Unokucinga ngayo njengeyona vitamin ibalaseleyo kwiglasi yakho yasekuseni ye-OJ, kodwa ivithamin C ikwabonelela ngeengenelo ezininzi xa isetyenziswa ngokwesihloko-kwaye amathuba okuba uyibonile iphuma kwiimveliso zokhathalelo lolusu ngakumbi nangakumbi. Nangona isithako kungesiso umntwana omtsha kwibhloko, ngokuqinisekileyo yenye yezona zidumileyo okwangoku. UTed Lain, MD, ugqirha wesikhumba eAustin, TX, uchaza oku ekuqondeni okukhulayo kwento eyonakalisa ulusu lwethu ... kunye nendlela ivithamin C enokunceda ngayo. "Kukho ukuphindaphinda ekuthandeni iimveliso ze vithamin C ngenxa yokwanda kolwazi lweziphumo zelanga kunye nongcoliseko kulusu, kunye nezibonelelo zokukhusela izithako," utshilo. (Okuninzi kuloo ngomzuzu.)

Ke yintoni yonke le hype malunga nayo? Ewe, amaxwebhu esikhumba ayayithanda ngenxa yobuninzi beempawu ezichasene nokuguga, isenza isisombululo esifanelekileyo kuzo zonke iintlobo zokuxhalaba. Apha, ukuhla kweengcali kule VIP vitamin.

Yisongelo esichasene nokwaluphala kathathu.

Okokuqala nokuphambili, ivithamin C yintsholongwane enamandla. "Ukubonakaliswa kwimitha ye-UV kunye nokungcola kudala iintlobo ze-oksijini ezisebenzayo-okanye i-ROS-kwisikhumba, ezonakalisa i-DNA yeeseli zakho kwaye iholele kuzo zombini iimpawu zokuguga kunye nomhlaza wolusu," kuchaza uDkt Lain. "IVithamin C isebenza ukuphelisa ezo zimoshakalayo iROS, ikhusela iiseli zolusu lwakho." (FYI, oku kuyenzeka nokuba ukhuthele kakhulu malunga nesicelo se-sunscreen, yiyo loo nto nabani na kwaye wonke umntu enokuzuza ngokusebenzisa i-antioxidants ye-topical.)

Ke, kukho ubuchule bayo obuqaqambileyo. I-Vitamin C-aka ascorbic acid-yinto encinci enokunceda ekunyibilikiseni iiseli zolusu ezinombala ocacileyo, icacisa i-New York City dermatologist u-Ellen Marmur, MD nangakumbi, iyasebenza ukunceda ukuthintela i-tyrosinase, i-enzyme ebaluleke kakhulu kwimveliso entsha sakhi sombala; i-tyrosinase encinci ilingana namanqaku amnyama ambalwa. Uguqulo: I-Vitamin C zombini inceda ukucima amabala asele ekhona kwaye ithintele ukwakheka kwezinto ezintsha, iqinisekisa ukuba ulusu lwakho luhlala lungenabala. (Njengokuba usebenzisa i-sunscreen rhoqo, kunjalo.)

Kwaye ekugqibeleni, masithethe ngemveliso ye-collagen. Ngokusebenza njenge-antioxidant, igcina i-ROS enesifo ekuphuleni zombini i-collagen kunye ne-elastin (egcina ulusu luqinile). Olunye uphononongo luye lwabonisa ukuba ivithamin C ivuselela i-fibroblasts, iiseli ezenza i-collagen, uphawula u-Emily Arch, MD, ugqirha wesikhumba kwiDermatology + Aesthetics eChicago. (Kwaye i-FYI, akukaze kusekuqaleni ukuqala ukukhusela i-collagen kulusu lwakho.)

