Niacinamide (Panacea a cikin duniyar kula da fata)

Niacinamide, wanda kuma aka fi sani da bitamin B3 (VB3), shine nau'in niacin na ilimin halitta kuma ana samunsa sosai a cikin dabbobi da tsirrai iri-iri. Har ila yau, mahimmanci ne mai mahimmanci na masu haɗin gwiwar NADH (nicotinamide adenine dinucleotide) da NADPH (nicotinamide adenine dinucleotide phosphate). Tare da rage NADH da NADPH, suna aiki azaman coenzymes a cikin fiye da halayen 40 biochemical kuma suna aiki azaman antioxidants.

A asibiti, ana amfani da shi musamman don rigakafi da magance pellagra, stomatitis, glossitis da sauran cututtuka masu alaƙa.

Nicotinamide na iya rage-kayyade jigilar melanosomes daga melanocytes zuwa keratinocytes ba tare da hana ayyukan tyrosinase ko haɓakar tantanin halitta ba, don haka yana shafar launin fata. Hakanan zai iya tsoma baki tare da hulɗar tsakanin keratinocytes da melanocytes. Tashoshin siginar tantanin halitta tsakanin sel suna rage samar da melanin. A gefe guda, nicotinamide na iya yin aiki akan rigar da aka samar da melanin kuma ya rage canzawa zuwa sel.

Wani ra'ayi shi ne cewa nicotinamide kuma yana da aikin anti-glycation, wanda zai iya tsoma launin rawaya na furotin bayan glycation, wanda zai taimaka wajen inganta launin fata na fuskoki masu launin kayan lambu har ma da "mata masu launin rawaya".

Gyaran aikin shingen fata na Niacinamide yana nunawa ta fuskoki biyu:

① Inganta kira na ceramide a cikin fata;

② Haɓaka bambance-bambancen ƙwayoyin keratin;
Yin amfani da nicotinamide na waje na iya ƙara yawan adadin fatty acid da ceramides a cikin fata, tada microcirculation a cikin dermis, da hana asarar danshi na fata.

Hakanan yana haɓaka haɓakar furotin (kamar keratin), yana haɓaka matakan NADPH na ciki (nicotinamide adenine dinucleotide phosphate), kuma yana haɓaka bambancin keratinocyte.
