Ndi zodzola zachilengedwe, zobiriwira, zathanzi komanso zotetezeka zokhala ndi zomera zokopa kwambiri, zomwe zimapangitsa kuti zinthu ziziwayendera bwino kwambiri. Kukhazikitsanso zinthu zomera sikumangobwezeretsa mbiriyakale, koma kuchirikiza chikhalidwe cha Chinese, kuphatikiza zikhalidwe zachikhalidwe zaku China, ndikugwiritsa ntchito ukadaulo wamakono wazomera zatsopano, kuti apange sayansi ndi zotetezeka zodzikongoletsera zachilengedwe. Zogulitsa zamankhwala zimapereka zida zobiriwira. Kuphatikiza apo, zobzala zomera zimagwiritsidwa ntchito kwambiri ngati mankhwala, zowonjezera zowonjezera zakudya, zakudya zogwira ntchito, zakumwa, zodzola, zodzoladzola ndi minda ina.
Zomera zapeza. Zodzikongoletsera zopangidwa ndi zomera zopanga monga zothandizira zimakhala ndi zabwino zambiri zomwe zikufanizira ndi zopeka zachikhalidwe zomwe zimadalira pa mankhwala, kupangitsa kuti malonda akhale otetezeka; Zolengedwa zachilengedwe zimatengeka mosavuta ndi khungu, kupangitsa kuti malonda azigwira bwino ntchitoyi ndi ofunika kwambiri; Ntchitoyi ndiyotchuka kwambiri, etc.
Kusankha chomera cholondola ndikuwonjezera kuchuluka kwa mbewu zopangira zinthu zodzikongoletsera kungakulitse zotsatira zake. Ntchito zazikuluzikulu za zomera zodzola zodzikongoletsera ndi: kutenthedwa, kuwonongeka, kuteteza dzuwa, antiseptic, ndi obzala ndi obiriwira.
MZotsatira zoyipa
Zopangira zodzikongoletsera zodzikongoletsera zimachitika makamaka m'njira ziwiri: wina amapezeka ndi zotsekemera zamadzi zopangira ma hydrogen pakati pa othandizika ndi mamolekyulu amadzi; Chinacho ndichakuti mafuta amapanga filimu yotsekedwa pakhungu.
Omwe amatchedwa kuti kuwononga zodzikongoletsera ndi zodzikongoletsera zomwe zimakhala ndi chonyowa zopanga kuti zikhale chinyezi chokhala ndi chinyontho chosungirako chinyezi cha stratum ndi kutukwana kwa khungu. Kuchita zonunkhira kumagawika mitundu iwiri malinga ndi mawonekedwe ake: imodzi ndikugwiritsa ntchito zinthu zosunga madzi zomwe zitha kuphatikizidwa mwamphamvu ndi chinyezi chonyowa chivundikiro, monga glycerin; Chinacho ndi chinthu chomwe chiri chopanda m'madzi, chotupa cha filimu yopangidwa pansi pakhungu, lomwe limachita ngati chisindikizo chopewa kuwonongeka kwa madzi, kotero kuti ma barneum stratum amakhala ndi chinyezi kapena Zowongolera, monga Perolatim, mafuta, ndi ma sex.
Pali zomera zingapo zomera zomwe zimapangitsa kuti pakhale manyowa komanso zonyowa, monga alomi cera, ogwedezeka, a maolimali, etc., onse ali ndi mphamvu yophuka.
Zotsatira zotsutsa
Ndi kuchuluka kwa zaka, khungu limayamba kuwonetsa kukalamba, komwe kumaphatikizapo kuchepetsa collagen, Elastin, Mucopolysaccharide ndi zina zomwe zimapezeka pakhungu lam'khungu, zotupa zamagazi Khoma limachepa, ndipo khungu la khungu limaphimba pang'onopang'ono. Kuchepetsa, kuchepetsa mafuta kwambiri, ndipo mawonekedwe a makwinya, chloasma ndi mabwalo azaka.
