Ngakhale pali zoopsa, kuyeretsa khungu kumatchuka kwambiri kuposa kale

Kuyera kapena kuyeretsa ndi nkhani yotsutsana kwambiri. Imakhala ndi njira zokongoletsera mawonekedwe anu.
Pali njira zambiri zopangira khungu kuwalira. Izi zimaphatikizapo mafuta apakhungu apadera ndi mankhwala a laser. Chifukwa cha mtengo wake wotsika komanso chitetezo chokwanira, anthu ambiri amasankha mafuta akhungu.
Ngati mukuganiza zopanga zoyera, pali zinthu zina zomwe muyenera kudziwa kaye. Nkhaniyi ikufotokoza zinthu zofunika kwambiri, makamaka zosakaniza.莫诺苯宗
Kuwunikira khungu kumatanthauza kugwiritsa ntchito mankhwala apadera kapena zinthu zina kuti khungu kapena khungu lichepe. Anthu amagwiritsa ntchito mawu osiyanasiyana kuti afotokoze, kuphatikiza kuyeretsa, kuyeretsa kapena kuyeretsa khungu.
Kuwonetsedwa kwa khungu la munthu pazinthu zambiri kumatha kuyipangitsa kukhala kuzimiririka. Kukalamba, zowononga, fumbi, dothi, kuwala kwa ultraviolet ndi mankhwala (kuphatikizapo omwe ali muzinthu zosamalira khungu) zitha kuwononga khungu.
Kuperewera kwa zakudya m'thupi, kusankha njira zosayenera pamoyo ndi kupsinjika kungakhalenso ndi vuto pakhungu.
Zinthu zosiyanasiyana izi zimatha kubweretsa mavuto osiyanasiyana, kuphatikiza mdima, mawanga azaka, zipsera zamabala ndi mabala.
Anthu amadalira pazinthu zoyera komanso zochizira kuti athetse mavutowa. Amagwiritsa ntchito kukonza kapena kubwezeretsa khungu.
Ndi zinthu zowunikira khungu, mutha kufananitsa madera akhungu ndi khungu loyandikana nalo. Maderawa ndi monga mabala obadwa nawo, timadontho tating'onoting'ono, chloasma ndi matani.
Kuunikira khungu ndichinthu chodabwitsa padziko lonse lapansi, ngakhale akuti pali chidwi chachikulu pakuwala khungu ku Africa, Middle East ndi India. Pofika chaka cha 2013, zikuyembekezeredwa kuti pofika chaka cha 2018, msika wogulitsa khungu lonse udzafika pafupifupi madola 20 biliyoni aku US.
Zogulitsa ndi njira zamankhwala zitha kugwiritsa ntchito njira zosiyanasiyana kuti zilimbikitse mawonekedwe owoneka bwino komanso owoneka bwino. Koma zowala makamaka zimagwira ntchito polepheretsa kupanga melanin kapena kuthandiza kuwononga.
Melanin ndiye chinthu chofunikira kwambiri pakhungu. Ichi ndi mtundu wa polima wakuda. Pali anthu ambiri omwe ali ndi khungu lakuda.
Thupi la munthu limatulutsa pigment iyi popanga melanin. Asayansi apeza mitundu iwiri yayikulu ya mankhwalawa pakhungu ndi tsitsi, omwe ndi: Eumelanin (wakuda kapena wabulauni) ndi pheomelanin (wachikaso kapena wofiira). Mtundu wa khungu umadziwika ndi kamvekedwe kake.
Zowala zambiri zimagwira ntchito poletsa kupanga mitundu ya inki. Amachita izi pochepetsa zochitika za michere ina yomwe imathandizira pantchitoyi. Enzyme yodziwika bwino m'kati mwake ndi tyrosinase.
Thupi lanu limadalira L-tyrosine kuti apange melanin. Mu gawo loyamba la kupanga melanin, tyrosinase amasintha amino acid kukhala L-Dopa. Brighteners amayesetsa kuletsa mawonekedwe, kutsegula kapena zochitika za michere, potero zimalepheretsa kupanga mitundu ya inki.
