedwa ku kuwala kowonekera, komanso kukhala ocheperako kuyambitsa kukwiya ndi kuzimiririka, akuwonjezera. (Ngati mukuyang'ana njira yabwino, mawonekedwe otetezera dzuwa a Murad ndi imodzi mwazomwe timachita.)

Ndipo, ndithudi, nthawi zonse ndi bwino kusuntha kuti mugwirizane ndi chizoloŵezi chanu chanthawi zonse choteteza dzuwa pochita makhalidwe ena otetezera dzuwa, monga kukhala pamthunzi ndi kuvala zovala zodzitetezera, kuphatikizapo zipewa ndi magalasi, anatero Dr. Wang.
