2. Ntchito:
Ndi vitamini B, kutenga nawo gawo mu kagayidwe mu thupi, angagwiritsidwe ntchito kuteteza pellagra kapena matenda ena niacin defection.Imagwiritsidwa ntchito ku pharmacy, kuwonjezera pazakudyaIzi zimagwira ntchito motere:
Choyamba, melanin kwambiri khungu la melanin selo, koma nthawi ino, komanso mkati, kenako tentacles umasamutsidwa ozungulira maselo keratin, nicotinamide akhoza kusokoneza kulanda melanin, kupanga melanin wakhala melanocyte kukhala mkati kuti asabwere. kunja, kotero sadzapitiriza kutulutsa melanin melanin maselo, Kachiwiri, melanin sadzaona ndi maso a munthu pa khungu pamwamba, kuti tikwaniritse whitening kwenikweni.
Chachiwiri, niacinamide amatsimikizira kuti imakhala ndi zotsatira zabwino za saccharification, makamaka pambuyo pa 2015, mawu akuti "saccharification yozama kwambiri, matenda ambiri a thupi amasonyeza kuti ndi saccharification (maillard reaction), zinthu zopangidwa ndi saccharification ndi zofiirira, zimatha khungu limawoneka lakuda, kotero kukana phala kumathandizanso kuti whitening.ves, zowonjezera chakudya, zodzoladzola, etc.
M'mayesero olamulidwa a anthu a 20, malaya obwerezabwereza a nicotinamide pamagulu otsika (0.2%) anali othandizanso kuchepetsa chitetezo chamthupi chopangidwa ndi kuwala kwa dzuwa komwe kumatengera kuwala kwa dzuwa.0.2% ya ndende imakhala yothandiza, ndipo nthawi zambiri timagwiritsa ntchito nicotinamide yochokera kuzinthu zosamalira khungu nthawi zambiri zimakhala pamwamba pa 2%, ndende yabwino kwambiri ya 4% ~ 5%.Chifukwa chake perekani mankhwala a nicotinamide musanagwiritse ntchito zoteteza ku dzuwa
