Timaphatikizapo zinthu zomwe timaganiza kuti ndizothandiza kwa owerenga athu. Ngati mutagula maulalo omwe ali patsamba lino, titha kupeza ndalama zochepa. Nayi njira yathu.

Makumi asanu ndi atatu pa zana aukalamba wowonekera amayamba ndi dzuwa

Kutuluka panja kukasangalala ndi tsiku lowala komanso thambo labuluu si nthawi yokhayo yodzitchinjiriza ku cheza cha dzuwa, koma ndi nthawi yovuta kwambiri kutero. Kupatula apo, kangati umakonda kupita panja? Mwina kamodzi patsiku.

Koma kodi mumadziwa kuti mpaka ukalamba wowoneka bwino umayamba chifukwa chakuwala kwa kuwala kwa dzuwa la UV? Osati mwa ukalamba wokha. Osati chifukwa cha kupsinjika, kusowa tulo, kapena magalasi amodzi a vinyo m'masabata ambiri kuposa momwe timafunira kuvomereza. Mizere yabwino ija ndi mawanga azaka? Ndizowonongeka kuchokera kudzuwa.

Tinayankhula ndi Dr.David Lortscher, dermatologist wotsimikizika ndi board komanso woyambitsa Curology, kuti mupeze chitsogozo chomaliza chodzitetezera ku cheza chachikulire cha UV ndikubwezeretsanso kuwonongeka kwa dzuwa kumaso kwanu.

Zolemba pambuyo paziphuphu, kuwongolera dzuwa

Kwa zaka zilizonse komanso nthawi yayikulu pachaka, nayi malamulo oti muzitsatira mukamayesetsa kuwononga dzuwa:

Malamulo atatu kutsatira:

1. Pa ma radiation a dzuwa omwe amafikira padziko lapansi, mpaka 95% ndi UVA, ndipo pafupifupi 5% ndi UVB. Mukufuna zotchinga dzuwa, tsiku lililonse chaka chonse, kuteteza motsutsana ndi onse awiri.
2. Dzuwa limatha kupangitsa kuti ziphuphu zizikhala zazikulu kwambiri; tetezani khungu lanu kuti mupewe zipsera zakuda zomwe zatsalira ndi ziphuphu.
3. Zosakaniza zina zomwe zimagwiritsidwa ntchito pozimitsa mawanga amdima zimatha kupangitsa khungu lanu kukhala lowopsa kwambiri kuwonongeka kwa dzuwa; khalani maso kwambiri ndi chitetezo cha dzuwa mukamawagwiritsa ntchito.

Izi sizikutanthauza kuti simungasangalale ndi nthawi panja, kaya ndi masiku otentha a chilimwe pagombe kapena masiku otentha a dzinja.

Chofunikira ndikukhazikitsa chizolowezi ndikudzipereka kuzolowera.

Kuwonongeka kwa dzuwa kumakhala pansi, ndikukula, ndipo kumatha kupha. Sikuti ndizopsa chabe. Kufufuta khungu ndi zizolowezi zake ndizowopsa.

Timafufuza mu sayansi kumbuyo kwa lamulo lililonse pansipa.

1. Gwiritsani ntchito zoteteza ku dzuwa kuti mudziteteze osapewa kunjaku

Mpaka 95 peresenti ya cheza chomwe chimapangitsa kuti chikhale padziko lapansi - ndi khungu lanu - ndi UVA. Kuwala uku sikulepheretsedwa ndi mitambo kapena magalasi. Chifukwa chake, kupewa kunjaku siyankho kwenikweni - kuphimba, makamaka ndi zotchinga dzuwa, ndilo.

U.S. Food and Drug Administration (FDA) ikulangiza kuti kuchepa kwa dzuwa “makamaka pakati pa 10 koloko mpaka 2 koloko masana, pamene kuwala kwa dzuwa kuli kwambiri,” kuphimba zovala, zipewa, ndi magalasi, komanso zowunikira.

Nayi chowonadi chokhudza zoteteza ku dzuwa: Powerengera simugwiritsa ntchito zokwanira popewa zizindikilo za ukalamba.

M'malo mwake, ngati mukuda nkhawa ndi malo omwe amafota, muyenera kukhala tcheru kwambiri! Mankhwala ambiri aziphuphu ndi mabala, kaya ndi mankhwala kapena owonjezera (OTC), amatha kupangitsa khungu lanu kukhala lowala kwambiri padzuwa.

Lortscher amalimbikitsa osachepera 30 SPF, ndipo tikulimbikitsanso kugwiritsa ntchito 1/4 tsp pankhope panu kuti muwonetsetse chitetezo cholonjezedwa pamndandanda.

