Kugwiritsa ntchito

Arbutin imapangitsa kuti khungu liziwala. Imatha kulowa kulowa mu khungu osakhudza khungu. Itha kuphatikiza ndi tyrosine zomwe zimapangitsa kuti ma melalanine azipanga, moyenera kuti aletse ntchito ya tyrosine ndi mapangidwe a melanin, ndikuthandizira kuwonongeka ndi kuchotsedwa kwa melanin. Kuphatikiza apo, Arbutin amathanso kuteteza khungu ndi ma radicals aulere ndipo ali ndi hydrophilicity yabwino

Kutumiza ndi kutumiza

Vacuum yonyamula m'matumba a aluminium foil ndi matumba apulasitiki, 1kg iliyonse. Arbutin ndi hygroscopic, chonde sungani pamalo ozizira komanso owuma.

Ndi wa zinthu wamba ndipo amatha kupulumutsa ndi nyanja kapena mpweya
