Pali zomera zingapo muzomera zomwe zimakhala ndi hydrating ndi moisturizing, monga aloe vera, udzu wam'nyanja, azitona, chamomile, ndi zina zotero, zonse zimakhala ndi mphamvu zowonongeka.
Anti-kukalamba zotsatira
Ndi kukula kwa ukalamba, khungu limayamba kusonyeza ukalamba boma, amene makamaka kuchepetsa kolajeni, elastin, mucopolysaccharide ndi zina zili pakhungu ndi madigiri osiyanasiyana, Mitsempha kupereka khungu zakudya atrophy, elasticity wa chotengera cha magazi. khoma amachepetsa, ndi khungu epidermis pang`onopang`ono thins.Kutupa, kuchepa kwamafuta ochepa, komanso mawonekedwe a makwinya, chloasma ndi mawanga azaka.
Pakadali pano, kafukufuku wam'mbuyomu wokhudza zomwe zimayambitsa ukalamba wa anthu afotokoza mwachidule zinthu izi:
Chimodzi ndi kuwonjezeka ndi kukalamba kwa ma free radicals.Ma radicals aulere ndi ma atomu kapena mamolekyu okhala ndi ma elekitironi osalumikizana omwe amapangidwa ndi homolysis ya covalent bond.Iwo ali ndi mlingo wapamwamba wa zochita za mankhwala ndipo adutsa peroxidation ndi unsaturated lipids.Lipid peroxide (LPO), ndi mankhwala ake omaliza, malondialdehyde (MDA), amatha kuchitapo kanthu ndi zinthu zambiri m'maselo amoyo, zomwe zimapangitsa kuchepa kwa biofilm permeability, kuwonongeka kwa mamolekyu a DNA, ndi kufa kwa selo kapena kusintha.
Chachiwiri, kuwala kwa UVB ndi UVA padzuwa kumatha kuyambitsa khungu.Ma radiation a Ultraviolet makamaka amayambitsa kukalamba kwa khungu kudzera m'njira zotsatirazi: 1) kuwonongeka kwa DNA;2) kugwirizanitsa kwa collagen;3) kuchepetsa kuyankhidwa kwa chitetezo cha mthupi mwa kuyambitsa njira yoletsa kuyankha kwa antigen-stimulated;4) m'badwo wa zotakasika kwambiri free ankafuna kusintha zinthu mopitirira kucheza ndi osiyanasiyana okhudza maselo ambiri nyumba 5. Mwachindunji ziletsa ntchito epidermal Langerhans maselo, kuchititsa photoimmunosuppression ndi kufooketsa chitetezo cha m'thupi ntchito pakhungu.Kuphatikiza apo, glycosylation yopanda enzymatic, zovuta za metabolic, ndi ukalamba wa matrix metalloproteinase zidzakhudzanso ukalamba wa khungu.
Zomera zamasamba monga zoletsa zachilengedwe za elastase zakhala nkhani yotentha kwambiri m'zaka zaposachedwa, monga Scutellaria baikalensis, Burnet, Morinda citrifolia mbewu, Moringa, Shuihe, Forsythia, Salvia, Angelica ndi zina zotero.Zotsatira za kafukufukuyu zikuwonetsa kuti: Salvia miltiorrhiza extract (ESM) imatha kulimbikitsa mafotokozedwe a filaggrin mu ma keratinocyte wamba amunthu ndi khungu la AmoRe, lomwe limatha kupititsa patsogolo ntchito ya kusiyanitsa kwa epidermal ndi hydration, ndikuthandizira kukana kukalamba ndi kunyowa. ;kuchokera ku zomera zodyedwa Chotsani anti-free radical DPPH yogwira mtima, ndikuyiyika kuzinthu zodzikongoletsera zoyenera, ndi zotsatira zabwino;Kutulutsa kwa polygonum cuspidatum kumakhala ndi zoletsa zina pa elastase, potero odana ndi ukalamba komanso odana ndi makwinya.
Fsasamala
Kusiyana kwa khungu la thupi la munthu nthawi zambiri kumadalira zomwe zili ndi kugawa kwa epidermal melanin, kufalikira kwa magazi a dermis, ndi makulidwe a stratum corneum.Kudetsedwa kwa khungu kapena kupangika kwa mawanga akuda kumakhudzidwa makamaka ndi kudzikundikira kwa melanin wambiri, okosijeni wa khungu, keratinocyte deposition, khungu losayenda bwino la microcirculation, komanso kudzikundikira kwa poizoni m'thupi.
Masiku ano, zotsatira za kuchotsa freckle zimatheka makamaka pokhudza mapangidwe ndi kuchuluka kwa melanin.Imodzi ndi tyrosinase inhibitor.Pakutembenuka kuchokera ku tyrosine kupita ku dopa ndi dopa kupita ku dopaquinone, onsewa amathandizidwa ndi tyrosinase, yomwe imayang'anira mwachindunji kuyambika ndi liwiro la kaphatikizidwe ka melanin, ndikuzindikira ngati njira zotsatila zitha kupitilira.