Ukulungiselela ezi njongo zokwakha i-collagen, ukutya kwakho kubalulekile. Ngokophononongo olupapashwe kwi Ijenali yaseMelika yeZondlo zeklinikhi, Ukutya okuphezulu kwe-vitamin C kwakudityaniswa nolusu olungenamibimbi. I-vitamin C enganyangekiyo inceda ngakumbi kwimveliso ye-collagen kuneenguqulelo ezikwimixholo, utshilo uGqirha Arch, kuba iyakwazi ukufikelela kulwalwa olunzulu lolusu kwiderm. Cinga ngesi esinye isizathu sokulayisha kwiziqhamo ezityebileyo ze-vitamin C kunye nemifuno efana nepepile ebomvu, amahlumela aseBrussels, kunye namaqunube. (Ngakumbi ngaloo nto apha: Imithombo ye-8 eyothusayo yeZondlo)

Gcina nje ukhumbule ukuba iyaziwa ngokungazinzi.

Eyona ngxaki iphambili apha kukuba ivithamin C imalunga nje nokungazinzanga njengokuba inamandla. Ukuvezwa komoya kunye nokukhanya kwelanga kunokukhawuleza ukwenza ukuba isithako singasebenzi, ilumkisa ugqirha wesikhumba weSixeko saseNew York uGervaise Gerstner, M.D. Khangela iimveliso ezigcinwe kwiibhotile ezikhanyayo kwaye zigcinwe kwindawo epholileyo, eyomileyo, uyongezelela.

Unokufuna kwakhona ifomula edibanisa ivithamini kunye ne-asidi ye-ferulic, enye i-antioxidant enamandla: "I-asidi ye-Ferulic ayisebenzi nje kuphela ukuzinzisa i-vitamin C kodwa ikwanyusa kwaye inyuse iziphumo zayo," ucacisa uGqirha Lain. I-SkinCeuticals C E Ferulic (i-$ 166; i-skinceuticals.com) iyintandokazi yederm yexesha elide. (Inxulumene: Iimveliso zokhathalelo lolusu kwiDermatologists Uthando)

Kukwakho nodidi olutsha lomgubo lwevithamin C, ekumele ukuba ixutywe nayo nayiphi na into yokuthambisa, i-serum, okanye isikhuseli elangeni; kwithiyori, ezi zizinzile ngakumbi kuba mancinci amathuba okuba badibane nokukhanya.

Kufuneka uyisebenzise kanye ngosuku.

Ngokuqinisekileyo akukho kunqongophala kweemveliso ezisisiseko sevithamini C phaya; sithetha yonke into ukusuka kwi-serum ukuya kwii-mask ukuya kwi-mists ... kwaye yonke into ephakathi. Okwangoku, ukufumana eyona buck yakho, eyona ukubheja kwakho kuyiserum. Ezi fomyula azipheleli nje ekuqulatheni ugxininiso oluphezulu lwesithako esisebenzayo, zikwabekwe ngokulula phantsi kwezinye iimveliso, ubonisa uGqr Gerstner.

Inye ukuzama: Imifanekiso yoLusu lweVital C yokuHanjiswa kweSerum yokuGuga ($ 64; imageskincare.com). Faka isicelo samaconsi ambalwa kubo bonke emva kokucoca ubuso bakho, phambi kwescreen-ntsasa nganye. Kwaye ukuba uzama ukonga imali (kuba masijongane nayo, iimveliso zevithamini C zihlala zibiza ixabiso), uGqr.Arch uphawula ukuba ungaphuma ekusebenziseni imveliso yeevithamin C yonke imihla. "Ukuba uyisebenzisa ekukhanyiseni kungcono usebenzise yonke imihla, kodwa kwisiphumo sokulwa ne-antioxidant, ungayisebenzisa yonke imihla ukusukela ukuba ibisesikhumbeni, ibonakalisiwe ukuba iyasebenza ukuya kuthi ga kwiiyure ezingama-72," uyacacisa.

Njengaso nasiphi na isithako esinamandla sokukhathalela ulusu, sinakho ukubangela ukucaphuka, ngakumbi ukuba ulusu lwakho lunobuntununtunu ekuqaleni. Amaxesha okuqala kufuneka aqale ngokuwasebenzisa amaxesha ambalwa kuphela ngeveki, emva koko ngokuthe ngcembe anyuse amaxesha okuba ulusu lwakho luyakunyamezela.
