Ivithamini C(VC) sisithako esiqhelekileyo sokwenza mhlophe kwizithambiso, kodwa kukho amarhe okuba ukusebenzisa izinto zokuthambisa ezine-VC emini akuyi kuyenza mhlophe nje kuphela ulusu, kodwa kuya kwenza ulusu lube mnyama; abanye abantu baxhalabile kukuba ukusebenzisa iimveliso zokhathalelo lolusu ezine-VC kunye ne-nicotinamide ngaxeshanye kuya kubangela i-allergies. Ukusetyenziswa kwexesha elide kwezithambiso ezine-VC kuya kwenza ulusu lube buthathaka. Enyanisweni, konke oku kukungaqondani malunga nezithambiso ezine-VC.
Intsomi 1: Ukuyisebenzisa emini kuya kuyenza mnyama ulusu lwakho
I-VC, ekwaziwa ngokuba yi-L-ascorbic acid, yi-antioxidant yendalo enokusetyenziselwa ukunyanga nokuthintela ukutsha lilanga lolusu. Kwizinto zokuthambisa, i-VC inokucothisa inkqubo yokwenziwa kwe-melanin efana ne-dopaquinone ngokusebenzisana nee-ion ze-copper kwindawo esebenzayo ye-tyrosinase, ngaloo ndlela iphazamisane nokuveliswa kwe-melanin kwaye ifezekise isiphumo sokwenza mhlophe nokususa amabala.
Ukwakheka kwe-melanin kunxulumene neempendulo ze-oxidation. Njenge-antioxidant eqhelekileyo,VCinokuthintela ukusabela kwe-oxidation, ivelise isiphumo esithile sokuba mhlophe, iphucule amandla okulungisa nokuvuselela ulusu, ilibazise ukuguga, kwaye inciphise umonakalo we-ultraviolet kulusu. I-VC ayizinzanga kwaye i-oxidation ilula emoyeni kwaye ilahlekelwa ngumsebenzi wayo we-antioxidant. Imitha ye-Ultraviolet iya kukhawulezisa inkqubo ye-oxidation. Ke ngoko, kuyacetyiswa ukuba usebenziseIzithambiso ezine-VCebusuku okanye kude nokukhanya. Nangona ukusebenzisa izithambiso ezine-VC emini kusenokungaphumeleli iziphumo ezilungileyo, akuyi kubangela ukuba ulusu lube mnyama. Ukuba usebenzisa iimveliso zokhathalelo lolusu ezine-VC emini, kufuneka uzikhusele elangeni, njengokunxiba impahla enemikhono emide, umnqwazi, kunye ne-parasol. Imithombo yokukhanya eyenziweyo efana nezibane ze-incandescent, izibane ze-fluorescent, kunye nezibane ze-LED, ngokungafaniyo nemisebe ye-ultraviolet, ayichaphazeli i-VC, ngoko akukho mfuneko yokukhathazeka malunga nokukhanya okukhutshwa zizikrini zefowuni eziphathwayo okuchaphazela ukusebenza kwezithambiso ezine-VC.
Intsomi 2: Ukusetyenziswa ixesha elide kuya kwenza ulusu lube buthathaka
Oko sidla ngokukubiza ngokuba"ukuncitshiswa kolusu"eneneni kukuncipha kwe-stratum corneum. Isizathu esibalulekileyo sokuncitshiswa kwe-stratum corneum kukuba iiseli ezikwi-basal layer zonakele kwaye azikwazi ukwahlukana nokuzala ngokuqhelekileyo, kwaye umjikelo wokuqala we-metabolic uyatshatyalaliswa.
Nangona i-VC ine-asidi, umxholo we-VC kwizinto zokuthambisa awanelanga ukubangela ulusu umonakalo. I-VC ayizukwenza i-stratum corneum ibe ncinci, kodwa abantu abane-stratum corneum encinci badla ngokuba nolusu olubuthathaka ngakumbi. Ke ngoko, xa usebenzisa iimveliso zokucoca eziqulethe i-VC, kufuneka uqale uyizame kwiindawo ezinje ngasemva kweendlebe ukuze ujonge ukuba kukho naziphi na izinto ezibangela ukuba umntu angabi naso i-allergies.
Izithambisokufuneka zisetyenziswe ngokulinganisela. Ukuba uzisebenzisa ngokugqithisileyo ukufuna ukwenza mhlophe, uya kulahlekelwa kakhulu kunokuba uzifumana. Ngokuphathelele i-VC, imfuno yomzimba womntu kunye nokufunxwa kwe-VC kulinganiselwe. I-VC edlula iindawo ezifunekayo zomzimba womntu ayizukufunxwa nje kuphela, kodwa inokubangela urhudo kwaye ichaphazele nokusebenza kokubopha. Ke ngoko, izinto zokuthambisa ezine-VC akufuneki zisetyenziswe ngokugqithisileyo.