Pakadali pano, maphunziro am'mbuyomu pazomwe zimayambitsa ukalamba zafotokozetsa mwachidule izi:
Chimodzi ndi chiwonjezeko ndi ukalamba waulere. Maulesi aulere ndi maatomu kapena mamolekyulu okhala ndi ma elekitoni osaphunzira omwe amapangidwa ndi homolysis of Covale. Amakhala ndi kuchuluka kwa zochita za mankhwala ndipo ayang'aniridwa peroxidation yokhala ndi lipids osavomerezeka. Lipid peroxide (LPO), ndipo mankhwala ake omaliza, Aljalddehyde (MDA), angatani mu maselo ambiri mu maselo amoyo, kuwonongeka kwa mamolekyulu a DNA, ndi kusokonezeka kwa maselo kapena kusokonezeka kwa maselo kapena kusokonezeka kwa maselo kapena kusokonezeka kwa maselo kapena kusokonezeka kwa maselo kapena kusokonezeka kwa maselo kapena kusokonezeka kwa maselo kapena kusokonezeka kwa maselo kapena kusokonezeka kwa maselo kapena kusokonezeka kwa maselo kapena kusokonezeka kwa maselo kapena kusokonezeka kwa maselo kapena kusokonekera kwa maselo kapena kusokonezeka kwa maselo kapena kusokonezeka kwa maselo.
Chachiwiri, UVB ndi UVA mu kuwala kwa dzuwa kumatha kuyambitsa kusovuka. Makina a ultraviolet makamaka amayambitsa kukalamba kudzera pamachitidwe otsatirawa: 1) kuwonongeka kwa DNA; 2) Kulumikizana kwa collagen; 3) Kuchepetsa kwa kuyankha kwa mthupi pokopa njira yothandizira kulembetsa; 4) Mbadwo wa ma radicals opindulitsa kwambiri amalumikizana ndi zida zamkati zosiyanasiyana. Kuphatikiza apo, osakhala Enzymatic glycosyty, kusokonezeka kagayidwe kachakudya, ndi matrix metallophrotenase kukalamba kumakhudzanso kukalamba.
Zomera zobzala monga elastasta inhibitors zaposachedwa m'zaka zaposachedwa, monga screen, morinda, shuihea, alvia, Alvica ndi zina zambiri. Zotsatira za phunziroli zikuwonetsa kuti: Salvia Miltiorrhazataza (esm) imatha kukweza mawonekedwe a filagracy mosadziwika bwino ndi khungu la edgermal, ndipo amatenga gawo pokana ukalamba komanso monyozeka ; Kuchokera pazinthu zotsatsa zimatulutsa DPPARD DPHh DPPH, ndikugwiritsa ntchito zinthu zoyenera zodzikongoletsera, zomwe zimabweretsa zabwino; Polygonum Cuspidatum Tingafirit ali ndi mphamvu inayake pa emalastase, potero odana ndi ukalamba ndi anti-khwinya.
Fkusufupi
Kusiyana kwa khungu la thupi nthawi zambiri kumadalira zomwe zili ndi kufalitsa kwa epidermal melanin, magazi omwe amafalikira kwa magazi, ndi makulidwe a mitengo ya stratum. Kuda khungu kapena mapangidwe amdima amakhudzidwa ndi kudzikundikira kwa melanin ambiri, oxidation khungu, keratino poizoni yakuwala, ndikudzikundikira kwa poizoni mthupi.
Masiku ano, zotsatira za kuchotsedwa kwa Fly Fyvagval kumatheka makamaka pakukhudza mapangidwe ndi kuchuluka kwa melanin. Limodzi ndi tressinase inrobetor. Potembenuka kuchokera ku tyrosine ku Dopa ndi Dopa ku Dopaquinone, onsewa ndi omwe amagwira ntchito ndi Tylasinase, omwe amawongolera makonzedwe a melanis, ndipo amawona ngati njira yotsatira itha.
