Niacinamide cyangwa nicotinamide (NAM) ni ubwoko bwa vitamine B3 iboneka mu biryo kandi ikoreshwa nk'inyongera y'imirire n'imiti.Nkinyongera, ikoreshwa kumunwa kugirango ikingire kandi ivure pellagra (kubura niacin).Mugihe aside nicotinike (niacin) ishobora gukoreshwa kubwiyi ntego, niacinamide ifite inyungu zo kudatera uruhu.Nka cream, ikoreshwa mukuvura acne.Ni vitamine ishonga.
Ingaruka zo ku ruhande ni nto.Mugihe kinini cyane ibibazo byumwijima birashobora kubaho.Amafaranga asanzwe afite umutekano mukoresha mugihe utwite.Niacinamide iri mumuryango wa vitamine B yimiti, cyane cyane vitamine B3.Ni amide ya acide nikotinike.Ibiryo birimo niacinamide birimo umusemburo, inyama, amata, n'imboga rwatsi.
Niacinamide yavumbuwe hagati ya 1935 na 1937. Ari ku rutonde rw’umuryango w’ubuzima ku isi w’imiti yingenzi.Niacinamide irahari nkimiti rusange kandi hejuru ya comptoir.Ubucuruzi, niacinamide ikozwe muri acide nicotinic (niacin) cyangwa nicotinonitrile.Mu bihugu byinshi ibinyampeke byiyongereyeho niacinamide.
Ni iya Vitamine B, igira uruhare mu guhinduranya umubiri mu mubiri, irashobora gukoreshwa mu gukumira pellagra cyangwa izindi ndwara ziterwa na niacin.Ikoreshwa muri farumasi, ibiryo byongera Ibi bicuruzwa bikora kuburyo bukurikira:
Ubwa mbere, melanin yimbitse muruhu rwakagari ka melanin, ariko iki gihe, nayo imbere, nyuma amahema yimurirwa muri selile keratin ikikije, nicotinamide irashobora kubangamira ihererekanyabubasha rya melanin, bigatuma melanin yabaye melanocyte guma imbere kugirango itaza hanze, ntabwo rero izakomeza kubyara melanin melanin selile, Icya kabiri, melanin ntizongera kubonwa nijisho ryumuntu hejuru yuruhu, kugirango igere ku ngaruka zera.
Icya kabiri, niacinamide yerekana ko ifite ingaruka nziza zo kwezwa, cyane cyane nyuma ya 2015, ijambo "gutamba igitambo ubushakashatsi bwimbitse cyane, indwara nyinshi zifata umubiri zerekanye ko hamwe nigitambo (maillard reaction), ibikoresho byakozwe nigitambo ari umukara, bishobora kureka uruhu rusa n'umukara, so mash resistance nayo ifasha kwera.ves, ibiryo byongera ibiryo, kwisiga, nibindi.
Mu igeragezwa ryagenzuwe ku masomo 20, amakoti yagiye asimburana rimwe na rimwe ya nikotinamide ku gipimo gito (0.2%) nayo yagize uruhare mu kugabanya ubudahangarwa bw'uruhu buterwa n'imirasire ya UV ifata imirasire y'izuba.0.2% yibitekerezo bifite akamaro, kandi mubisanzwe dukoresha nicotinamide ishingiye kubuvuzi bwibicuruzwa byuruhu muri rusange biri hejuru ya 2%, kwibanda cyane kuri 4% ~ 5%.Koresha rero nikotinamide ikuramo mbere yo gukoresha izuba.