Zina mwazinthu zopangira zoyera zitha kuthandizira kutsitsa. Amathandizira kuwononga melanin yomwe ili kale mthupi.
Anthu ambiri amasankha zinthu zoyera pakhungu chifukwa samakhutira ndi zodzoladzola kuti zifanane ndi khungu lawo. Ngakhale atakwanitsa kutero, nthawi zambiri amawopa kulandira chithandizo cha laser.
Komabe, zinthu zomwe zimayesetsa kukwaniritsa mawonekedwe owoneka bwino nthawi zambiri zimavutika ndi rap yoipa. Malinga ndi malipoti, amayambitsa mavuto ena osiyanasiyana omwe angawapangitse kukhala osayenera kugwiritsa ntchito konse.
Zimanenedwa kuti zambiri mwazinthuzi zimakhala ndi zinthu zosavulaza. Nthawi zina, amapezeka kuti ali ndi mankhwala oopsa omwe angayambitse mavuto a khungu, kuphatikizapo khansa.
Anthu nthawi zambiri amagwiritsa ntchito mawu oti "kuyeretsa" pokambirana za chitetezo ichi. Pachifukwa ichi, makampani nthawi zambiri amapewa kugwiritsa ntchito kufotokozera zomwe amapanga.
Kugwiritsa ntchito zinthu zovulaza pazaka zapitazi kwapangitsa kuti mafuta azitsuka aziletsedwa m'maiko ena.
Sitikumvetsetsa chifukwa chomwe opanga ena amasankhira mankhwala owopsawa. Poganizira zakupezeka kwa njira zina zachitetezo kapena zachilengedwe. Mwina izi zitha kukhala chifukwa chofunafuna phindu lochulukirapo.
Pansipa tikambirana zinthu zina zowopsa, mukazizindikira, nthawi yomweyo muyenera kuyika kirimu choyera. Mupezanso zidziwitso pazotetezedwa zomwe mankhwala abwino ayenera kukhala nawo.
Ichi ndi chinthu chotchuka kwambiri chomwe opanga nthawi zambiri amaphatikiza maphikidwe. Tsopano, anthu ochulukirachulukira akudziwa kuwopsa kwake, zomwe zapangitsa kuti makampani ena agwiritse ntchito malongosoledwe anzeru a izi, monga mercury, mercuric ammonia kapena mercury chloride.
Mercury yakhala ikugwiritsidwa ntchito poyeretsa khungu kwazaka zambiri. Ikagwiritsidwa ntchito pakhungu, imatha kuchepetsa kaphatikizidwe ka melanin, chifukwa chake imayamikiridwa kwambiri. Pofuna kuchepetsa mtengo wogulitsa wopanga, mtengo wake ndi wotsika komanso wosavuta kupeza.
Kuyambira pamenepo, mayiko / zigawo zambiri (koyambirira kwa ma 1970 ku Europe) zaletsa kugwiritsa ntchito mankhwalawa kuyeretsa khungu. Mankhwalawa ndi oletsedwa ndipo amadziwika ngati poizoni ku United States.
Mercury imatha kukhala pakhungu kwa nthawi yayitali, chifukwa imatha kubweretsa mavuto ena. Zimatha kuyambitsa khungu komanso mabala osafunikira. Palinso malipoti omwe amakhudza kugwira ntchito kwa ubongo ndipo amawononga impso. Akamagwiritsidwa ntchito ndi amayi apakati kapena amayi oyamwitsa, amathanso kuyambitsa matenda am'mimba mwa ana
Ichi ndi chimodzi mwazida zowunikira khungu zomwe zimathandizira kutsitsa. Kawirikawiri amalimbikitsidwa kuti anthu omwe ali ndi vitiligo amakonda kugwiritsa ntchito mafuta opaka mafuta kapena benzophenone. Matendawa amadziwika ndi kuwala komanso mdima pakhungu. Pawiriyu amathandizira kuchepetsa pigment pakhungu ndikupangitsa khungu kukhala lolingana.
