Nthawi zambiri sungathe kuziwona ndipo mwina suzimva, koma pali zinyalala zambiri zomwe zikuyandama mumlengalenga. Monga tikuphunzirira, zikumenya khungu lathu mwamphamvu. M'zaka zingapo zapitazi, asayansi akhala akuphunzira za zotumphukira zamagetsi, mpweya, ndi zida zina zouluka zouluka zomwe zikuzungulira mizinda yathu, ndipo zikuwonekeratu kuti zowonongekazi zikutikalamba.

Limodzi mwa maphunziro okhutiritsa kwambiri, omwe adachitika ku Leibniz Research Institute for Environmental Medicine ku Germany, adawona momwe azimayi pafupifupi 2,000 adasochera atakhala zaka 30 atakhala ndi mpweya wowopsa mdera lawo lodetsedwa. "Tinapeza kugwirizana kwakukulu pakati pa mawanga a pigmentation pamasaya awo ndi kuipitsidwa kwakukulu," akutero Jean Krutmann, M.D., mkulu wa bungweli. Makamaka, amayi omwe adakumana ndi zinthu zambiri, monga mwaye ndi kuipitsidwa kwa magalimoto, anali ndi mawanga azaka 20% komanso makwinya owoneka bwino kuposa omwe amakhala kumidzi. Chiyambire kufalitsa izi mu 2010, akatswiri aphunzira zambiri za momwe kuipitsa madzi kumatipangitsa kukalamba. Ndipo zomwe awulula zitha kukulimbikitsani kuti mukulitse chisamaliro chanu pakhungu.

Mgwirizano Wowononga-Kukalamba

Asayansi ochokera ku Olay, L'Oréal, ndi makampani ena akuluakulu azodzikongoletsera ayambanso kuwona kulumikizana pakati pa kuipitsa ndi mavuto akhungu. Kafukufuku wina wa Estée Lauder, wofalitsidwa mu Zolemba za Investigative Dermatology, idawonetsa kuti tinthu tating'onoting'ono timayambitsa kupsinjika kwa khungu m'thupi, zotsatira za mamolekyulu owononga ngati ma radical aulere opitilira muyeso wanu wa chitetezo ndikuchepetsa kuwonongedwa kwa DNA, komwe kumatha kubweretsa zizindikilo zakukalamba msanga.

Monga momwe dzinalo likusonyezera, tinthu tating'onoting'ono (PM) ndi fumbi lochepa kapena mwaye tinthu tating'onoting'ono tazitsulo, ma carboni, ndi mankhwala ena; magwero ake ndi utsi wa galimoto ndi utsi wotenthetsera zinyalala. (Popeza pali zonyansa zambiri kunja, onetsetsani zomwe mukuyika mkati Ndibwino kwa khungu lanu nanunso, monga izi 8 Zakudya Zabwino Kwambiri Zakhungu.)

"Tikudziwa kuti kupsinjika kwa oxidative chifukwa cha zowonongekazi kumawononga khungu," akutero a Yevgeniy Krol, director science for SkinCeuticals. Izi ndichifukwa choti kukula kwa PM kumawathandiza kulowa mosavuta pakhungu. Zimakhala zoipitsitsa: "Thupi lanu limayankha kuipitsidwa mwa kuonjezera kuyankhidwa kotupa. Kutupa kumathandiza kuwononga anthu oipa komanso zonse zomwe zikuzungulira, kuphatikizapo collagen ndi elastin zomwe zimathandizira khungu lanu, "akutero Krol. "Ndiye ndiwe wawiri."

Zisanu Zoyipa

Particulate matter ndi imodzi mwa mitundu isanu yowononga mpweya yomwe imayambitsa kupsinjika kwa okosijeni komanso kutikalamba. China, pamwamba ozone-aka. utsi-uli ndi poizoni, Krol akutero. Mpweya wa ozoni umapangidwa pomwe ziwiri mwa zoyipitsa zisanu zazikuluzikulu, mankhwala osakanikirana (VOCs) ndi nitrogen oxide, osakanikirana ndi khungu lina la nemesis, ma ultraviolet (UV). Ma VOC ndi mankhwala omwe amatulutsidwa mu utsi wamagalimoto, utoto, ndi mpweya wochokera ku mafakitale; Mpweya wa nitrogen oxide umachokera ku mafuta oyaka, monga magalimoto kapena mafakitale. Kutulutsa quintet yodziwika bwino ndi ma polycyclic onunkhira a hydrocarbon, mankhwala omwe amapezeka muutsi komanso, utsi wagalimoto.

