Vitamine C..abantu bamwe bafite impungenge ko gukoresha ibicuruzwa byita kuruhu birimo VC na nicotinamide icyarimwe bizatera allergie.Gukoresha igihe kirekire kwisiga VC irimo kwisiga bizatuma uruhu rworoha.Mubyukuri, ibyo byose ni ukutumvikana kubyerekeye kwisiga VC irimo.
Ikinyoma cya 1: Kubikoresha kumanywa bizaguhindura uruhu
VC, izwi kandi nka L-ascorbic aside, ni antioxydants isanzwe ishobora gukoreshwa mu kuvura no kwirinda izuba ry’uruhu.Mu kwisiga, VC irashobora kugabanya umuvuduko wa synthesis ya melanin nka dopaquinone ikorana na ion z'umuringa ahakorerwa tyrosinase, bityo bikabangamira umusaruro wa melanin kandi bikagera ku ngaruka zo kwera no gukuraho ibibyimba.
Imiterere ya melanin ifitanye isano na okiside reaction.Nka antioxydants isanzwe,VCIrashobora guhagarika imyuka ya okiside, ikabyara ingaruka zimwe zo kwera, kongera imbaraga zo gusana uruhu nubushobozi bushya, gutinda gusaza, no kugabanya kwangirika kwa ultraviolet kuruhu.VC ntigihungabana kandi irashobora guhumeka neza mu kirere ikabura ibikorwa bya antioxydeant.Imirasire ya Ultraviolet izihutisha inzira ya okiside.Kubwibyo, birasabwa gukoreshaAmavuta yo kwisiga arimo VCnijoro cyangwa kure y'umucyo.Nubwo gukoresha amavuta yo kwisiga arimo VC kumunsi bidashobora kugera kubisubizo byiza, ntabwo bizatera uruhu kwijimye.Niba ukoresha ibicuruzwa byita ku ruhu birimo VC ku manywa, ugomba kwirinda izuba, nko kwambara imyenda miremire, ingofero, na parasol.Inkomoko yumucyo nkamatara yaka, amatara ya fluorescent, namatara ya LED, bitandukanye nimirasire ya ultraviolet, ntabwo bigira ingaruka kuri VC, kubwibyo rero nta mpamvu yo guhangayikishwa numucyo utangwa na ecran ya terefone igendanwa bigira ingaruka kumikorere ya cosmetike irimo VC.
Ikinyoma cya 2: Gukoresha igihe kirekire bizatuma uruhu rworoha
Ibyo dukunze kuvuga nka“uruhu”ni mubyukuri kunanuka kwa stratum corneum.Impamvu yingenzi yo kunanuka kwa stratum corneum nuko ingirabuzimafatizo ziri murwego rwibanze zangiritse kandi ntizishobora kugabana no kubyara bisanzwe, kandi ukwezi kwa metabolike kwambere kurimbuka.
Nubwo VC irimo aside, ibirimo VC mubisiga ntibihagije kugirango byangize uruhu.VC ntabwo izakora stratum corneum yoroheje, ariko abantu bafite stratum corneum yoroheje bafite uruhu rworoshye.Kubwibyo, mugihe ukoresheje VC irimo ibicuruzwa byera, ugomba kubanza kubigerageza ahantu nko inyuma yamatwi kugirango urebe niba hari allergie.
Amavuta yo kwisigabigomba gukoreshwa mu rugero.Niba ubikoresha cyane mugukurikirana umweru, uzahomba byinshi birenze ibyo wungutse.Kubijyanye na VC, ibyifuzo byumubiri wumuntu no kwinjiza VC ni bike.VC irenze ibice bikenewe byumubiri wumuntu ntabwo izakirwa gusa, ahubwo irashobora no gutera impiswi byoroshye ndetse ikagira ingaruka kumikorere ya coagulation.Kubwibyo, VC irimo kwisiga ntigomba gukoreshwa cyane.
