Kev Siv
Deoxyarbutin yog ib tiam tshiab ntawm cov tshuaj pleev ib ce uas ua rau daim tawv nqaij ci ntsa iab thiab dawb, uas feem ntau yog siv rau hauv cov tshuaj pleev ib ce uas ua rau daim tawv nqaij dawb. Nws tuaj yeem tiv thaiv kev ua haujlwm ntawm tyrosinase, tswj kev tsim melanin, kov yeej cov xim pigmentation, ploj cov pob dub, thiab muaj cov nyhuv ua kom daim tawv nqaij dawb sai thiab ntev. Deoxyarbutin kuj muaj cov nyhuv antioxidant muaj zog. Cov nyhuv inhibitory ntawm deoxyaarbutin ntawm tyrosinase yog qhov zoo dua li lwm cov tshuaj ua kom daim tawv nqaij dawb. Nws cov nyhuv ua kom daim tawv nqaij dawb yog 350 npaug ntawm arbutin, 150 npaug ntawm kojic acid, thiab 10 npaug ntawm hydroquinone. Piv nrog rau yav dhau los, nws muaj kev nyab xeeb dua thiab ruaj khov dua. Nws tsis yog tsuas yog tsis muaj tshuaj lom thiab tsis ua rau daim tawv nqaij khaus, tab sis kuj yooj yim heev rau daim tawv nqaij nqus tau. Nrog me ntsis ntawm kev siv, nws tuaj yeem ua rau daim tawv nqaij dawb thiab ci ntsa iab. Nws suav hais tias yog ib qho tshuaj pleev ib ce uas muaj kev nyab xeeb heev.
