U ka e nka e le vithamine e hlahelletseng ka khalaseng ea hau ea hoseng ea OJ, empa vithamine C e boetse e fana ka melemo e mengata ha e sebelisoa ka holimo-'me ho na le menyetla ea hore u e bone e hlaha lihlahisoa tsa hau tsa tlhokomelo ea letlalo haholoanyane. Le ha sesebelisoa e se ngoana e mocha, ke e 'ngoe ea tse ratoang haholo hajoale. Ted Lain, MD, dermatologist ho la Austin, TX, o re sena ke kutloisiso e ntseng e hola ea se senyang letlalo la rona ... le hore na vithamine C e ka thusa joang. O re: "Ho na le ts'ebetso ea ho tsebahala ha lihlahisoa tsa vithamine C ka lebaka la tlhokomeliso e eketsehileng ea liphello tsa letsatsi le tšilafalo letlalong, le melemo ea tšireletso ea motsoako." (Ho feta ka seo ka motsotso.)


Joale hype eohle e mabapi le eng? Ha e le hantle, matlalo a letlalo aa e rata ka lebaka la litšoaneleho tsa eona tse ngata tse khahlanong le botsofali, e leng se etsang hore e be tharollo e bohlale bakeng sa mefuta eohle ea mathata a letlalo. Mona, litsebi li fokotseha ka vithamine ena ea VIP.

Ke tšokelo e khahlano le botsofali ka makhetlo a mararo.

Pele ho tsohle, vithamine C ke antioxidant e matla. Dr. Lain o re: "Ho pepesehela mahlaseli a UV le tšilafalo ho hlahisa mefuta ea oksijene e sebetsang kapa ROS-letlalong, e ka senyang lisele tsa hau tsa DNA mme ea lebisa ho matšoao a botsofali le mofetše oa letlalo." "Vithamine C e sebetsa ho fokotsa ROS e senyang, e sireletsa lisele tsa letlalo." (FYI, sena se etsahala leha o le mafolofolo haholo mabapi le ts'ebeliso ea setlolo se sireletsang letsatsi letsatsing, ke ka lebaka leo mang kapa mang le motho e mong le e mong a ka ruang molemo ka ho sebelisa li-antioxidants tsa lihlooho.)

Joale, ho na le bokhoni ba eona bo khanyang. Vithamine C-aka ascorbic acid-ke setlolo se bobebe se ka thusang ho qhala lisele tsa letlalo tse nang le pherekano kapa tse soeufetseng, ho hlalosa dermatologist oa New York City Ellen Marmur, MD Le ho feta moo, e sebetsa ho thusa ho thibela tyrosinase, enzyme e bohlokoa bakeng sa tlhahiso ea ncha 'mala; tyrosinase e tlase e lekana le matšoao a fokolang a lefifi. Phetolelo: Vithamine C ka bobeli e thusa ho fifatsa matheba a teng le ho thibela ho thehoa ha tse ncha, ho netefatsa hore letlalo la hao le lula le se na letheba. (Hafeela u ntse u sebelisa setlolo se sireletsang letsatsi kamehla, ehlile.)


Mme qetellong, ha re bue ka tlhahiso ea collagen. Ka ho sebetsa e le antioxidant, e boloka li-ROS tse mpe ho senya bobeli ba collagen le elastin (tse bolokang letlalo le tiile). Liphuputso tse ling li bontšitse hore vithamine C e susumetsa fibroblasts, lisele tse hlahisang collagen, ho bolela Emily Arch, M.D., ngaka ea letlalo ho Dermatology + Aesthetics e Chicago. (Mme FYI, ha ho mohla e leng pele haholo ho qala ho sireletsa collagen letlalong la hau.)

Bakeng sa merero ena ea ho haha ​​​​collagen, lijo tsa hau le tsona ke tsa bohlokoa. Ho ea ka phuputso e phatlalalitsoeng ho American Journal of Clinical Nutrition, ho noa vithamine C e phahameng ho ne ho amahanngoa le letlalo le fokolang haholo.

Nahana ka lona lebaka le leng hape la ho beha litholoana le meroho e nang le vithamine C e ngata joalo ka pelepele e khubelu, lehlomela la Brussels le fragole. (Ho eketsehileng ka seo mona: Mehloli e makatsang ea 8 ea limatlafatsi)


Hopola feela hore e tsebahala e sa tsitsa.

Bothata bo boholo mona ke hore vithamine C e batla e sa tsitsa joalokaha e le matla. Ho pepesetsoa moea le khanya ea letsatsi ho ka potlakela ho etsa hore motsoako ona o se sebetse, o lemosa setsebi sa letlalo sa New York City Gervaise Gerstner, MD Batla lihlahisoa tse bolokiloeng ka libotlolong tse sa bonahaleng 'me u li boloke sebakeng se pholileng, se omileng, oa eketsa.

Hape o ka batla foromo e kopanyang vithamine le asiti ea ferulic, antioxidant e 'ngoe e matla: "Ferulic acid ha e sebetse feela ho tsitsisa vithamine C empa e boetse e matlafatsa le ho ntlafatsa litlamorao tsa eona," ho hlalosa Dr. Lain. SkinCeuticals C E Ferulic ($166; skinceuticals.com) ke thatohatsi ea nako e telele ea derm. (E amanang: Lisebelisoa tsa Tlhokomelo ea Letlalo Li-dermatologists Love)

Ho boetse ho na le sehlopha se secha sa phofshoana ea vithamine C, e reretsoeng ho kopanngoa le moisturizer efe kapa efe, serum, kapa esita le setlolo se sireletsang letsatsi; ka khopolo, tsena li tsitsitse ho feta hobane ha li na monyetla oa ho kopana le leseli.

U hloka feela ho e sebelisa hang ka letsatsi.

Ka sebele ha ho na khaello ea lihlahisoa tse ncha tse thehiloeng ho vithamine C ntle moo; re bua ntho e ngoe le e ngoe ho tloha ho serum ho isa ho lithupa ho isa ho limaske ho ea ho mists ... le tsohle tse lipakeng.

Mekhoa ena ha e na feela likaroloana tse phahameng ka ho fetisisa tsa motsoako o sebetsang, hape e bonolo ho khabisoa tlasa lihlahisoa tse ling, ho bolela Dr. Gerstner.

E 'ngoe ea ho leka: Image Skincare Vital C Hydrating Anti-Aging Serum ($ 64; imageskincare.com). Sebelisa marotholi a seng makae ho pholletsa le sefahleho sa hau sa kamora ho hloekisa sefahleho, pele ho letsatsi - hoseng ho hong le ho hong.
