Niacinamidekuyindlela yevithamini B3 evame ukusetshenziswa kwimikhiqizo ye-skincare ngenxa yezinzuzo zayo ezahlukahlukene zesikhumba. Enye yemiphumela ethandwa kakhulu yikhono layo lokukhanyisa futhi likhanyise isikhumba, okwenza kube yisithako esivamile emikhiqizweni ethengiswayo lapho kunwetshwa khona noma ukulungiswa kwethoni lesikhumba. Kulombiko lo mbiko womzimba womuntu, sizohlola umphumela onzima weNiacinamide esikhunjeni.
Ukuhlolwa kubandakanya ababambiqhaza abangama-50 ababehlukaniswe ngamaqembu amabili: iqembu elilawulayo neqembu lisebenzisa umkhiqizo oqukethe ama-nacinamide angama-5%. Ababambiqhaza bayalwa ukuba basebenzise umkhiqizo ebusweni babo kabili ngosuku isikhathi esingamasonto ayi-12. Ekuqaleni kocwaningo nasekupheleni kwenkathi yamasonto ayi-12, kuthathwe izilinganiso zethoni lesikhumba lababambiqhaza besebenzisa umbala we-colorimeter, okulinganisa ukuqina kombala wesikhumba.
Imiphumela ikhombisile ukuthi kunokuthuthuka okubalulekile ngokwezibalo ngethoni yesikhumba eqenjini kusetshenziswaniacinamideumkhiqizo uma uqhathaniswa neqembu elilawulayo. Ababambiqhaza eqenjini leNiacinamide bakhombisa ukuncishiswa kombala wesikhumba, okukhombisa ukuthi isikhumba sabo sase silula futhi sikhanye isikhathi esingaphezu kwesonto le-12. Ngaphezu kwalokho, kwakungekho miphumela emibi ebikiwe yinoma yimuphi wabahlanganyeli eqenjini, ekhombisa ukuthi uNiacinamide uyisithako esiphephile futhi esibekelwe kahle ukuze sisetshenziswe emikhiqizweni ye-skincare.
Le miphumela ihambisana nezifundo ezedlule ezikhombise ukukhanyisa isikhumba nokukhanyisa imiphumela yeNiacinamide. I-niacinamide isebenza ngokuvimbela ukukhiqizwa kukaMelanin, i-pigment enikeza isikhumba umbala wayo. Lokhu kwenza kube yisithako esisebenzayo sokunciphisa i-hyperpigmentation, njengezindawo zobudala noma i-melasma, kanye nokukhanyisa ithoni yesikhumba ephelele. Ngaphezu kwalokho, i-niacinamide ikhonjiswe ukuthi inezakhiwo ezilwa nokuvuvukala kanye nezakhiwo ze-antioxidant, ezingasiza ukuvikela isikhumba emonakalweni futhi zithuthukise impilo yayo nokubukeka kwayo jikelele.
Ekuphetheni, lo mbiko wokuhlola umzimba womuntu unikeza ubufakazi obengeziwe bokukhanyisa isikhumba nokukhanyisa imiphumela.