Mavoti a SPF amatengera kugwiritsa ntchito. Izi zimagwira pafupifupi 1/4 tsp pankhope panu. Izi ndizochulukirapo kuposa momwe anthu amaganizira kuti amafunikira. Ngati simugwiritsa ntchito 1/4 tsp pankhope panu tsiku ndi tsiku, ganizirani kuyeza kuti muwone kuchuluka kwa zomwe muyenera kugwiritsa ntchito.

Ngati mukuda nkhawa kuti simukupeza vitamini D wokwanira popanda kuwonekera kwa UV, kambiranani zomwe mungachite ndi dokotala wanu. "Anthu ambiri amatha kutenga vitamini D yemwe amafunikira kuchokera ku zakudya kapena zowonjezera mavitamini," akufotokoza Dr. Lortscher. Zowonjezera zimatha kukhala njira yabwino yopezera vitamini D yomwe mukufuna popanda kuwonjezera chiopsezo cha khansa yapakhungu.

2. Gwiritsani ntchito zopangira izi kuti muchepetse kuwonongeka kwa dzuwa

Kupewa ndikosavuta kuposa kubwezera zikawononga dzuwa, koma pamenepo ali zosankha kunja uko zochizira zikwangwani zowoneka zokalamba kuwonongeka kwa dzuwa, zotchedwa photoaging.

Nsomba ndi: Muyenera kudzipereka kugwiritsa ntchito kuteteza dzuwa kwambiri musanagwiritse ntchito. Kupanda kutero, mudzakhala mukuchita zoyipa zambiri kuposa zabwino.

Musanayese mankhwala okalamba chifukwa cha mizere yabwino, kapangidwe kovutirapo, ndi kuchuluka kwa mafunde, dzifunseni:

• Kodi mukupewa kutentha kwa dzuwa?
• Kodi mukubisa khungu lowonekera povala zipewa, magalasi, ndi zovala zoyenera?
• Kodi mumagwiritsa ntchito zoteteza ku dzuwa nthawi zonse?

Ngati mayankho anu ndi inde kwa zonsezi, ndiye kuti mwakonzeka kuyenda mzere wabwino wobwezeretsa kuwonongeka kwa dzuwa. Nayi nyenyezi zomwe Curology imagwiritsa ntchito m'njira zawo zamankhwala:

1. Niacinamide

4. Vitamini C

“[Ichi] ndichipangizo chapamwamba kwambiri chomwe chimathandiza kukalamba ndikukonzanso kuwonongeka kwa khungu komwe kulipo. Imalepheretsa kuwonongeka isanachitike ngakhale pang'ono polepheretsa zopitilira muyeso zaulere. Zimathandizanso kumanganso khungu lanu polimbikitsa kupanga collagen, puloteni yomwe imapanga khungu lanu lolumikizana ndikupatsa khungu lanu kapangidwe kake, "akutero Lorschter.

5. Alfa hydroxy acids (AHAs)

“Alpha hydroxy acids ingathandize kuchepetsa kuchuluka kwa magazi. Ndikulimbikitsidwa kuti muzigwiritsa ntchito madzulo, ndikuziteteza ku dzuwa m'mawa, "akutero Lortscher.

“Yambani kamodzi sabata iliyonse, pang'onopang'ono ndikuchulukitsa kuchuluka komwe kumaloledwa. Ma AHA omwe amagwiritsidwa ntchito kwambiri ndi glycolic acid (yotengedwa nzimbe), lactic acid (yotengedwa mkaka), ndi mandelic acid (yotengedwa ndi amondi owawa). ”

3. Yang'anirani zosakaniza mu khungu lanu

Ngati mukumenyanabe malo amdima atsopano, mudzafunikanso kuwunika mosamala khungu lanu. Kusintha uku kumatha kukhala milungu ingapo kapena miyezi. Amatchedwa hyperpigmentation pambuyo potupa ndipo amayamba chifukwa chovulala pakhungu, monga kudula, kuwotcha, kapena psoriasis, koma ziphuphu ndizomwe zimafala kwambiri.

Samalani kwambiri ngati mukufuna kugwiritsa ntchito:

• Mankhwala opatsirana. Izi zimaphatikizapo glycolic acid ndi retinoids.
• Mankhwala akumwa amlomo. Doxycycline ndi isotretinoin (Accutane) zimatha "kukometsa dzuwa ndikuchenjeza za kuwonekera kwa dzuwa," akutero a Lortscher.

Ngakhale dzuwa limathanso kudzetsa kutentha kwawokha palokha, kuwonjezeredwa kwa dzuwa kumathanso kudetsa mawanga. Nthawi zonse onetsetsani zosakaniza za zinthu zatsopano kuti muwone ngati pali zosakaniza zomwe zingayambitse chidwi cha photosensitivity.

