●Kutheni Umzimba Womntu Uvelisa iMelanin?
Ukugqatswa lilanga ngoyena nobangela wemveliso yemelanin. Imitha yeultraviolet ekukhanyeni kwelanga yonakalisa i-deoxyribonucleic acid, okanye i-DNA, kwiiseli. I-DNA eyonakeleyo inokukhokelela kumonakalo kunye nokuchithwa kolwazi lwemfuza, kwaye kubangele utshintsho olubi lwemfuza, okanye ilahleko yemfuza ye-tumor suppressor, ekhokelela ekuveleni kwamathumba.
Nangona kunjalo, ukukhanya kwelanga "akubi kakhulu", kwaye konke oku "ityala" kwi-melanin. Enyanisweni, ngexesha elinzima, i-melanin iya kukhutshwa, ibambe ngokufanelekileyo amandla emitha ye-ultraviolet, ukukhusela i-DNA ukuba ingonakaliswe, ngaloo ndlela inciphisa umonakalo obangelwa yimisebe ye-ultraviolet emzimbeni womntu. Nangona i-melanin ikhusela umzimba womntu kumonakalo we-ultraviolet, inokwenza ulusu lwethu lube mnyama kwaye luphuhlise amabala. Ke ngoko, ukuthintela ukuveliswa kwe-melanin yindlela ebalulekileyo yokwenziwa mhlophe kwesikhumba kwishishini lobuhle.
●YintoniArbutin?
I-Arbutin, eyaziwa ngokuba yi-arbutin, inefomula yekhemikhali ye-C12H16O7. Isithako esithathwe kumagqabi e-Ericaceae plant bearberry. Inokuthintela umsebenzi we-tyrosinase emzimbeni kwaye ithintele ukuveliswa kwe-melanin, ngaloo ndlela inciphisa i-pigmentation yesikhumba, isuse amabala kunye ne-freckles. Kwakhona ineempembelelo ze-bactericidal kunye ne-anti-inflammatory kwaye isetyenziswa kakhulu kwi-cosmetics.
Arbutininokwahlulwa ibe yi-α-udidi kunye nohlobo lwe-β ngokwezakhiwo ezahlukeneyo. Umahluko omkhulu phakathi kwezi zimbini kwiimpawu ezibonakalayo kukujikeleza kwe-optical: i-α-arbutin imalunga ne-180 degrees, ngelixa i-β-arbutin imalunga -60. Bobabini banempembelelo yokuthintela i-tyrosinase ukufezekisa ubumhlophe. Eyona isetyenziswa kakhulu ludidi lwe-β, olunexabiso eliphantsi. Nangona kunjalo, ngokophando, ukongeza uhlobo lwe-α olulingana ne-1/9 yoxinaniso lwe-β-uhlobo lunokuthintela ukuveliswa kwe-tyrosinase kunye nokufezekisa umhlophe. Iimveliso ezininzi zokhathalelo lwesikhumba ezine-α-arbutin ezongeziweyo zinefuthe elimhlophe eliphindwe kalishumi kune-arbutin yesintu.
●Ziziphi iiNzuzoArbutin?
IArbutin itsalwa ikakhulu kumagqabi ebhereberry. Inokufumaneka nakwezinye iziqhamo nakwezinye izityalo. Inomphumela wokukhanyisa ulusu. Inokungena ngokukhawuleza kwesikhumba ngaphandle kokuchaphazela iiseli zesikhumba. Idibanisa ne-tyrosine, ebangela ukuveliswa kwe-melanin, kwaye inokuthintela ngokufanelekileyo umsebenzi we-tyrosinase kunye nokuveliswa kwe-melanin, ukukhawuleza ukubola kunye nokupheliswa kwe-melanin. Ukongeza, i-arbutin inokukhusela ulusu kwiiradicals zasimahla kwaye ine-hydrophilicity elungileyo. Ke ngoko, ihlala yongezwa kwiimveliso ezimhlophe kwimarike, ngakumbi kumazwe aseAsia.
Arbutinyinto yendalo esebenzayo ephuma kwizityalo eziluhlaza. Iyinxalenye ye-skin decolorizing edibanisa "izityalo eziluhlaza, ezikhuselekileyo nezithembekileyo" kunye "ne-decolorization esebenzayo". Inokungena ngokukhawuleza esikhumbeni. Ngaphandle kokuchaphazela i-concentration ye-cell proliferation, inokuthintela ngokufanelekileyo umsebenzi we-tyrosinase kwesikhumba kwaye ivimbele ukubunjwa kwe-melanin. Ngokudibanisa ngokuthe ngqo kunye ne-tyrosinase, ikhawuleza ukubola kunye nokukhutshwa kwe-melanin, ngaloo ndlela inciphisa i-pigmentation yesikhumba, isusa amabala kunye ne-freckles, kwaye ayinayo ityhefu, inomsindo, i-sensitizing kunye nezinye iziphumo zecala kwi-melanocytes. Kwakhona ineempembelelo ze-bactericidal kunye ne-anti-inflammatory. Yeyona nto ikhuselekileyo nesebenzayo yokwenza mhlophe imathiriyeli ekrwada ethandwayo namhlanje, kwaye ikwayeyona ndawo ifanelekileyo yokwenza mhlophe ulusu kunye ne-reckle esebenzayo kwinkulungwane yama-21.
● Yintoni eyona nto isetyenziswayoArbutin?
Ingasetyenziselwa izimonyo eziphezulu kwaye ingenziwa kwikhilimu yokunakekelwa kwesikhumba, i-freckle cream, i-pearl cream ephezulu, njl.
Izixhobo eziluhlaza zokutshisa kunye neyeza lokutshisa: I-Arbutin sesona sithako siphambili seyeza elitsha lokutshisa kunye ne-scald, elibonakala ngokukhululeka kweentlungu ezikhawulezayo, impembelelo enamandla yokuchasana nokudumba, ukuphelisa ngokukhawuleza ububomvu kunye nokudumba, ukuphilisa ngokukhawuleza, kwaye akukho ziva.
Ifomu yethamo: fafaza okanye ugalele.
Izinto eziluhlaza zonyango oluchasayo lwamathumbu: imiphumo emihle ye-bactericidal kunye ne-anti-inflammatory, akukho miphumo emibi yetyhefu.
