●Kungani Umzimba Womuntu Ukhiqiza I-melanin?
Ukuchayeka elangeni kuyimbangela enkulu yokukhiqizwa kwe-melanin. Imisebe ye-ultraviolet ekukhanyeni kwelanga ilimaza i-deoxyribonucleic acid, noma i-DNA, emangqamuzaneni. I-DNA eyonakele ingaholela ekulimaleni nasekuhlukanisekeni kolwazi lofuzo, futhi ibangele nokuguqulwa kwezakhi zofuzo ezimbi, noma ukulahlekelwa izakhi zofuzo ezicindezela isimila, okuholela ekuveleni kwezimila.
Kodwa-ke, ukuchayeka elangeni "akubi", futhi konke lokhu "kuyisikweletu" ku-melanin. Eqinisweni, ngezikhathi ezibucayi, i-melanin izokhishwa, ibambe ngokuphumelelayo amandla emisebe ye-ultraviolet, ivimbele i-DNA ukuba ingalimazi, ngaleyo ndlela inciphise umonakalo obangelwa imisebe ye-ultraviolet emzimbeni womuntu. Nakuba i-melanin ivikela umzimba womuntu emonakalweni we-ultraviolet, ingenza futhi isikhumba sethu sibe mnyama futhi sibe namabala. Ngakho-ke, ukuvimbela ukukhiqizwa kwe-melanin kuyindlela ebalulekile yokwenza isikhumba sibe mhlophe embonini yobuhle.
●YiniI-Arbutin?
I-Arbutin, eyaziwa nangokuthi i-arbutin, inefomula yamakhemikhali engu-C12H16O7. Kuyisithako esikhishwe emaqabunga e-Ericaceae plant bearberry. Ingavimbela umsebenzi we-tyrosinase emzimbeni futhi ivimbele ukukhiqizwa kwe-melanin, ngaleyo ndlela inciphise umbala wesikhumba, isuse amabala namabala. Ibuye ibe nemiphumela ebulala amagciwane kanye ne-anti-inflammatory futhi isetshenziswa kakhulu kuzimonyo.
I-Arbutiningahlukaniswa ngo-α-uhlobo no-β-ngokwezakhiwo ezahlukene. Umehluko omkhulu phakathi kwalokhu okubili ezimpahleni ezingokomzimba ukujikeleza kwe-optical: i-α-arbutin icishe ibe ngama-degree angu-180, kuyilapho i-β-arbutin icishe ibe -60. Zombili zinomphumela wokuvimbela i-tyrosinase ukuze kuzuzwe ubumhlophe. Okusetshenziswa kakhulu uhlobo lwe-β, olushibhile. Kodwa-ke, ngokocwaningo, ukungeza uhlobo lwe-α olulingana no-1/9 wokugxiliswa kohlobo lwe-β kungavimbela ukukhiqizwa kwe-tyrosinase futhi kuzuze ukumhlophe. Imikhiqizo eminingi yokunakekelwa kwesikhumba ene-α-arbutin eyengeziwe inomphumela omhlophe ophindwe kashumi kune-arbutin yendabuko.
●Ziyini Izinzuzo ZazoI-Arbutin?
I-Arbutin ikhishwa ikakhulukazi emaqabunga e-bearberry. Ingatholakala futhi kwezinye izithelo nezinye izitshalo. Inomphumela wokukhanyisa isikhumba. Ingakwazi ukungena ngokushesha esikhumbeni ngaphandle kokuthinta amangqamuzana esikhumba. Ihlanganisa ne-tyrosine, ebangela ukukhiqizwa kwe-melanin, futhi ingavimbela ngokuphumelelayo umsebenzi we-tyrosinase nokukhiqizwa kwe-melanin, ukusheshisa ukubola nokuqedwa kwe-melanin. Ngaphezu kwalokho, i-arbutin ingavikela isikhumba kuma-radicals mahhala futhi ine-hydrophilicity enhle. Ngakho-ke, kuvame ukungezwa emikhiqizweni emhlophe emakethe, ikakhulukazi emazweni ase-Asia.
I-Arbutinkuyinto yemvelo esebenzayo etholakala ezitshalweni eziluhlaza. Kuyingxenye ye-skin decolorizing ehlanganisa "izitshalo eziluhlaza, eziphephile futhi ezinokwethenjelwa" kanye "ne-decolorization ephumelelayo". Ingangena ngokushesha esikhumbeni. Ngaphandle kokuthinta ukugxila kokwanda kwamaseli, kungavimbela ngokuphumelelayo umsebenzi we-tyrosinase esikhumbeni futhi kuvimbele ukwakheka kwe-melanin. Ngokuhlanganisa ngokuqondile ne-tyrosinase, isheshisa ukubola nokukhishwa kwe-melanin, ngaleyo ndlela inciphise umbala wesikhumba, isuse amabala nama-freckles, futhi ayinayo i-toxic, ecasulayo, ezwelayo kanye neminye imiphumela emibi kuma-melanocyte. Ibuye ibe nemiphumela ye-bactericidal ne-anti-inflammatory. Iyindlela ephephe kunazo zonke nesebenza ngempumelelo yokwenza mhlophe impahla eluhlaza edumile namuhla, futhi iyinhlangano efanelekile yokwenza mhlophe yesikhumba kanye ne-ejenti esebenzayo yama-freckle ekhulwini lama-21.
●Iyini Ukusetshenziswa Okuyinhloko KweI-Arbutin?
Ingasetshenziswa ku-cosmetics ephezulu futhi ingenziwa ukhilimu wokunakekelwa kwesikhumba, ukhilimu we-freckle, ukhilimu we-pearl ephezulu, njll. Ayikwazi nje kuphela ukuhlobisa nokuvikela isikhumba, kodwa futhi ibe yi-anti-inflammatory and anti-irritant.
Izinto ezingasetshenzisiwe zomuthi wokushiswa nokushisa: I-Arbutin iyisithako esiyinhloko somuthi omusha wokusha kanye ne-scald, obonakala ngokukhululeka ngokushesha kwezinhlungu, umphumela onamandla wokulwa nokuvuvukala, ukuqedwa ngokushesha kokubomvu nokuvuvukala, ukuphulukiswa okusheshayo, futhi akukho zibazi.
Ifomu lomthamo: fafaza noma faka.
Izinto ezisetshenziswayo zomuthi wokulwa nokuvuvukala emathunjini: imiphumela emihle ye-bactericidal ne-anti-inflammatory, ayikho imiphumela emibi enobuthi.
