Ukunakekelwa kwesikhumba: Vitamin C kanye nokuphuma kwayo

I-Vitamin C iyisithako esivame ukusetshenziswa ezimonyoni kanye ne-antioxidant yemvelo engasetshenziswa ukuvimbela nokuthuthukisa izinga lokulimala kwesikhumba okubangelwa ukukhanya kwelanga; Kuyaphawuleka ukuthi nakuba izilwane eziningi nezitshalo zingakwazi ukuhlanganisa i-vitamin C ngokwazo, umzimba womuntu awukwazi ukuwenza ngokwawo futhi ungawuthola kuphela ekudleni kwangaphandle. Ukuthatha uvithamini C ngomlomo kunciphisa kuphela ukwanda kokuqukethwe kwevithamini C esikhumbeni. Ngakho-ke, imikhiqizo yesikhumba equkethe uvithamini C iyindlela engcono kakhulu yokwengeza uvithamini C wesikhumba.

I-Vitamin C kanye nemikhiqizo yayo

Amavithamini amakhulu asetshenziswa ezimonyoni afaka uvithamini C,i-magnesium phosphate , kanye nesundu. I-Vitamin C ayizinzile kakhulu, futhi ukusebenza kahle kokumuncwa kwesikhumba kuphansi. Ukusetshenziswa okulula kuvame ukuhlanganiswa ne-vitamin E, futhi inani lokusetshenziswa ngokuvamile liyi-1% ~ 20% ekulungiseleleni ukhilimu. Njengokususelwe ku-vitamin C, ku-cosmetics kanye ne-lotion,i-magnesium ascorbate phosphateyiyona ezinzile kakhulu, ilandelwai-ascorbate palmitate.

Manje ucwaningo lukufakazele lokhouvithamini C inomphumela wokulwa nokuvuvukala futhi ngokuvamile isetshenziswa yi-dermatology ukwelapha izifo ezihlukahlukene zesikhumba ezivuthayo; Nakuba uvithamini C engazinzile futhi ukumuncwa kwesikhumba akukuhle njengalokho kwei-magnesium phosphate , i-vitamin C inomphumela omuhle kakhulu esikhumbeni! Ocwaningweni, ukusebenzisa ukhilimu onenani le-pH elingu-3.2 kanye nokuhlangana kuka-15% kavithamini C nsuku zonke izinsuku ezintathu ezilandelanayo kungakhuphula okuqukethwe kwevithamini C esikhumbeni izikhathi ezingama-20, futhi umphumela osebenzayo ungahlala izinsuku ezi-4. Kodwa-ke, ukusebenzisa u-13% we-magnesium phosphate kavithamini C kanye no-10% we-palmitate kavithamini C akukwazi ukukhulisa ngempumelelo ukugcwala kukavithamini C esikhumbeni. Ezimonyoni, uvithamini C kanye nokuphuma kwawo kuvame ukusetshenziswa ngokuhlangana.

Ezinye izifundo zomtholampilo zibonise ukuthi ukuqukatha u-15% we-vitamin C palmitate kunganciphisa ngempumelelo i-erythema ebangelwa i-UV ne-UVB. Uma isetshenziswa ngemva kokulimala kwe-UV, izinga lokunciphisa ububomvu lingakhuphuka ngo-50%. Ngakho-ke, i-vitamin C palmitate inconywa ukuthi isetshenziswe ekushiseni kwelanga kanye nemikhiqizo yokulungisa ilanga; I-Vitamin C phosphate magnesium ingagcina uzinzo kumanani we-pH angathathi hlangothi futhi inomsebenzi wokukhipha ama-radicals mahhala futhi ikhuthaze ukukhiqizwa kwe-collagen. Ngakho-ke, emikhiqizweni elwa nokuguga kanye ne-antioxidant, kuhle ukusebenzisa uvithamini C ngokuhambisana novithamini C.i-phosphate magnesium.
