I-Vitamin C(VC) isithako esivamile sokwenza mhlophe ezimonyweni, kodwa kukhona amahemuhemu okuthi ukusebenzisa izimonyo ezine-VC emini ngeke nje kuhluleke ukwenza mhlophe isikhumba, kodwa kuzophinde kufiphaze isikhumba; abanye abantu bakhathazekile ngokuthi ukusebenzisa imikhiqizo yokunakekela isikhumba equkethe i-VC kanye ne-nicotinamide ngesikhathi esisodwa kuzobangela ukungezwani komzimba. Ukusetshenziswa isikhathi eside kwezimonyo ezine-VC kuzokwenza isikhumba sibe sincane. Eqinisweni, konke lokhu kungukungaqondi kahle ngezimonyo ezine-VC.

Ezimonyweni, i-VC inganciphisa inqubo yokwenziwa kwe-melanin njenge-dopaquinone ngokusebenzisana nama-ion ethusi endaweni esebenzayo ye-tyrosinase, ngaleyo ndlela iphazamise ukukhiqizwa kwe-melanin futhi ifinyelele umphumela wokwenza mhlophe nokususa amabala.
Ukwakheka kwe-melanin kuhlobene nokusabela kwe-oxidation. Njenge-antioxidant evamile,VCingavimbela ukusabela kwe-oxidation, ikhiqize umphumela othile wokwenza mhlophe, ithuthukise amakhono okulungisa nokuvuselela isikhumba, ibambezele ukuguga, futhi inciphise umonakalo we-ultraviolet esikhumbeni. I-VC ayizinzile futhi i-oxidation kalula emoyeni futhi ilahlekelwa umsebenzi wayo we-antioxidant. Imisebe ye-Ultraviolet izosheshisa inqubo ye-oxidation. Ngakho-ke, kunconywa ukusebenzisaIzimonyo eziqukethe i-VCebusuku noma kude nokukhanya. Nakuba ukusetshenziswa kwezimonyo eziqukethe i-VC emini kungase kungafezi imiphumela emihle, ngeke kubangele ukuba isikhumba sibe mnyama.

Inganekwane 2: Ukusetshenziswa isikhathi eside kuzokwenza isikhumba sibe sincane
Lokho esivame ukukubiza ngokuthi"ukuncipha kwesikhumba"empeleni kuwukuncipha kwe-stratum corneum. Isizathu esibalulekile sokuncipha kwe-stratum corneum ukuthi amaseli asengqimbeni ephansi alimele futhi awakwazi ukwahlukana nokuzala ngokujwayelekile, futhi umjikelezo wokuqala we-metabolic uyabhujiswa.
Nakuba i-VC ine-asidi, okuqukethwe yi-VC ezimonyweni akwanele ukubangela umonakalo esikhumbeni. I-VC ngeke yenze i-stratum corneum ibe ncane, kodwa abantu abane-stratum corneum encane bavame ukuba nesikhumba esibucayi kakhulu. Ngakho-ke, uma usebenzisa imikhiqizo yokwenza mhlophe equkethe i-VC, kufanele uqale uyizame ezindaweni ezinjengangemuva kwezindlebe ukuze uhlole ukuthi kukhona yini ukungezwani komzimba.
Izimonyokufanele zisetshenziswe ngokulinganisela. Uma uzisebenzisa ngokweqile ukuze ufune ukwenza mhlophe, uzovame ukulahlekelwa okungaphezu kwalokho okutholayo.
