Niacinamideluhlobo lwevithamin B3 ehlala isetyenziswa kwiimveliso zokhathalelo lwesikhumba ngenxa yeenzuzo zayo ezahlukeneyo eluswini.Enye yeempembelelo zayo ezidumileyo kukukwazi ukukhanyisa kunye nokukhanya kwesikhumba, okwenza kube yinto eqhelekileyo kwiimveliso ezithengiswayo ngenxa yokukhanya kwesikhumba okanye ukulungiswa kwethoni yesikhumba.Kule ngxelo yovavanyo lomzimba womntu, siya kuphonononga isiphumo sokwenziwa mhlophe kwe-niacinamide eluswini.
Uvavanyo lubandakanya abathathi-nxaxheba be-50 abahlulwe ngokungaqhelekanga ngamaqela amabini: iqela lokulawula kunye neqela elisebenzisa imveliso equkethe i-5% ye-niacinamide.Abathathi-nxaxheba bayalelwa ukuba basebenzise imveliso ebusweni babo kabini ngosuku kwithuba leeveki ze-12.Ekuqaleni kwesifundo kwaye ekupheleni kwexesha leeveki ezili-12, imilinganiselo ithathwe kwithoni yesikhumba yabathathi-nxaxheba kusetyenziswa i-colorimeter, elinganisa ubunzulu be-pigmentation yesikhumba.
Iziphumo zabonisa ukuba kukho uphuculo olubonakalayo kwithoni yesikhumba kwiqela elisebenzisayoniacinamideimveliso xa kuthelekiswa neqela lolawulo.Abathathi-nxaxheba kwiqela le-niacinamide babonise ukunciphisa i-pigmentation yesikhumba, ebonisa ukuba ulusu lwabo luye lwaba lula kwaye lukhanya ngakumbi kwiiveki ze-12.Ukongeza, akukho ziphumo zibi zichazwe nguye nawuphi na wabathathi-nxaxheba kulo naliphi na iqela, ebonisa ukuba i-niacinamide sisithako esikhuselekileyo nesinyamezeleke kakuhle sokusetyenziswa kwiimveliso zokhathalelo lwesikhumba.
Ezi ziphumo ziyahambelana nezifundo zangaphambili ezibonise ukuqaqamba kolusu kunye neziphumo ezikhanyayo ze-niacinamide.INiacinamide isebenza ngokuthintela ukuveliswa kwemelanin, isidali-bala esinika ulusu umbala walo.Oku kuyenza ibe sisithako esisebenzayo sokunciphisa i-hyperpigmentation, njengamabala eminyaka okanye i-melasma, kunye nokuqaqambisa ithoni yesikhumba ngokubanzi.Ukongeza, i-niacinamide ibonakaliswe ukuba ine-anti-inflammatory kunye ne-antioxidant properties, enokunceda ukukhusela ulusu kumonakalo kunye nokuphucula impilo kunye nokubonakala kwayo.
Ukuqukumbela, le ngxelo yovavanyo lomzimba womntu ibonelela ngobungqina obungakumbi bokukhanya kwesikhumba kunye neziphumo ezikhanyayo.