Koma imatha kuwononga ma melanocyte ndikupanga ma melanosomes ofunikira kaphatikizidwe ka melanin. Chifukwa chake, kuigwiritsa ntchito kumatha kuyambitsa kusintha kosatha kapena kosasinthika.
Kupatula vitiligo, madokotala samalimbikitsa kugwiritsa ntchito monobenzophenone pansi pazinthu zina zilizonse. Koma mudzadabwa kupeza kuti makampani ena amaphatikizamo zodzikongoletsera wamba. Mavuto omwe amabwera chifukwa chogwiritsa ntchito mankhwalawa akuphatikizira mtundu wosiyanasiyananso mitundu ndi kuzindikira dzuwa.
Zosakaniza zowunikira khungu ndizosokoneza, kuti kugwiritsa ntchito kwanu kungakhale ndi zotsatira zosayembekezereka kwa ena. Amati ikagwiritsidwa ntchito, imatha kupangitsa ena kusintha khungu.
Kodi mukudabwa? Mwina simunadziwe kale kuti ma steroids atha kupezeka pazinthu zoyera. Koma angathe.
Steroids itha kuthandiza kuyeretsa khungu m'njira zosiyanasiyana. Chimodzi mwazomwezi chimakhudzana ndi momwe amachepetsera ntchito ya ma melanocytes. Koma amathanso kuchepetsa chiwongola dzanja cha khungu.
Komabe, ndilo vuto lalikulu kuti zinthu zotsutsanazi sizinaphatikizidwe ndi zonona zoyera. Eczema ndi psoriasis ndi matenda awiri omwe ma dermatologists amagwiritsa ntchito pochiza. Vuto lenileni limakhala kugwiritsa ntchito nthawi yayitali.
Steroids, kuphatikiza ma corticosteroids, amagwiritsidwa ntchito makamaka pochiza matenda otupa pakhungu. Muyeneranso kupatsidwa mankhwala, zomwe zikutanthauza kuti simukuyenera kuwapeza mu zodzoladzola wamba. Kugwiritsa ntchito kwa nthawi yayitali kumatha kuchepetsa kuwonongeka kwamuyaya pakhungu.
Zinthu zambiri zosamalira khungu zimakhala ndi mafuta amchere monga chopangira. Wopanga amagwiritsa ntchito kuti athandizire khungu. Ndiotsika mtengo-wotsika mtengo kuposa mafuta achilengedwe.
Komabe, anthu akhala akuda nkhawa za kuthekera kwa izi popangitsa mavuto pakhungu. Mafuta amchere amatha kutseka khungu lanu, zomwe zimapangitsa kuti zikhale zovuta kuchotsa zinthu zoyipa. Chifukwa chake, mutha kukumana ndi mavuto monga ziphuphu ndi ziphuphu. Zowonjezerapo, chophatikizacho chimaganiziridwa kuti ndi cha khansa.
Simukuyenera kupeza zabwino zowunikira khungu kuchokera apa. Parabens ndi gulu la zotetezera. Opanga amawagwiritsa ntchito makamaka kukulitsa moyo wa alumali wazodzola.
Mavuto omwe izi zimatha kuyambitsa zimasokoneza makina anu endocrine ndi ziwalo zoberekera. Zapezeka kuti zikuwonjezera chiopsezo cha khansa.
Apa, muli ndi zosakaniza zotchuka kwambiri pazinthu zosamalira khungu. Hydroquinone ndi mankhwala omwe amaletsa kaphatikizidwe ka melanin poletsa tyrosinase. Izi ndizothandiza kwambiri. Chifukwa chake, imapezeka mumafuta ambiri oyeretsa.
Izi sizowopsa ngati zinthu zina zoyipa. Izi ndichifukwa choti akatswiri nthawi zina amalimbikitsa, makamaka mtundu wa 2% (kapena wotsika). Koma mungadziwe bwanji mphamvu ya mafuta oyera, makamaka ngati sananenedwe?
