Arbutin
Arbutin, ekwabizwa ngokuba yi arbutin,
inaliti emhlophe okanye umgubo,
Ithiywe igama layo emva kokuba ikhutshwe kumagqabi ebhereberry.
I-Arbutin yenye yezona zinto zikhuselekileyo nezisebenzayo zokwenziwa zibe mhlophe ngoku zithandwa kumazwe aphesheya, kwaye ikwayeyona arhente ikhuphisanayo yokwenza mhlophe ulusu kunye nokususa amabala kwinkulungwane yama-21.
Kwizithambiso, inokwenza mhlophe ngokufanelekileyo kwaye isuse amabala eluswini, kwaye ngokuthe ngcembe iphele kwaye isuse amabala, i-chloasma, i-melanin, amaqhakuva kunye nobudala esikhumbeni. Ikhuseleke kakhulu kwaye ayinazo iziphumo ebezingalindelekanga ezifana nokucaphuka kunye nokwazisa. I-Arbutin i-hydrolyzed ngokulula kwaye kufuneka isetyenziswe kwi-pH ye-5-7. Ukuze uzinzise ukusebenza, isixa esifanelekileyo se-antioxidants ezifana ne-sodium bisulfite kunye ne-vitamin E zihlala zongezwa ukuze zifezekiseke ngcono, ukususwa kwe-freckle, ukuthambisa, ukuthamba, ukususwa kwemibimbi, kunye nemiphumo yokuchasana nokudumba.
I-Arbutin inciphisa ukuveliswa kwe-melanin ngokuthintela umsebenzi we-tyrosinase, i-enzyme eyenza i-melanin. Umgaqo wayo wesenzo uyafana neyeza elimhlophe le-hydroquinone.
Nangona kunjalo, i-hydroquinone ineziphumo ebezingalindelekanga kwaye ifuna izilumkiso ezininzi. Kufuneka isetyenziswe phantsi kwesikhokelo kunye nokubeka iliso likagqirha. Kukho iimolekyuli zeglucose eninzi kwisakhiwo se-arbutin kune-hydroquinone.
Inomsindo ophantsi kwaye unokongezwa ngokukhululekileyo kwiimveliso zokunakekelwa kwesikhumba kunye nomda woxinzelelo ophezulu ukuya kwi-7%.
Iimolekyuli ezisebenzayo ze-arbutin zinokungena kwisiseko solusu ukuze kukhanye ubunzulu bendawo, kwaye zinokunyanga i-chloasma, amabala amnyama, amabala elanga, kunye nokubabala kwebala okushiyekileyo kukwaliwa ngamachiza.
Zonke zineempembelelo zonyango ezinamandla, kodwa ukuba ugxininiso luphantsi kakhulu, ukuqina kwesiphumo kuya kuba buthathaka, ngoko ke i-5% yoxinaniso lugxininiso olukhuselekileyo kunye nolusebenzayo lokukhanyisa.
I-concentration ye-5% ikhawuleza kune-vitamin C ekukhanyiseni amabala, kwaye umphumo wokukhanyisa uzinzile kwaye awuyi kubangela ukucaphuka kwesikhumba.
Arbutin iya kuncitshiswa ibe yihydroquinone emva kokuba ifunxwe lusu. Oku kubangele ukuba abanye abantu bathandabuze ukhuseleko lwe-arbutin kwaye bakholelwa ukuba i-arbutin isenokuveliswa.
Imiphumo efana ne-Hydroquinone. Elona lizwi lixhaphakileyo lelokuba "iimveliso zokhathalelo lwe-arbutin azinakusetyenziswa emini, kungenjalo ulusu aluyi kuba mhlophe kwaye luya kuba mnyama."
Enyanisweni, akukho mfuneko yakukhathazeka. Iimvavanyo zibonise ukuba i-arbutin kuphela ene-concentration engaphezu kwe-7% inokukhathazeka ekukhanyeni. Ngoko ke, i-7% yindawo ebalulekileyo yokhuseleko. Kukho imimiselo ecacileyo yokongezwa kwezithako kwiimveliso zokunakekelwa kwesikhumba. Ubuninzi bomda wogxininiso yi-7%. Ngaphakathi kolu luhlu loxinaniso, i-arbutin ayanele ukuba ibangele i-photosensitivity, ngoko ayinakusetyenziswa ngaphandle kokukhusela ukukhanya.
Xa ifakwe esikhumbeni kwaye iboliswe ngokukhanya, iya kuncitshiswa ibe yi-hydroquinone, ivelise umphumo omhlophe. Uxinzelelo lwe-hydroquinone kwiimveliso zokhathalelo lwesikhumba ze-arbutin lungaphantsi kwe-20 ppm (oko kukuthi, iinxalenye ezingama-20 ngesigidi). Ngaphantsi komda woxinzelelo ophantsi ngolo hlobo, i-hydroquinone ayisayi kubangela iziphumo ebezingalindelekanga ezifana nokuba mnyama kwesikhumba.
Ukuba uyoyika ukusebenzisa iimveliso zokhathalelo lwesikhumba emini ngenxa yokuba ziqulethe i-arbutin, ke akuyomfuneko ukuba, ngaphandle kokuba iimveliso zokhathalelo lwesikhumba eziqulethe i-arbutin nazo zongeza ezinye izithako zokhathalelo lwesikhumba ezifuna ukukhuselwa ekukhanyeni.
Ngamafutshane, kufuneka ukhethe iimveliso zokunakekelwa kwesikhumba kwiimpawu ezithembekileyo, kwaye kungakhathaliseki ukuba usebenzisa ntoni, sebenzisa ukukhuselwa kwelanga emini.