Pamene zinthu zosiyanasiyana zimachita ku Tersunase kuti muwonjezere ntchito yake, melanin synthesis ikuchulukirachulukira, ndipo ntchito ya temmandase italetsa, ma melalanin synthesis amachepetsa. Maphunziro awonetsa kuti Arbutin amatha kuletsa ntchito ya tressinase mu zoopsa popanda Melanocyte zoopsa, bweretsani kapangidwe ka Dopa, ndipo motero zimalepheretsa kupanga melanin. Ofufuzawo adaphunzira ma Cunitoni a mankhwala ku Black Arhizomes ndi zotsatira zawo zoyera, pomwe zimapangitsa khungu kukwiya.
Zotsatira zofufuzira zikuwonetsa kuti: Pakati pa mitundu ya 17 yomwe ilipo (HLH-1 ~ 17) imatha kulepheretsa mapangidwe a melanin, ndipo zomwe zimapangitsa kuti zisagwedezeke pakhungu. Ren Hongrong et al. atsimikizira kudzera poyesa kuti mafuta onunkhira a lottas atachoka ali ndi mphamvu yothandiza pakupanga melanin. Monga mtundu watsopano wa wothandizila chomera chomera, amatha kuphatikizidwa ndi kirimu woyenera ndipo ukhoza kupangidwa pakhungu, chisamaliro cha khungu komanso chiwonetsero. Zodzikongoletsera.
Palinso nthumwi ya ma cytotocyte cytotoxic, monga a Endothelin obwera chifukwa cha zobzala, zomwe zimatha kupatsa ulemu kwa Ilanotyte ku Melanocyte Membrane kupanga. Kudzera mwa kuyesa kwa cell, Frédéric Bonté et al. Anawonetsa kuti mtundu watsopano wa brassatttya ukhoza kuletsa kuchuluka kwa Melanoction. Kuwonjezera zodzikongoletsera zoyenera zodzikongoletsera zili ndi zotsatira zowoneka bwino pakhungu ndikuwala. Zhang mul. obwezedwa ndikuphunzira zitsamba zaku China monga scringlutia Baicalensis, polygonum Cuspidatum ndi burnet, ndipo zotsatira zake zidalepheretsa kuti ma cell a intracellur and insuraces, kuti akwaniritse zotsatira za zoyera.
kutetezedwa kwa dzuwa
Nthawi zambiri, nthawi zambiri zopangidwa ndi dzuwa zodzikongoletsera zimagawidwa m'magulu awiri: imodzi ndi uV onyamula ma uv, omwe ali mapangidwe opanga, monga ma ketone; Wina ndi othandizira otetemera, ndiye kuti, dzuwa limatulutsa ma sunscreans, monga Tii2, Zno. Koma mitundu iwiri ya matope imatha kuyambitsa khungu, khungu lakhungu, komanso polotakhoda. Komabe, mbewu zambiri zachilengedwe zimakhala ndi njira yabwino kwambiri yopangira ma rays, ndipo limbikitsani ntchito yolimbitsa thupi pochepetsa kuwonongeka kwa radiation komwe kumachitika pakhungu.
Kuphatikiza apo, zosakaniza ndi dzuwa mu zobzala zobzala zimakhala ndi maubwino osakwiya pakhungu, kukhazikika kofananira, chitetezo komanso kudalirika kwa mankhwala amtundu wa mankhwala ndi mafano. Zheng Hongyan et al. Zovala zitatu zachilengedwe zimapanga, CORTEX, yokhazikika ndi Arbutin, ndipo adaphunzira chitetezo cha chitetezo ndi UVB ndi UVA. Zotsatira zofufuzira zikuwonetsa kuti: Zomera zina zachilengedwe zimawonetsa zabwino za UV. Kuwongolera ndi ena adagwiritsa ntchito tartery Buckwheat flavonoids ngati zida zopangira kuti muphunzire kununkhira kwa ma flavonoids. Kafukufukuyu adawona kuti kugwiritsa ntchito flavonoids ku emulsions kwenikweni ndikuphatikiza ndi ma sunsnerens apathupi ndi mankhwalawa kumapereka maziko a chomera dzuwa muzodzola mtsogolo.