Kuwonjezera mphamvu, ntchito yaitali hydroquinone komanso kumaonjezera ngozi ya mavuto. Zitha kupangitsa kuti khungu lisinthe, pomwe limakhala lamuyaya. Izi zitha kusokonezeranso ma enzyme ena omwe amatenga gawo lalikulu mthupi la munthu.
Mowa, dioxane ndi phthalates ndizinthu zina zomwe zingakhale zowopsa zomwe muyenera kuzimvera pakhungu lanu lowala khungu kuti muteteze malo amdima.
Mukamayankhula zachilengedwe, zowala zowala pakhungu, mndandandawu sukhala wathunthu ngati suphatikiza zipatso za zipatso (monga malalanje ndi mandimu). Izi ndizopindulitsa, makamaka chifukwa cha kuchuluka kwa vitamini C. Amakhulupirira kuti kampaniyi imakhala ndi zinthu zoyera pakhungu.
Komabe, ndizofala kwambiri kuti anthu amalankhula za vitamini C kwambiri malinga ndi phindu la khungu. Pawiriyo imakhala ndi zida za antioxidant ndipo imatha kuteteza zizindikiro za ukalamba, monga mizere yabwino ndi makwinya.
Kuchokera ku zipatso za zipatso kumakhulupiliranso kuti kumathandizira kupanga collagen, chomwe ndichinsinsi chachikopa cholimba, chachinyamata. Amatha kukonza mawonekedwe akhungu ndikulimbikitsa kukula kwa maselo atsopano.
Zosakaniza izi zimatchedwanso vitamini B3 ndipo nthawi zambiri zimapezeka muzinthu zabwino kwambiri zosamalira khungu. Chimodzi mwa zifukwa za izi ndi khungu lowala khungu. Zimathandiza kuchepetsa kupanga melanin.
Nicotinamide imatulutsa zotsatira za antioxidant ndipo imakhala ndi zotsutsana ndi zotupa. Mudzawona kuti amasunga chinyezi ndipo amathandizira kupangitsa khungu kukhala losalala komanso lofewa. Mavitamini amathandizanso kuwongolera khungu kukhala mafuta.
Pogwiritsidwa ntchito ndi N-acetylglucosamine, mphamvu ya vitamini iyi imakhulupirira kuti imakulitsidwa.
Mwina mwamvapo kuti anthu ena amalimbikitsa kugwiritsa ntchito zipatso (monga mabulosi, mabulosi abulu kapena mabulosi abulu) kuti khungu lanu likhale loyera. Izi ndichifukwa chakupezeka kwa kampani yotchedwa arbutin, yotchedwanso hydroquinone-β-D-glucoside.
Arbutin amathandiza kuchepetsa kupanga melanin m'thupi. Ili ndi ma isomers awiri: α ndi β. Alpha isomer ndiyokhazikika komanso yoyenera kuwunikira khungu.
Zosakaniza zachilengedwe izi zimawerengedwa kuti ndi njira ina yotetezeka m'malo mwazinthu zodziwika bwino pazinthu zambiri. Pamene tyrosinase iyenera kuletsedwa, mawonekedwe oyerawo ndiwothandiza kwambiri.
Sizinthu zonse zomwe zili ndi mawu oti "asidi" ndizovulaza. Zambiri mwazinthu izi ndizachilengedwe komanso zopindulitsa. Chifukwa chake musachite mantha.
Azelaic acid ndi gawo la barele ndi mbewu zina, ndipo amagwiritsidwa ntchito kwambiri pochizira ziphuphu ndi rosacea. PH yake imakhala yofanana ndi khungu, motero ndiyotetezeka kwambiri.
Ofufuza apeza kuti izi zimathandizanso kuyeretsa khungu. Kafukufuku wasonyeza kuti ndi njira yothandiza yochizira khungu. Zingathandize kupewa kupanga melanin.
Molekyu ya tripeptide ndi chinthu chodziwika bwino chotsutsana ndi ukalamba chomwe chimateteza khungu ku kuwonongeka kwa okosijeni. Kuunikira khungu ndi chimodzi mwazabwino zomwe zimaphatikizidwa.
