INCI | Molecula | MW |
Nikotinamide, Pyridine-3-Carboxyamide | C6H6N2O | 122.13 |
Gukemura: Kubora mumazi n'inzoga, gushonga muri glycerine
2.Gusaba:
Ni iya Vitamine B, igira uruhare mu guhindagurika mu mubiri, irashobora gukoreshwa mu kwirinda pellagra cyangwa izindi ndwara ziterwa na niacin.Ikoreshwa muri farumasi, ibiryo byongera Ibi bicuruzwa bikora kuburyo bukurikira:
Ubwa mbere, melanin yimbitse muruhu rwa selile ya melanin, ariko kuriyi nshuro, nayo imbere, nyuma amahema yimurirwa muri selile keratin ikikije, nicotinamide irashobora kubangamira ihererekanyabubasha rya melanin, bigatuma melanin iba melanocyte kuguma imbere kugirango itaza. hanze, ntabwo rero izakomeza gukora melanin melanin selile, Icya kabiri, melanin ntabwo izabonwa nijisho ryumuntu hejuru yuruhu, kugirango igere ku ngaruka zo kwera.
Icya kabiri, niacinamide yerekana ko ifite ingaruka nziza zo kwiyegurira Imana, cyane cyane nyuma ya 2015, ijambo "gutamba igitambo ubushakashatsi bwimbitse, indwara nyinshi zifatika zerekanaga ko hamwe no gutamba (maillard reaction), ibikoresho byakozwe nigitambo ari umukara, birashobora kureka uruhu rusa n'umukara, so mash resistance nayo ifasha kwera.ves, ibiryo byongera ibiryo, kwisiga, nibindi.
Mu igeragezwa ryagenzuwe ku ngingo 20, inshuro nyinshi ikoti rimwe na rimwe ya nikotinamide ku gipimo gito (0.2%) na byo byagize uruhare mu kugabanya ubudahangarwa bw'uruhu buterwa n'imirasire mito ya UV yigana izuba.0.2% yibitekerezo bifite akamaro, kandi mubisanzwe dukoresha nicotinamide ishingiye kubicuruzwa byuruhu byibanda kuri 2%, kwibanda kuri 4% ~ 5%.Koresha rero nikotinamide ikuramo mbere yo gukoresha izuba