Nthawi yomwe muyenera kugwiritsa ntchito mankhwala anu

Takuphimba. Choyamba ziribe kanthu zomwe mumagwiritsa ntchito, tetezani khungu lanu ndi zotchingira dzuwa tsiku lililonse.

1. Kodi muyenera kupeŵa kugwiritsa ntchito zithunziensitizing dzuwa likadawala?

Malinga ndi Lortscher, ayi.

Ngakhale, kuwagwiritsa ntchito usiku ndichizolowezi chabwino (popeza zosakaniza zina zimatha "kunyoza pambuyo pounikira kapena kuwala kwa dzuwa"), kugwiritsa ntchito zomwe mumapanga usiku sikunganyalanyaze mawonekedwe awo a photosensitivity m'mawa.

2. Ndi zinthu ziti zomwe zimapanga (ndipo sizikukuyikani) zomwe zimayika pachiwopsezo chachikulu?

Zotsatira za Vitamini A (retinol, tretinoin, isotretinoin) ndi (glycolic acid, lactic acid, mandelic acid) chitani onjezani chidwi chanu padzuwa. Onetsetsani kuti mumawagwiritsa ntchito usiku ndipo nthawi zonse muzitsatira zotchingira dzuwa tsiku lililonse.

Vitamini C, azelaic acid, ndi beta hydroxy acids (salicylic acid) osatero onjezani chidwi chanu padzuwa. Amatha kugwiritsidwa ntchito masana koma kumbukirani kuti atha kuthandiza kukhetsa akufa, khungu lakhungu lanu, kuwonetsa khungu losalala komanso losalimba pansi.

Chifukwa chiyani kuli kofunika kwambiri kuletsa kuwala kwa dzuwa

Takuyamikirani Bwanji kuti mudziteteze, koma theka la nkhondo yokhala tcheru ndi zochita zanu ndikumvetsetsa bwanji.

Kuwonongeka kwa dzuwa sikungokhala kwa mabala owoneka, mawanga, ndi zizindikilo za ukalamba - Lorstcher akuchenjeza kuti cheza chimayambitsa khansa. "Amaletsanso ntchito zina zoteteza chitetezo cha mthupi, zomwe zimathandiza kwambiri pakukula kwa khansa yapakhungu."

Inde, UVA ndi UVB onse ndi khansa yamagulu, ndipo akugwira ntchito mbali zonse kuti izi zichitike. Ngakhale UVB ikuwotcha khungu lanu, UVA imalowa mkatikati mwa khungu lanu popanda zizindikiritso zomwe zingachitike.

Zowonongeka pakhungu zoyambitsidwa ndi cheza cha UVA:

• kugwetsa
• makwinya
• kutayika kwa khungu
• khungu lowonda komanso lowala kwambiri
• ma capillaries osweka
• chiwindi kapena mawanga azaka
• youma, yaukali, khungu lachikopa
• Khansa yapakhungu

Kuphatikiza apo, pamakhala zowononga pamiyeso: Mwayi wake, mwamvapo za zopitilira muyeso zaulere (komanso kufunikira kwa ma antioxidants) koma anthu ambiri sadziwa kuti radiation ya UVA imapanga izi zowonongera zaulere izi. Izi zikutanthauza kuti khungu lofufutidwa ndilosiyana ndi khungu labwino - ndi khungu lovulala. Ndi chizindikiro kuti thupi lanu likuyesera kuteteza ku kuwonongeka kwina kwa DNA.

"Kuwonetsedwa kwa UVA kwanthawi yayitali kumawononga ulusi wa collagen mu [khungu]," akutero Lortscher. “Sizingokhala masiku ataliatali pagombe zomwe zimayambitsa ukalamba wowonekera. UVA imachitika nthawi zonse mukamapita pagalimoto, kugwira ntchito panja masiku akuda, kapena ngakhale kukhala pafupi ndi zenera. ”

Chifukwa chake muli nacho - mutha kusintha kuwonongeka kwa dzuwa ndi zinthu zonse zothandizidwa ndi sayansi zomwe zilipo, koma monga Lortscher anenera: "[Ngati] simukuteteza [padzuwa], ndiye kuti simukufunika kufunafuna zinthu samalani ndi zaka zakubadwa ndi mitundu ina ya kupatsirana mokwanira, chifukwa mukumenya nkhondo yoti muchepetse! ”

Kate M. Watts ndi wokonda sayansi komanso wolemba zokongola yemwe amalakalaka kumaliza khofi wake usanazime. Nyumba yake yadzazidwa ndi mabuku akale komanso zomangira nyumba, ndipo wavomera moyo wake wabwino kwambiri umabwera ndi patina wabwino wa tsitsi lagalu. Mutha kumupeza pa Twitter.