Glutathione imatha kupewetsa kuwonongeka kwa dzuwa. Kuyeretsa khungu nthawi zambiri kumachepetsa mphamvu yanu yachilengedwe yoteteza dzuwa. Koma izi zimakhala ndi anti-oxidant ndipo zimatha kukutetezani ku cheza cha UV.
Komabe, akatswiri amati molekyuluyo imagwira bwino ntchito osagwiritsa ntchito kwanuko. Njira imodzi yothetsera vutoli ndi kuligwiritsa ntchito limodzi ndi mankhwala ena (monga vitamini C).
Monga tonse tikudziwa, achi China amagwiritsa ntchito mitundu yosiyanasiyana ya khungu. Kafukufuku wasonyeza kuti zowonjezera kuchokera ku chomera cha licorice, makamaka galapudine, zimatha kuwalitsa khungu.
Katundu ameneyu amakhulupirira kuti amawalitsa khungu m'njira zosiyanasiyana. Koma imagwira ntchito poletsa ntchito ya tyrosinase-mwina mpaka 50%.
Kafukufuku wasonyeza kuti chifukwa imatha kulepheretsa kaphatikizidwe ka melanin, imatha kuyeretsa khungu. Imachita izi poletsa zochitika za tyrosinase.
Crystal ufa ndiwotulutsa wa nayonso mphamvu ya mpunga, womwe uli woyenera kwambiri pakhungu lowonongeka komanso losavuta. Amapezeka nthawi zambiri popanga vinyo waku mpunga waku Japan. Akuti achi Japan akhala akugwiritsa ntchito kwa nthawi yayitali pochiza khungu.
Muyenera kuzindikira kuti ndizosiyana ndi kojic acid dipalmitate yomwe makampani ena amakhala. Ngakhale zosakaniza zina zitha kuthandizanso, sizothandiza ngati kojic acid.
Ichi ndi chimodzi mwaziwiri za alpha hydroxy acids (AHA) zomwe zaphunziridwa kwambiri-zina ndi lactic acid. Chifukwa cha kukula kwa ma molekyulu, amayamikiridwa kwambiri chifukwa chokhoza kulowa pamwamba pachikopa.
Anthu ambiri amadziwa kuti glycolic acid ndiyowonjezera. Zimathandizira kupititsa patsogolo kukonzanso kwama cell ndikuchotsa khungu lopanda thanzi kapena lakufa. Koma izi ndizoposa pamenepo.
Ndi izi, mutha kukhala ndi khungu lowala. Kafukufuku wasonyeza kuti itha kukuthandizani kuti muchepetse kupanga melanin mthupi lanu, potero amalimbikitsa khungu.
Ngakhale kuyeretsa kapena kuyeretsa kumatha kukhala nkhani yotsutsana, si aliyense amene angakwanitse kutero. Anthu omwe ali ndi mavuto akhungu (monga mawanga azaka, mawanga, mdima ndi zikwangwani) sadzawopsezedwa ndi malipoti oyipa okhudza vutoli.
Chowonadi ndi chakuti anthu nthawi zambiri amatsutsa kuyeretsa kwa khungu chifukwa cha kuthekera kwakusokonekera. Kufotokozera kwakukulu kwavutoli ndikuti wopanga amagwiritsa ntchito zinthu zowopsa, mwina kuti apange ndalama. Pamene ogula amadziwitsidwa zambiri, mchitidwe woipawu ukusintha tsopano.
Monga mukuwonera pamwambapa, pali zotetezeka, zosakaniza zachilengedwe zomwe zingapangitse khungu lanu kukhala lowala komanso labwino. Muyenera kuyang'ana zinthu izi pazomwe mukufuna kugula. Musanagule, chonde fufuzani za zinthu zina zomwe sitinatchule pano.
Ma cookie ofunikira ndiofunikira kwambiri kuti tsambalo ligwire ntchito. Gululi limangokhala ndi ma cookie omwe amatsimikizira ntchito zoyambira ndi chitetezo patsamba lino. Ma cookies awa sasunga zambiri zaumwini.