Pamene zinthu zosiyanasiyana zochita pa tyrosinase kuonjezera ntchito yake, melanin kaphatikizidwe ukuwonjezeka, ndipo pamene ntchito tyrosinase oletsedwa, melanin synthesis amachepetsa.Kafukufuku wasonyeza kuti arbutin amatha kuletsa ntchito ya tyrosinase m'gulu la ndende popanda poizoni wa melanocyte, kulepheretsa kaphatikizidwe ka dopa, motero kuletsa kupanga melanin.Ofufuza adaphunzira zamagulu amtundu wa tiger wakuda ndi zoyera zawo, ndikuwunika kupsa mtima kwapakhungu.
Zotsatira zafukufuku zimasonyeza kuti: pakati pa 17 yokhayokha (HLH-1～17), HLH-3 ikhoza kulepheretsa mapangidwe a melanin, kuti akwaniritse zotsatira za kuyera, ndipo chotsitsacho chimakhala ndi mkwiyo wochepa kwambiri pakhungu.Ren Hongrong et al.atsimikizira kudzera muzoyesa kuti mafuta onunkhira a lotus mowa amalepheretsa kupanga melanin.Monga mtundu watsopano wa zoyera zomwe zimachokera ku zomera, zimatha kusakanikirana ndi zonona zoyenera ndipo zimatha kupangidwa kukhala chisamaliro cha khungu, anti-kukalamba ndi kuchotsa ma freckle.Zodzoladzola Zogwira Ntchito.
Palinso melanocyte cytotoxic wothandizira, monga endothelin antagonists opezeka zomera akupanga, amene akhoza mpikisano ziletsa kumanga endothelin kwa melanocyte nembanemba zolandilira, ziletsa kusiyanitsa ndi kuchuluka kwa melanocytes, kuti ziletsa Ultraviolet cheza induces cholinga cha melanin. kupanga.Kudzera mu kuyesa kwa ma cell, Frédéric Bonté et al.adawonetsa kuti ma orchid atsopano a Brassocattleya amatha kuletsa kufalikira kwa ma melanocyte.Kuwonjezera pa zodzoladzola zoyenera zimakhala ndi zotsatira zoonekeratu pa khungu loyera komanso lowala.Zhang Mu et al.yotengedwa ndi kuphunzira Chinese zitsamba akupanga monga Scutellaria baicalensis, Polygonum cuspidatum ndi Burnet, ndipo zotsatira anasonyeza kuti akupanga akhoza ziletsa selo kuchulukana mosiyanasiyana, ziletsa kwambiri ntchito ya okhudza maselo ambiri tyrosinase, ndi kuchepetsa kwambiri okhudza maselo ambiri melanin okhutira, kuti akwaniritse zotsatira za freckle whitening.
chitetezo cha dzuwa
Nthawi zambiri, mafuta oteteza ku dzuwa omwe amagwiritsidwa ntchito kwambiri pa zodzoladzola zodzitetezera ku dzuwa amagawidwa m'magulu awiri: imodzi ndi UV absorbers, yomwe ndi mankhwala achilengedwe, monga ketoni;ina ndi UV shielding agents, ndiko kuti, zoteteza dzuwa, monga TiO2, ZnO.Koma mitundu iwiriyi ya mafuta oteteza ku dzuwa imatha kuyambitsa kupsa mtima kwapakhungu, kuyabwa pakhungu, ndi kutsekeka kwa pores.Komabe, zomera zambiri zachilengedwe zimakhala ndi mayamwidwe abwino pa cheza cha ultraviolet, ndipo mosalunjika zimalimbitsa ntchito zoteteza dzuwa pochepetsa kuwonongeka kwa cheza cha ultraviolet pakhungu.
Kuphatikiza apo, zopangira zodzitetezera ku dzuwa zomwe zili muzomera zimakhala ndi zabwino zochepetsera kupsa mtima kwapakhungu, kukhazikika kwazithunzi, chitetezo ndi kudalirika poyerekeza ndi mankhwala azikhalidwe komanso zoteteza dzuwa.Zheng Hongyan et al.adasankha zopangira zitatu zachilengedwe, cortex, resveratrol ndi arbutin, ndipo adaphunzira zachitetezo ndi UVB ndi UVA zodzitchinjiriza zodzoladzola zawo zoteteza dzuwa kudzera m'mayesero amunthu.Zotsatira za kafukufuku zikuwonetsa kuti: zotulutsa zina zachilengedwe zimawonetsa chitetezo chabwino cha UV.Direction ndi ena adagwiritsa ntchito tartary buckwheat flavonoids ngati zida zopangira kuti aphunzire mawonekedwe a dzuwa a flavonoids.Kafukufukuyu adapeza kuti kugwiritsa ntchito ma flavonoids ku emulsions yeniyeni ndikuphatikiza ndi zoteteza thupi ndi mankhwala zoteteza dzuwa kumapereka maziko ofotokozera akugwiritsa ntchito zodzikongoletsera zamaluwa muzodzola mtsogolo.