Nkhondo Yamankhwala

Pamene mukuyenda ndi magalimoto, tinthu tosiyanasiyana tosaoneka timatha kumamatira ndikulowa pakhungu lanu. PM nthawi zambiri amayeza pa 2.5 mpaka 10 microns, ndipo ma pores amakhala pafupifupi 50 microns. Zili ngati kukhala ndi cholinga chotseguka.

Zomwe zimachitika ndiye: Masitolo anu a antioxidants achilengedwe amalumikizana kuti atulutse mamolekyulu owononga. Koma izi zimawononga njira yanu yodzitetezera, ndikusiya khungu kukhala lopanda zida zolimbana ndi kuwonongeka kwina, ndipo pamapeto pake kumabweretsa kupsinjika kwa okosijeni-kutupa nkhonya imodzi ndi ziwiri zomwe Krol adalankhula. (Izi zopatsa chidwi ku Korea Zogulitsa Zabwino zitha kuthandizira khungu lanu kubwerera.)

Koma zimenezo ndi mbali chabe ya vuto. Kuwonongeka kumayambitsa kusintha kwa majini, akutero Wendy Roberts, M.D., dokotala wa khungu ku Rancho Mirage, California, amene anafufuza mmene kuipitsa khungu kumakhudzira. PM imapangitsa kuti magwiridwe antchito a cell azipita haywire, ndikutumiza ma cell opangira utoto mu overdrive. Kuphatikiza apo, PM kuchokera kumagalimoto amayambitsa michere yambiri yomwe imawononga collagen ndikuyambitsa ma peptide, zomwe zimabweretsa kupanga mitundu yambiri ya utoto.

Pakadali pano, ozoni, makamaka, imawononga khungu; imagwiritsa ntchito lipids ndi mapuloteni omwe amachititsa kuti khungu lanu likhale ndi madzi ndipo chotchinga chanu chikhale cholimba. Zotsatira zake, nkhope yanu imawuma, ndipo kuwonongeka kumatsegula chitseko choti mankhwala obwera ndi mpweya alowe. Ponyani kuwonekera kwa UV, zomwe zimapangitsa PM kukhala yotakataka, ndipo lingaliro lokhala pagululi limakhala losangalatsa. (Mutha kuteteza khungu lanu padzuwa ndi ma Sunscreen Opambana Oteteza Khungu.)

Momwe Mungapangire Zowonongeka

Mwamwayi, simuyenera kusiya moyo wamatauni kuti muchepetse kukalamba. Choyamba, tsukani nkhope yanu usiku. PM imadziunjikira pakhungu pa nthawi ya tsiku, ndipo ikakhala nthawi yayitali komanso yowonjezereka, zotsatira zake zimakhala zovuta kwambiri, Dr. Roberts akuti.

• Gwiritsani ntchito kirimu wa tsiku wofatsa, wofewetsa monga Clarins Multi-Active Cream.
• Pambuyo pake, ikani antioxidant yapamwamba, yomwe ingalimbikitse gulu lanu lankhondo lamkati la olimbana ndi kuipitsa. Fufuzani omwe ali ndi ferulic acid kapena vitamini C, monga Lumene Bright Tsopano Vitamini C Hyaluronic Essence.
• Chotsatira, sungani khungu lanu ndi chinyezi chokhala ndi niacinamide, yomwe imathandizira kupanga zotchinga zoteteza khungu, ndi vitamini E, yomwe imakhala ngati chitetezo choyamba. Olay Regenerist Micro-Sculpting Cream SPF 30 ili ndi zosakaniza zonse ziwiri.
• Usiku, gwiritsani ntchito mankhwala okhala ndi resveratrol. "Imayendetsa dongosolo la antioxidant la thupi lanu ndikumanga masitolo anu," akutero Krol. Ili mu SkinCeuticals Resveratrol B E Serum.
• Komanso, sinthani ku mafuta oteteza ku dzuwa okhala ndi zinki kapena titanium dioxide, monga Aveda Daily Light Guard Defense Fluid SPF 30. Amateteza ku kuwala kwa UV, komwe kungapangitse kuwonongeka komwe kumayambitsa. Kuvala maziko ndi zodzoladzola za ufa kumathandizanso, chifukwa zonsezi zimawonjezera chitetezo china ku kuipitsa, Dr. Roberts akutero.
• Zatsopano zolimbana ndi kuipitsa zikuperekanso njira zatsopano zoletsera zinthu zoyipa. Mwachitsanzo, Shiseido's Future Solution LX Total Protective Cream SPF 18 ili ndi ufa wosawoneka womwe umatsekera tinthu tating'onoting'ono toipitsa ndikuwaletsa kumamatira pakhungu. Tsatirani ndondomekoyi ndipo mudzawona kuti palibe chokongola kuposa khungu lomwe latetezedwa.
