Arbutinyog ib qho kev sib txuas ua ke tau pom nyob hauv ntau yam nroj tsuag xws li beileberry, cranberries, thiab blueberries. Nws tau txais kev saib xyuas tseem ceeb nyob rau hauv kev lag luam nyuaj thiab kev lag luam kom zoo nkauj vim nws lub peev xwm ntawm daim tawv nqaij ntxuav hniav dawb thiab teeb pom kev zoo. Tus kws kho tshuab qab cov tshuaj ntxuav hniav dawb ntawm arbutin reeg nyob rau hauv kev tsim khoom ntawm cov tawv nqaij - lub luag hauj lwm muaj lub luag hauj lwm, plaub hau, thiab qhov muag xim.
Daim tawv nqaij cov xim yog txiav txim los ntawm cov nyiaj thiab faib cov melanin tsim los ntawm Melanocytes, cov txheej txheem tshwj xeeb hauv cov txheej txheej epidermal. Tyrosinase yog tus tseem ceeb enzyme nyob rau hauv melanin synthesis pathwhwy, uas thaum kawg coj mus rau kev tsim ntawm melanin pigments. Arbutin nthuav dav nws cov kev ntxuav hniav dawb uas feem ntau los ntawm kev sib tw inhibition ntawm tyrosinase kev ua.
Arbutin muaj cov kev sib cog lus glycoside, uas yog qhov sib txuas lus tshuaj lom neeg ntawm cov piam thaj ua ke thiab cov roj hydroquinone molecule. Hydroquinone yog qhov muaj npe zoo sib xyaw ua ke nrog daim tawv nqaij-teeb pom kev zoo, tab sis nws tuaj yeem ua rau ntawm daim tawv nqaij thiab cuam tshuam nrog cov kev mob tshwm sim. Arbutin, ntawm qhov tod tes, ua raws li txoj kev mus rau hydroquinone thaum tseem muaj kev txwv me me.
Thaum arbutin tau thov rau daim tawv nqaij, nws yog nqus thiab metabolized rau hauv hydroquinone los ntawm cov txheej txheem enzymatic. No hydroquinone ces kev sib tw inhibits qhov kev txiav txim ntawm Tyrosinase los ntawm kev ua haujlwm nws lub chaw nquag. Raws li qhov tshwm sim, Tyrosine molecules tsis tuaj yeem hloov dua siab tshiab rau hauv melanin precursors, ua rau cov melanin tsawg. Qhov kawg no qhov ua tau rau kev txo qis zuj zus hauv daim tawv nqaij tawv nqaij, ua rau lub teeb ci dua thiab ntau dua txawm tias cov tawv nqaij.
Nws yog ib qho tseem ceeb kom nco ntsoov tiasArbutin lub whiteningQhov cuam tshuam tsis yog. Daim tawv nqaij tig tau siv sijhawm li ib hlis, yog li kev siv ntawm arbutin-muaj cov khoom lag luam yog qhov tsim nyog los soj ntsuam cov kev hloov pauv ntawm daim tawv nqaij. Tsis tas li ntawd, Arbutin lub tshuab ntawm kev ua yog ua tau zoo rau kev daws teeb meem ntsig txog kev hyperpigmentation, xws li cov hnub nyoog, thiab hloov pauv cov tawv nqaij daim tawv nqaij.
Arbutin cov ntaub ntawv kev nyab xeeb feem ntau tau thev naus laus zis dua li lwm tus neeg saib xyuas tawv nqaij, ua rau nws xaiv cov tawv nqaij tsis ncaj. Txawm li cas los xij, cov kev tshwm sim tuaj yeem sib txawv, thiab nws raug nquahu kom ua ib daim duab kuaj ua ntej muab cov khoom lag luam sib txawv tshiab rau hauv koj txoj kev niaj hnub.
Hauv kev xaus, daim tawv nqaij ntxuav tawv nqaij ntawm nws lub peev xwm ua rau muaj kev ua haujlwm me me. Nws cov kev sib tw inhibition ntawm tyrosinase, uas ua rau txo qis melanin synthesis, ua rau nws rov hais dua hauv tawv nqaij tawv nqaij tsom iav thiab tawv nqaij tsis sib xws. Raws li nrog cov khoom siv tawv nqaij tawv, nws pom zoo los sab laj nrog cov khoom lag luam tshiab rau koj cov kev txhawj xeeb tshiab, tshwj xeeb yog tias koj muaj kev txhawj xeeb txog daim tawv nqaij lossis cov xwm txheej tshwj xeeb.
