I-Arbutin, eyaziwa nangokuthi i-Arbutin, iyikristalu emhlophe e-acicular noma impushana. Amaqabunga akhishwe esithelweni sebhere angavimbela ukwakheka kwe-melanin ngokuvimbela umsebenzi we-Tyrosinase emzimbeni, ngaleyo ndlela anciphise ukufakwa kwe-pigment yesikhumba, asuse amabala ombala nama-freckles, kanye nokuba nemiphumela ebulalayo kanye ne-anti-inflammatory. Ikakhulukazi esetshenziselwa ukulungiswa kwezimonyo eziphezulu.
Igama lesiNgisi: Arbutin
I-Arbutin ihlukaniswe yaba yi-β- Ursolin (Beta arbutin) kanye ne-α-Arbutin (i-alpha arbutin), α-Arbutin
Umehluko phakathi kwalokhu okubili:
Iningi arbutin emakethe kuyintob- Arbutin, α- Abakhiqizi abambalwa kuphela abakhiqiza i-arbutin, futhi intengo cishe iphindwe izikhathi ezingu-8 kuneyangaphambili. Kodwa umphumela wokuba mhlophe uphindwe izikhathi ezingaphezu kwezingu-15 kunalowo wangaphambili.
Umehluko omkhulu ezimpahleni zomzimba phakathi kwalokhu okubili ukujikeleza kwazo kokubona: α- Okuqukethwe kwe-arbutin kungama-degree angama-180, kuyilapho i-β- Arbutin icishe ibe -60.
I-Arbutin iyisithako esisebenzayo semvelo esivela ku-Viridiplantae. Kuyingxenye ye-bleaching yesikhumba ehlanganisa "i-Viridiplantae, ukuphepha nokuthembeka" kanye "nokukhipha umbala okusebenzayo". Ingangena ngokushesha esikhumbeni, ivimbele ngokuphumelelayo umsebenzi we-Tyrosinase esikhumbeni, ivimbele ukwakheka kwe-melanin, futhi isheshise ukubola kanye nokuphuma kwe-melanin ngokuzihlanganisa ngokuqondile ne-tyrosinase ngaphandle kokuthinta ukugxila kokwanda kwamaseli, kunganciphisa ukufakwa kwe-pigment yesikhumba, susa amabala ombala namabala, futhi ayinazo izinto ezinobuthi, ezicasulayo, zokungezwani komzimba neminye imiphumela emibi I-Chromatophore. Ngesikhathi esifanayo, ingaphinde ibulale amagciwane futhi inciphise ukuvuvukala. Kuyisithako esiphephe kunazo zonke nesisebenza kahle kakhulu sokwenza mhlophe esidumile njengamanje, futhi siyindlela efanelekile yokwenza mhlophe yesikhumba kanye ne-ejenti ekhipha amabala esebenzayo ekhulwini lama-21.
Ungayengeza Kanjani I-Arbutin Emzileni Wakho Wokunakekela Isikhumba
Ungasebenzisa i-arbutin ngokuphephile ekugxiliseni okufika kumaphesenti angu-2 kumakhilimu obuso kanye namaphesenti angu-0.5 ezigcotshweni zomzimba, u-Chiu uphawula, wengeza ngokuthi isithako “siphephile futhi asinamandla kangako uma siqhathaniswa ne-hydroquinone.” (Nakuba i-hydroquinone ekugxilweni kwayo ngaphezu kwephesenti elingu-1 iye yavinjelwa emikhiqizweni yezimonyo e-EU, Japan, Australia, kanye namazwe amaningana e-Afrika, i-arbutin iphephile ekugxilweni okungenhla ngoba i-hydroquinone ikhishwa kancane futhi isikhumba asivezwa kakhulu. ngayo nganoma isiphi isikhathi, uyachaza.)
I-Arbutin iyisithako esikhanyisa isikhumba esiqondise amabala amnyama, i-hyperpigmentation, nezibazi. Yize inamandla amancane uma iqhathaniswa ne-hydroquinone, inephrofayili yokuphepha eqinile enezingozi ezimbalwa zemiphumela emibi.
