2) Kubuza umusaruro wa melanin
VC n'ibiyikomokaho birashobora kubangamira tyrosinase, kugabanya igipimo cyo guhindura tyrosinase, no kugabanya umusaruro wa melanin. Usibye kubuza tyrosinase, VC irashobora kandi gukora nk'igabanuka rya melanin hamwe nigicuruzwa giciriritse cya synthesis ya melanin, dopaquinone, kugabanya umukara kugeza ibara kandi bigera ku ngaruka zera. Vitamine C ni ikintu cyiza kandi cyiza cyo kwera uruhu.
3) Izuba ryizuba
VC igira uruhare muri synthesis ya kolagen na mucopolysaccharide, itera gukira ibikomere, ikarinda izuba, kandi ikirinda urukurikirane rwasizwe nizuba ryinshi. Muri icyo gihe, vitamine C ifite antioxydants nziza kandi irashobora gufata no gutesha agaciro radicals yubusa mu ruhu, ikarinda kwangirika kwimirasire ya ultraviolet. Kubwibyo, vitamine C yitwa "izuba ryimbere". Nubwo idashobora gukurura cyangwa guhagarika imirasire ya ultraviolet, irashobora gutanga ingaruka zo gukingira kwangirika kwa ultraviolet muri dermis. Ingaruka zo kurinda izuba zo kongeramo VC zishingiye mubuhanga ~
4) Guteza imbere synthesis ya kolagen
Gutakaza kolagen na elastine birashobora gutuma uruhu rwacu rudakomera kandi rukagira ibihe byo gusaza nkumurongo mwiza.
Itandukaniro nyamukuru hagati ya kolagen na proteine isanzwe ni uko irimo hydroxyproline na hydroxylysine. Synthesis yaya acide yombi amine isaba uruhare rwa vitamine C.
Hydroxylation ya proline mugihe cyo guhuza kolagen isaba uruhare rwa vitamine C, bityo kubura vitamine C birinda synthesis isanzwe ya kolagen, biganisha ku guhuza imiyoboro ya selile.
5) Gusana inzitizi zangiritse kugirango uteze imbere gukira ibikomere
Vitamine C irashobora guteza imbere itandukaniro rya keratinocytes, igatera imbaraga za epidermal barrière, kandi igafasha kubaka icyorezo cya epidermal. Vitamine C rero igira ingaruka nziza cyane kuri bariyeri y'uruhu.
Iyi ni nayo mpamvu kimwe mu bimenyetso byo kubura iyi ntungamubiri ari ugukiza ibikomere.
6) Kurwanya inflammatory

Nyamara, iyi fomu irahinduka vuba kandi igahinduka idakora munsi yumuyaga, ubushyuhe, urumuri, cyangwa pH ikabije. Abahanga bashimangiye L-AA bayihuza na vitamine E na aside ferulic kugirango ikoreshwe mu kwisiga. Hariho ubundi buryo bwinshi bwa vitamine C, harimo aside aside ya 3-0 ya Ethyl, ascorbate glucoside, magnesium na sodium ascorbate fosifate, tetrahexyl decanol ascorbate, ascorbate tetraisopropylpalmitate, na palmate ya asorbate. Ibikomokaho ntabwo ari vitamine C yuzuye, ahubwo byahinduwe kugirango byongere imbaraga no kwihanganira molekile ya acide acorbike. Kubijyanye na efficacy, inyinshi murizo formula zifite amakuru avuguruzanya cyangwa zisaba ubundi bushakashatsi kugirango zemeze imikorere yazo. L-ascorbic aside, tetrahexyl decanol ascorbate, hamwe na tetraisopalmitate ya ascorbate ihagaze neza hamwe na vitamine E na aside ferulike ifite amakuru menshi ashyigikira ikoreshwa ryayo.
