Vitamine C(VC) ni ikintu gikunze gukoreshwa mu kwisiga, ariko hari ibihuha bivuga ko gukoresha amavuta yo kwisiga arimo VC ku manywa bitazakuraho uruhu gusa, ahubwo bizanatuma uruhu rwijima; hari abantu bafite impungenge ko gukoresha imiti yo kwisiga irimo VC na nicotinamide icyarimwe bizatera allergie. Gukoresha amavuta yo kwisiga arimo VC igihe kirekire bizatuma uruhu rurushaho kuba rugufi. Mu by'ukuri, ibi byose ni ukutumvikana ku bijyanye n'amavuta yo kwisiga arimo VC.
Ikinyoma cya 1: Kuyikoresha ku manywa bizahindura uruhu rwawe umwijima
VC, izwi kandi nka aside L-ascorbic, ni antioxydant karemano ishobora gukoreshwa mu kuvura no gukumira ubushyuhe bw'izuba ku ruhu. Mu bijyanye no kwisiga, VC ishobora kugabanya umuvuduko wo gukora melanin nka dopaquinone ikoresheje iyoni z'umuringa aho tyrosinase ikora, bityo ikabangamira ikorwa rya melanin kandi ikagera ku ngaruka zo kwera no gukuraho uduce duto tw'uruhu.
Ikorwa rya melanin rifitanye isano n'ingaruka za ogisijeni. Nk'umuti usanzwe urwanya ogisijeni,VCishobora kubuza ibikorwa byo kuvura uruhu, igatanga ingaruka zimwe na zimwe zo kwera, ikongera ubushobozi bwo gusana no kuvugurura uruhu, igatinda gusaza, kandi ikagabanya kwangirika kwa ultraviolet ku ruhu. VC ntabwo ihindagurika kandi ihita ihinduka mu kirere kandi igatakaza imikorere yayo yo kurwanya uburwayi. Imirasire ya ultraviolet izihutisha inzira yo kuvura uruhu. Kubwibyo, ni byiza gukoreshaIbikoresho byo kwisiga birimo VCnijoro cyangwa kure y'urumuri. Nubwo gukoresha amavuta yo kwisiga arimo VC ku manywa bishobora kutazatanga umusaruro mwiza, ntibizatuma uruhu rwijima. Niba ukoresha ibikoresho byo kwisiga birimo VC ku manywa, ugomba kwirinda izuba, nko kwambara imyenda y'amaboko maremare, ingofero, n'umusatsi. Amatara y'ubukorano nka amatara y'ubukonje, amatara y'urumuri, n'amatara ya LED, bitandukanye n'imirasire ya ultraviolet, ntabwo agira ingaruka kuri VC, bityo nta mpamvu yo guhangayikishwa n'urumuri rutangwa na ecran za telefoni zigendanwa rugira ingaruka ku mikorere y'amavuta yo kwisiga arimo VC.
Ikinyoma cya 2: Gukoresha igihe kirekire bizatuma uruhu rurushaho kuba ruto
Icyo dukunze kwita"kugabanya uruhu"Mu by’ukuri ni ukugabanuka kwa stratum corneum. Impamvu nyamukuru ituma stratum corneum igabanuka ni uko uturemangingo two mu gice cy’ibanze twangiritse kandi tudashobora kwigabanya no kororoka mu buryo busanzwe, maze imikorere y’umubiri ya mbere ikarangirika.
Nubwo VC ifite aside, VC irimo amavuta yo kwisiga ntabwo ihagije kugira ngo igire ingaruka mbi ku ruhu. VC ntabwo izatuma stratum corneum iba nto, ariko abantu bafite stratum corneum iba ntoya akenshi baba bafite uruhu rworoshye cyane. Kubwibyo, iyo ukoresha imiti igabanya uruhu irimo VC, ugomba kubanza kuyigerageza ahantu nko inyuma y'amatwi kugira ngo urebe niba hari allergie.
Ibikoresho byo kwisigaikwiye gukoreshwa mu rugero. Iyo uyikoresheje cyane mu gushaka umweru, akenshi uzatakaza byinshi kuruta ibyo winjiza. Ku bijyanye na VC, umubiri w'umuntu ukeneye kandi ukamuramo VC ni bike. VC irenze ibice by'umubiri w'umuntu ntabwo izayinjiramo gusa, ahubwo ishobora no gutera impiswi byoroshye ndetse ikagira ingaruka ku mikorere y'amaraso. Kubwibyo, amavuta yo kwisiga arimo VC ntagomba gukoreshwa cyane.
