Ivithamini C(VC) iyisithako esivamile sokwenza mhlophe kwezimonyo, kodwa kukhona amahemuhemu okuthi ukusebenzisa izimonyo ezine-VC phakathi nosuku ngeke nje kuhluleke ukwenza mhlophe isikhumba, kodwa futhi kuzofiphaza isikhumba;abanye abantu bakhathazekile ngokuthi ukusebenzisa imikhiqizo yokunakekelwa kwesikhumba equkethe i-VC ne-nicotinamide ngesikhathi esifanayo kuzodala ukungezwani komzimba nezinto ezithile.Ukusetshenziswa isikhathi eside kwezimonyo ezine-VC kuzokwenza isikhumba sibe mncane.Eqinisweni, konke lokhu ukungaqondi kahle mayelana nezimonyo eziqukethe i-VC.
Inganekwane 1: Ukuyisebenzisa emini kuzokwenza isikhumba sakho sibe mnyama
I-VC, eyaziwa nangokuthi i-L-ascorbic acid, iyi-antioxidant yemvelo engasetshenziswa ukwelapha nokuvimbela ukushiswa yilanga kwesikhumba.Kwezimonyo, i-VC inganciphisa inqubo yokwenziwa kwe-melanin njenge-dopaquinone ngokusebenzisana nama-ion ethusi endaweni esebenzayo ye-tyrosinase, ngaleyo ndlela iphazamise ukukhiqizwa kwe-melanin futhi izuze umphumela wokuba mhlophe nokususa ama-freckles.
Ukwakheka kwe-melanin kuhlobene nokusabela kwe-oxidation.Njenge-antioxidant evamile,VCingavimbela ukusabela kwe-oxidation, ikhiqize umphumela othize wokuba mhlophe, ithuthukise ukukhanda isikhumba kanye namakhono okuvuselela, ibambezele ukuguga, futhi inciphise ukulimala kwe-ultraviolet esikhumbeni.I-VC ayizinzile futhi i-oxidized 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 ezine-VC phakathi nosuku kungase kungafinyeleli imiphumela emihle, ngeke kubangele ukuba isikhumba sibe mnyama.Uma usebenzisa izinto zokunakekela isikhumba ezine-VC phakathi nosuku, kufanele uzivikele elangeni, njengokugqoka izingubo ezinemikhono emide, isigqoko kanye ne-parasol.Imithombo yokukhanya yokwenziwa efana nezibani ze-incandescent, izibani ze-fluorescent, nezibani ze-LED, ngokungafani nemisebe ye-ultraviolet, ayithinti i-VC, ngakho-ke asikho isidingo sokukhathazeka ngokukhanya okukhishwa izikrini zefoni ephathekayo ezithinta ukusebenza kwezimonyo ezine-VC.
Inganekwane yesi-2: Ukusetshenziswa isikhathi eside kuzokwenza isikhumba sibe mncane
Esivame ukubhekisela kukho“ukuncipha kwesikhumba”empeleni kuwukuncipha kwe-stratum corneum.Isizathu esibalulekile sokuncipha kwe-stratum corneum ukuthi amaseli kungqimba lwe-basal alimele futhi awakwazi ukuhlukana futhi akhiqize ngokujwayelekile, futhi umjikelezo wokuqala we-metabolic uyabhujiswa.
Nakuba i-VC ine-acidic, okuqukethwe kwe-VC ezimonyoni akwanele ukubangela ukulimala esikhumbeni.I-VC ngeke yenze i-stratum corneum ibe mncane, kodwa abantu abane-stratum corneum ezacile ngokuvamile banesikhumba esizwela kakhulu.Ngakho-ke, uma usebenzisa imikhiqizo emhlophe equkethe i-VC, kufanele uqale uyizame ezindaweni ezifana nangemuva kwezindlebe ukuze uhlole ukuthi kukhona yini ukungezwani komzimba.
Izimonyokufanele isetshenziswe ngokulinganisela.Uma uzisebenzisa ngokweqile ekuphishekeleni ukwenza zibe mhlophe, ngokuvamile uzolahlekelwa okungaphezu kwalokho okuzuzayo.Ngokuqondene ne-VC, isidingo somzimba womuntu nokumuncwa kwe-VC kunomkhawulo.I-VC edlula izingxenye ezidingekayo zomzimba womuntu ngeke nje imunceke, kodwa futhi ingabangela kalula isifo sohudo futhi ithinte ngisho nokusebenza kwe-coagulation.Ngakho-ke, izimonyo eziqukethe i-VC akufanele zisetshenziswe ngokweqile.
