●Vim li cas tib neeg lub cev tsim melanin?
Kev raug tshav ntuj yog qhov tseem ceeb ntawm kev tsim melanin. Ultraviolet rays nyob rau hauv tshav ntuj puas deoxyribonucleic acid, los yog DNA, nyob rau hauv lub hlwb. Kev puas tsuaj DNA tuaj yeem ua rau muaj kev puas tsuaj thiab cuam tshuam ntawm cov ntaub ntawv caj ces, thiab txawm tias ua rau muaj kev hloov pauv ntawm cov noob caj noob ces, los yog poob ntawm cov qog suppressor noob, ua rau muaj cov qog nqaij hlav.
Txawm li cas los xij, kev raug tshav ntuj tsis yog "txaus ntshai", thiab qhov no yog tag nrho "credit" rau melanin. Qhov tseeb, nyob rau lub sijhawm tseem ceeb, melanin yuav raug tso tawm, nqus tau lub zog ntawm ultraviolet rays, tiv thaiv DNA los ntawm kev puas tsuaj, yog li txo qhov kev puas tsuaj los ntawm ultraviolet rays rau tib neeg lub cev. Txawm hais tias melanin tiv thaiv tib neeg lub cev los ntawm kev puas tsuaj ultraviolet, nws tuaj yeem ua rau peb cov tawv nqaij tsaus thiab tsim cov pob. Yog li ntawd, thaiv kev tsim cov melanin yog ib qho tseem ceeb ntawm cov tawv nqaij dawb hauv kev lag luam kev zoo nkauj.
● Dab tsi yogArbutin?
Arbutin, tseem hu ua arbutin, muaj cov tshuaj formula C12H16O7. Nws yog ib qho khoom xyaw muab rho tawm los ntawm nplooj ntawm Ericaceae cog bearberry. Nws tuaj yeem cuam tshuam kev ua haujlwm ntawm tyrosinase hauv lub cev thiab tiv thaiv kev tsim cov melanin, yog li txo cov tawv nqaij pigmentation, tshem tawm pob thiab freckles. Nws kuj muaj cov kab mob bactericidal thiab anti-inflammatory thiab feem ntau yog siv hauv tshuaj pleev ib ce.
Arbutintuaj yeem muab faib ua α-hom thiab β-hom raws li cov qauv sib txawv. Qhov sib txawv loj tshaj plaws ntawm ob qho tib si hauv lub cev yog qhov kev sib hloov kho qhov muag: α-arbutin yog li 180 degrees, thaum β-arbutin yog li -60. Lawv ob leeg muaj cov nyhuv ntawm inhibiting tyrosinase kom ua kom dawb. Feem ntau siv yog β-hom, uas yog pheej yig. Txawm li cas los xij, raws li kev tshawb fawb, ntxiv α-hom sib npaug rau 1/9 ntawm cov ntsiab lus ntawm β-hom tuaj yeem cuam tshuam kev tsim cov tyrosinase thiab ua kom tawv nqaij. Ntau cov khoom tu tawv nqaij nrog ntxiv α-arbutin muaj cov nyhuv whitening kaum npaug siab dua li cov tshuaj arbutin.
● Cov txiaj ntsig ntawm dab tsiArbutin?
Arbutin feem ntau yog muab rho tawm los ntawm nplooj ntawm bearberry. Nws tuaj yeem pom muaj nyob hauv qee cov txiv hmab txiv ntoo thiab lwm yam nroj tsuag.

Nws ua ke nrog tyrosine, uas ua rau kev tsim cov melanin, thiab tuaj yeem thaiv kev ua haujlwm ntawm tyrosinase thiab tsim cov melanin, ua kom lub decomposition thiab tshem tawm ntawm melanin. Tsis tas li ntawd, arbutin tuaj yeem tiv thaiv daim tawv nqaij los ntawm cov dawb radicals thiab muaj hydrophilicity zoo. Yog li ntawd, nws yog feem ntau ntxiv rau cov khoom ntxuav hniav dawb ntawm lub khw, tshwj xeeb tshaj yog nyob rau hauv cov teb chaws Esxias.
Arbutinyog ib yam khoom ntuj tsim tau los ntawm cov nroj tsuag ntsuab. Nws yog daim tawv nqaij decolorizing tivthaiv uas ua ke "cov nroj tsuag ntsuab, muaj kev nyab xeeb thiab txhim khu kev qha" thiab "ntau decolorization". Nws tuaj yeem nkag mus rau hauv daim tawv nqaij sai sai. Tsis muaj kev cuam tshuam cov cell proliferation concentration, nws tuaj yeem cuam tshuam cov haujlwm ntawm tyrosinase hauv daim tawv nqaij thiab thaiv kev tsim ntawm melanin. Los ntawm kev sib txuas ncaj qha nrog tyrosinase, nws ua kom nrawm nrawm thiab tshem tawm ntawm melanin, yog li txo cov tawv nqaij pigmentation, tshem tawm pob thiab freckles, thiab tsis muaj tshuaj lom, khaus, rhiab thiab lwm yam teebmeem ntawm melanocytes. Nws kuj muaj cov kab mob bactericidal thiab tiv thaiv inflammatory.
