Pofuna kuteteza khungu, anthu ambiri amangodziwa za chitetezo cha dzuwa, hydration kapena mankhwala osamalira khungu.Ndipotu, pali nkhani zina zambiri zomwe ziyenera kutsatiridwa.
Choyamba, tiyenera kudziwa chimene chikuwononga khungu lathu.Pali mfundo zingapo zofunika:
Free radical
AGEs advanced glycation end products
Kutaya kwa collagen
Kutupa
Makwinya
1. Mitundu ya makwinya
Makwinya amatha kugawidwa m'mitundu 4 yoyambira kutengera zomwe zidachitika:
Makwinya: Makwinya omwe amayamba chifukwa cha kukalamba kwachilengedwe kwa khungu
Makwinya a actinic: Makwinya obwera chifukwa chopsa ndi dzuwa
Makwinya amphamvu: makwinya obwera chifukwa cha mawonekedwe a nkhope
Makwinya okoka: Makwinya obwera chifukwa cha mphamvu yokoka
Pali zifukwa zambiri za makwinya, monga kutuluka kwa dzuwa, chibadwa, kusowa kwa estrogen, ntchito yosasinthasintha ndi kupuma, zakudya zopanda thanzi, kusuta ndi kumwa, kuwononga chilengedwe, ndi zina zotero, zomwe zingagawidwe m'zinthu zamkati ndi zinthu zakunja.
2. Kupewa makwinya
A. Zomwe tingachite
Kukhala ndi zizolowezi zabwino za moyo ndi kudya kudzabweretsa zotsatira zazikulu komanso zokhalitsa.
Zochita zolimbitsa thupi moyenera komanso kutambasula sizingangowonjezera kulimbitsa thupi, komanso kuchedwetsa mapangidwe a makwinya, makamaka makwinya amphamvu ndi makwinya okoka.
Idyani zakudya zambiri ndi antioxidant (vitamini C, vitamini E, selenium, carotene, lycopene, coenzyme Q10), monga tomato yokazinga (lycopene), blueberries, mphesa, soya, tiyi wobiriwira, ndi zina zotero.
B. Zomwe mankhwala osamalira khungu angachite
Kukana ku radiation ya UV (chitetezo cha dzuwa)
Amateteza chitetezo chamthupi (wonyowa)
Antioxidant (kuchotsa ma free radicals ochulukirapo)
Kulimbikitsa kuchuluka kwa ma cell ndi metabolism (exfoliation)
Antioxidant
1. Antioxidant woimira zosakaniza: astaxanthin, fullerene, vitamini C, vitamini E, selenium ndi mankhwala ake, coenzyme Q, lycopene.
2. Mfundo ya anti-oxidation: chotsani zowonjezera zowonjezera zaulere, imodzi mwa ntchito za free radicals ndiyo kuyambitsa zinthu zolembera (monga AP-1 ndi NF-κB) kuti muwonjezere mawu a matrix metalloproteinases (MMP), imodzi mwa yomwe ndi collagen Enzymes, imatha kupanga kolajeni pang'onopang'ono kutaya katundu wake wapachiyambi, ndipo khungu limataya kusungunuka kwake ndi makwinya ndi sags.
3. Ma antioxidants wamba
▍Vitamini C
Vitamini C ndiye chinthu chodziwika bwino cha antioxidant, chomwe chimakhala ndi anti-oxidation, anti-wrinkle, whitening ndi zina zotsutsana ndi zotupa.Thupi laumunthu limadalira chakudya chachilendo cha kudya kwa vitamini C, koma kwenikweni palibe vuto la kusowa kwa vitamini C.Pakalipano amakhulupirira kuti vitamini C wam'kamwa sichimawonjezera zomwe zili m'maselo a khungu, kotero ngati mukufuna kugwira ntchito pakhungu, muyenera kuyamba ndi mankhwala apakhungu.
▍Vitamini E
Antioxidant yodziwika bwino kwambiri yamafuta ndi vitamini E, koma momwe vitamini E amagwirira ntchito kwambiri ndikugwira ntchito mogwirizana ndi vitamini C kuti awonjezere mphamvu ya antioxidant.
4. Zina
Panganinso matrix akunja kwa khungu
Matrix a extracellular (ECM) a dermis ali ndi zigawo zambiri za mapuloteni: mapuloteni apangidwe (collagen, elastin) ndi mapuloteni omatira (fibronectin, laminin).Kutsika kwa zomwe zili ndi khalidwe la ECM ndi chinthu chofunika kwambiri pa ukalamba wa khungu, kotero kumanganso ECM ndi njira.Oral collagen ndi opanda pake, osagwira ntchito ngati collagen peptides, rhodiola, ginseng ndi zina zowonjezera, zimatha kulimbikitsa magawano a fibroblast ndikulimbikitsa kaphatikizidwe kawo ndi katulutsidwe ka kolajeni.
