I-Niacinamideluhlobo lwevithamini B3 olusetyenziswa rhoqo kwiimveliso zokhathalelo lolusu ngenxa yeenzuzo zalo ezahlukeneyo kulusu. Enye yeziphumo zayo ezidumileyo kukukwazi kwayo ukukhanyisa nokukhanyisa ulusu, nto leyo eyenza ukuba lube sisithako esiqhelekileyo kwiimveliso ezithengiswayo zokwenza ulusu lube mhlophe okanye lulungiswe ithoni yolusu. Kule ngxelo yovavanyo lomzimba womntu, siza kuhlola isiphumo sokwenza ulusu lube mhlophe se-niacinamide.
Olu vavanyo lubandakanye abathathi-nxaxheba abangama-50 abahlulwe ngokungacwangciswanga baba ngamaqela amabini: iqela lolawulo kunye neqela elisebenzisa imveliso equlethe i-5% ye-niacinamide. Abathathi-nxaxheba bayalelwe ukuba bafake imveliso ebusweni babo kabini ngemini kangangeeveki ezili-12. Ekuqaleni kolu phononongo nasekupheleni kwexesha leeveki ezili-12, kwathathwa imilinganiselo yesikhumba sabathathi-nxaxheba kusetyenziswa i-colorimeter, elinganisa ubukhali bombala wesikhumba.
Iziphumo zibonise ukuba kukho ukuphucuka okubalulekileyo ngokwezibalo kwithoni yolusu kwiqela elisebenzisai-niacinamideimveliso xa ithelekiswa neqela lolawulo. Abathathi-nxaxheba kwiqela le-niacinamide babonise ukwehla kombala wolusu, nto leyo ebonisa ukuba ulusu lwabo luye lwaba lukhanya ngakumbi kwixesha leeveki ezili-12. Ukongeza, akukho miphumo mibi exeliweyo ngabathabathi-nxaxheba kwiqela ngalinye, nto leyo ebonisa ukuba i-niacinamide sisithako esikhuselekileyo nesinyamezelayo sokusetyenziswa kwiimveliso zokhathalelo lolusu.
Ezi ziphumo zihambelana nezifundo zangaphambili ezibonise imiphumo yokukhanyisa nokukhanyisa ulusu ye-niacinamide. I-Niacinamide isebenza ngokuthintela ukuveliswa kwe-melanin, umbala onika ulusu umbala walo. Oku kuyenza ibe sisithako esisebenzayo sokunciphisa i-hyperpigmentation, njengeendawo ezidala okanye i-melasma, kunye nokukhanyisa ithoni yolusu iyonke. Ukongeza, i-niacinamide ibonakalisiwe ukuba ineempawu zokulwa nokuvuvukala kunye ne-antioxidant, ezinokunceda ukukhusela ulusu ekonakaleni kwaye ziphucule impilo yalo iyonke kunye nenkangeleko.
Ukuqukumbela, le ngxelo yovavanyo lomzimba womntu inika ubungqina obongezelelekileyo bemiphumo yokukhanya kolusu kunye nokukhanya.
