FARSAMADA FARSAMADA
VC Ether ether ether ethy ether waxay si toos ah u gaari kartaa melanocytes lakabka asalka ah iyada oo loo marayo goynta, xannibida dhaqdhaqaaqa loo yaqaan 'toyrosinase', oo xakameynaya samaynta melanin, oo ay si wax ku ool ah u soo celiyaan melanin, sidaas darteed si wax ku ool ah u cabaya maqaarka. Intaas waxaa sii dheer, VC Ether ether waxay si toos ah uga qeybqaadan kartaa isku-darka isku-darka ah ee loo yaqaan 'Colates' oo hagaajin kara waxqabadka maqaarka kadib markii uu kordhiyo lo'da, ka dhigo maqaarka oo buuxa, oo maqaarka jilicsan oo jilicsan. 3-o-andyly-L-ascorbic acid waxay noqon kartaa xasillooni weyn oo waxtar u leh P-hydroxyacetophenone xalka.
