Abanye abantu basetyhini bajongana neemeko zolusu. Abanye bafuna ukukhanyisa kunye nokuhlaziya ulusu lwabo. Inzululwazi ye-vitamin C iyityhila ngokulula ikhanyisa ulusu, ikakhulu ngokunciphisa inani leeseli zesikhumba se-melanin. Uphando lubonisa unyango lwezihloko kunye nevithamini C okanye ezinye izinto, ngokudityaniswa nemithombo yokutya, isebenza ngakumbi kunezongezelelo zomlomo.
Ngaba ivithamin C ikhanyisa ulusu?
Ngokwe-2007 yoqwalaselo ku Unyango lweDermatologic , ikwimo elungileyo kunye noxinaniso, ivithamin C, okanye i-L-ascorbic acid, 'yeyona arhente isebenzayo yokuphelisa ibala,' kwaye ivithamin E iphucula ukusebenza kwe-vitamin C kulusu. Inqaku le-2013 kwi I-Indian Dermatology kwiJenali ye-Intanethi Ukwaphawula ivithamin C sisikhanyisi esisebenzayo kwaye sinceda ukugcina ulusu lwakho lusempilweni.
Amanqaku afanelekileyo- Indlela yokukhanyisa umbala weSikhumba kwiintsuku ezi-3
- Indima yeVitamin C kuKhathalelo lweSikhumba
- Ngaba iiceramides eziphambili ekunakekeleni ulusu?
Isifundo esincinci esichaziweyo kwi-2004 kwi Ijenali yaMazwe ngaMazwe yeDermatology ifumene ivithamin C efakwe iiveki ezili-16 isebenze ekukhanyeni ulusu lwezigulana ezine imelasma . Oku kwafaniswa nokusebenza kwehydroquinone, imveliso ende ekhanyisa ulusu. Nangona ihydroquinone yayisebenza ngakumbi ekukhanyeni kwesikhumba kune-vitamin C (iipesenti ezingama-93 xa ithelekiswa neepesenti ezingama-63), ivithamin C yayineziphumo ebezingalindelekanga ezimbalwa kunehydroquinone (iipesenti ezi-6 xa ithelekiswa neepesenti ezingama-69).
Inkqubo ye- Ijenali yeDermatology yeklinikhi kunye neAesthetic Ukwaphawula ukuba ivithamin C iyasebenza ekunyangeni iimeko zesikhumba ezixinzelelweyo apho abantu abanesikhumba esimnyama bathambekele ngakumbi.
Uvithamini C ukhanyisa njani uLusu
Uphengululo olwenziwe yi IZiko leLinus Pauling waseOregon State University uthi ukuguga, ukubekwa elangeni, ukutshaya, kunye nezinye izinto ezingcolisayo kunciphisa umxholo weevithamin C yolusu kwaye kubangele ukuba buthuntu kunye ne-hyperpigmented. I-vitamin C eyaneleyo ekudleni kwakho okanye ifakwe kwisikhumba sakho inceda ukuyigcina ikhanya, ikhanya kwaye ikhanya, ngakumbi njengoko uneminyaka yobudala.
I-Vitamin C ikhona kuwo onke amacandelo esikhumba. Ngokusekwe kwinto eyaziwayo ngezenzo zayo kulusu, ivithamin C inokunciphisa iimpawu zokwaluphala, ikhanyise isikhumba esiqhelekileyo kunye neemeko zolusu ezixubileyo, kwaye ikhanyise ukubonakala kwayo ngeendlela ezininzi:
- Ubungakanani beeseli zesikhumba se-melanin (melanocytes) zenza umbala wombala wolusu. IVitamin C inciphisa ukuveliswa kwe-melanin ngokuthi iphazamise isenzo se tyrosinase -I-enzyme yokuqala kwindlela eguqula i-amino acid tyrosine iye kwi-melanin. Kukho i-melanin encinci yokuhambisa kwinqanaba eliphezulu leeseli zolusu, ke ulusu luyakhanya.
- Yonyusa ivithamin E kwaye glutathione (i-tri-amino acid antioxidant) eluswini, enceda ulusu ukuba lwenze ukukhanya okungaphezulu, i-pheomelanin etyheli ngokungafaniyo ne-eumelanin emnyama. UVitamin C uphinde uvuselele ivithamin E; ke ngoko, iivithamini ezimbini zisebenza ngokuvumelanisa.
- Kuyanceda ukwahlulwa kweseli kwesikhumba, ukuvuselelwa, kunye nengeniso ukuze iiseli ezintsha, ezincinci, ezikhanyayo kunye nezikhanyayo zibonakale kumphezulu wolusu.
- Njenge-antioxidant enamandla, ithomalalisa ii-radicals zasimahla ezonakalisa iiseli, ngenxa yoko inciphisa iziphumo zokuguga kwendalo kunye nokonakaliswa lilanga okubangela i-hyperpigmentation, ukugcina ulusu lukhangeleka lusemncinci kwaye lukhanya
UVitamin C uneendima ezininzi emzimbeni, kodwa umzimba wakho awunako ukwenza okanye ukugcina ivithamini enyibilikayo emanzini, ngokwe Iphepha leenkcukacha zeZiko lezeMpilo .

Ukuzama ukoyisa isithintelo sozinzo, abanye abavelisi basebenzisa iziphumo ezizinzileyo ze-L-ascorbic acid, endaweni yoko, kwiimveliso zabo zolusu. Iziphumo ezivela kuVitamin C kwiimveliso ezikhoyo zibandakanya:
- Magnesium ascorbyl phosphate
- Isodium ascorbyl phosphate
- I-Ascorbyl glucoside
- I-Ascorbyl palmitate
Olunye uphononongo lwe-magnesium ascorbyl phosphate, esona siphumo sizinzileyo, sapapashwa kwi Ijenali yeAmerican Academy yeDermatology .
